What to Consider When Choosing Your Reverse Osmosis System
When shopping for a RODI system, you need to consider several important factors. These include size of tank, performance per cost, and tank compatibility.
Tank Size
You should make sure that the RO/DI system will work with the size of your tank. When shopping for a RODI system, check out the gallons per hour (GPH) rating on how much water it can process. For example, a 40 GPH RO/DI unit is suitable for tanks up to 40 gallons in capacity.
Performance Per Cost
Make sure that you are getting a RO/DI unit with high performance at an affordable price. Compare different makes and models of RO/DI units until you find one that meets your needs and fits within your budget.
Tank Compatibility
Make sure that the RO/DI system is compatible with your aquarium before making any purchase decisions. Some systems require certain features like a pH controller or an external power supply while others come complete with these features already included in the package!

What Is A RO/DI System?
A RO/DI system is a filtration system that uses an aquarium pump to circulate the water through a filter and then back into your tank. The filter removes the harmful chemicals in your aquarium, such as ammonia and nitrates, leaving clean and healthy water.
A RO/DI system can also be used to replenish saltwater with fresh tap water. This is especially helpful if you’re constantly running out of saltwater or don’t want to use distilled water, which may contain minerals that can harm your fish’s health.

How Many Gallons per Day (GPD) of Purified Water do I Need?
This is one of the most common questions that new RO/DI users ask. There’s no perfect answer, but we can give you a general direction to follow.
The amount of water you need to purify depends on several factors including the size of your filter and how much water your aquarium loses each day.
If you are just starting out, we recommend that you start with a 2 GPD system. This will provide enough water for your fish to survive for a week or two at a time and will help you determine whether or not this is something that you want in your tank!
After determining that RO/DI is right for your tank, we would recommend purchasing an additional 1 GPD every month or so until you reach your desired capacity.
Below are some guidelines for calculating how many gallons you need to purify each day:
- If your tank is 10 gallons or less, you will need 3 GPD of purified water.
- If your tank is 11-20 gallons, you will need 4 GPD.
- If your tank is 21-50 gallons, you will need 5 GPD.
- For larger tanks we recommend a 6-10 GPD system.
As a general rule of thumb, you should always have enough water to keep the fish alive for at least one week in the event that your filter fails or if there’s an extended power outage. You should also add an additional 1-2 GPD of water every week to account for evaporation.
You can calculate your system’s capacity by multiplying the tank’s volume in gallons by the number of gallons per day you need to purify. For example, if your tank is 20 gallons, you will need a 6 GPD filter. If you have a 50 gallon tank, you will need 8 GPD.
We recommend that you purchase a filter that is at least 1 GPD larger than the amount of water that your system needs to purify. This will allow for some buffer room and help ensure that your system doesn’t overwork itself in case of a power outage or if there is an extended period without sufficient water flow through the filter.
For example, if you have a 10 GPD filter, you should buy a 12 GPD filter.
The final piece of the puzzle is the pump. There are two types of pumps that you can use to power your filter.
The first is an electric submersible pump, which is powered by an electrical cord. This type of pump does not require any power and will deliver enough water to your tank for at least one week in the event of a power outage or if there’s an extended period without sufficient water flow through the filter. The downside to this type of pump, however, is that it can be expensive and require maintenance (i.e., cleaning) and replacement parts (i.e., impeller).
The second type of pump is a submersible pump that uses a battery to power it. The battery will last for months before needing to be replaced. This type of pump is much more affordable, but it can be more difficult to troubleshoot and maintain (i.e., cleaning).
We recommend that you purchase a submersible pump that uses a rechargeable battery pack. This will allow you to get the most out of your money while providing you with the peace of mind that comes with having an off-grid system in place.
Why Unfiltered Tap Water Causes Trouble in the Aquarium?
The aquarium water is full of impurities. There are many kinds of impurities in the aquarium water, but the most common ones are:
1. Nitrite
The nitrite level is usually almost double the amount recommended by experts. Nitrite is a toxic gas that can kill any fish in your aquarium if it gets into their body. If a fish dies, you may lose all of your other fish too.
2. Ammonia
The ammonia level is usually at least double the amount recommended by experts because most people use too much salt to keep their tank’s water clean and add more ammonia to their tank than they should have, which will cause ammonia to build up rapidly in the tank and may lead to a fish’s death.
3. Phosphate
This is a very harmful substance in the tank and can cause a fish’s death if it gets into the fish’s body.
4. Nitrate
The nitrate level is usually at least double the amount recommended by experts because most people add too much salt to their aquarium and use too many fertilizer tablets, which can lead to nitrate build-up in the tank and may lead to a fish’s death.
5. Copper
Copper is poisonous to fish and can cause a fish’s death if it gets into the fish’s body. If you are using an aquarium filter, then you don’t have to worry about this because there will be no copper in your water that would get into their bodies.
How Does a Reverse Osmosis Filter With Deionization Work?
A reverse osmosis filter with deionization works by removing all the harmful substances from the water before it is passed through the filter. These harmful substances are usually dissolved in the water and can’t be removed by a normal water filter because they are too big to fit through a normal filter. A reverse osmosis filter with deionization has three parts:
- The RO membrane is made of very fine plastic material that is permeable to all substances except for salt, which passes through it. This membrane collects all the hazardous substances dissolved in the water and passes them through it into an outside container for disposal.
- The brine tank is filled with a special type of salt that has been made so that it can’t dissolve in water. What it can do is absorb all the harmful substances, including those dissolved in the water and those that are too big to fit through the membrane. It also can be used to make a strong brine solution for cleaning and disinfection of water, as well as for making ice cubes and other things.
- The RO unit’s pre-filter is made of a very fine filter material that is permeable to all substances except for salt, which passes through it. This pre-filter collects all the harmful substances dissolved in the water and passes them through it into an outside container for disposal.
How RO process for Aquarium works
Filtration Stages of a RO/DI Filter for Aquariums
Stage 1: Pre-Filter
The first stage of the filtration system is a pre-filter. This filter is used to capture particles that are larger than 0.2 microns in size. The pre-filter is used to remove any debris that may have been stirred up in the aquarium by the pump or circulation system.
Stage 2: Carbon Block Filter
The next stage of filtration is a carbon block filter. This type of filter will remove particles from 0.1 to 0.3 microns in size, as well as chlorine and chloramine, both important components of aquarium water. These filters are also effective at removing heavy metals, such as mercury and lead, from aquarium water.
Stage 3: Cartridge Filter
The final stage of filtration consists of a cartridge filter. The cartridge filter is used to remove particles from 0.005 to 0.01 microns in size, and it is also effective against bacteria, viruses, and cysts.
Types of RO/DI Membranes
There are several types of RO/DI membranes, and they all have their own advantages and disadvantages. The membrane that is used in a particular RO/DI system depends on the size of the tank and the number of gallons of water being purified. The most common type of membrane is a pad filter, which consists of a pad that has pores between 1 micron and 0.0001 microns wide, with each pad containing about 2 million pores per square inch. The pads are placed in a plastic frame that is placed in an aquarium or other container.
Another type of membrane is the cartridge filter, which uses cartridges to remove particles from the water. There are three types of cartridges: foam, gel, or ceramic; each cartridge has its own advantages and disadvantages.
Foam Cartridge
Foam cartridges are the most common type, and they are made of polyurethane foam. Foam cartridges have a porous surface area of about 3 square inches by 3 square inches, with each pad containing about 2 million pores per square inch. The foam cartridge is placed in a plastic frame that is placed in an aquarium or other container, where it is submerged in the water. The cartridge filter has a porous surface area of 3 square inches by 3 square inches. The foam cartridge has a small amount of air trapped inside it; this air allows some water to pass through the pores of the filter, but not all of it does so.
Gel Cartridge
Gel cartridges are also made from polyurethane foam, but they contain a polymer called polyvinyl alcohol (PVA), which is used to make the filters more durable. The PVA molecules form a gel as the water passes through them, which makes the cartridge last longer and prevents the filter from degrading.
Ceramic Cartridge
Ceramic cartridges are made from aluminum oxide, and they have a porous surface area of about 1 square inch by 3 square inches. The ceramic cartridges are placed in plastic frames that are placed in aquariums or other containers. Ceramic cartridges filter water quickly; they also allow almost all of the water to pass through them, unlike foam and gel cartridges.
How Often Should You Change RO/DI Membrane?
This is a common question. The answer is: “It depends.” I recommend changing the RO/DI membrane every 6 to 12 months. The only way to know for sure is to test the water pressure and water quality. If the pressure is too high or the pH of your tap water too low, you should change your membrane cartridge. If you have a well-designed system that works well, you will not need to change your membrane cartridge very often.
What Size RO/DI Membrane Should You Use?
The size of your RO/DI cartridge depends on how much surface area it has and how much water it can hold at one time without losing its ability to filter bacteria, viruses, and cysts.
If you have very large tanks (more than 100 gallons), you can use a 10″ x 10″ RO/DI cartridge. If your tank is larger than 200 gallons, I recommend using a 20″ x 20″ RO/DI cartridge. If your system is smaller than 100 gallons, I recommend using a 10″ x 10″ RO/DI cartridge.
Is Reverse Osmosis Good for Aquarium?
Reverse osmosis is a process that removes dissolved substances and impurities from water. It uses pressure to push water through a semi-permeable membrane to filter out impurities. The end result is pure, clean-tasting water that you can use for aquarium maintenance. Reverse osmosis systems are often used in aquariums for filtration and aeration purposes.
RODI systems have been proven to be an effective way of maintaining your tank’s health, but they are not 100 percent safe or effective at removing all harmful substances from the water. There are other methods of cleaning your aquarium’s water like using live plants and activated carbon filters.
What Is the Most Efficient Reverse Osmosis System?
The most efficient reverse osmosis system will vary depending on the size of your tank and what you want to filter out. Generally, a 4-stage RO/DI system can be used for smaller tanks (less than 100 gallons) where a 3-stage or 6-stage system is necessary for larger tanks (up to 400 gallons).
A 4-stage RO/DI system includes a pre-filter, sediment filter, carbon filter, and post filter. It also has a built in timer that can automatically shut off the unit after 24 hours. This is great if you’re not able to monitor the water levels in your tank every day.
A 3-stage or 6-stage RO/DI system includes a pre-filter, sediment filter, carbon filter, and disposable membrane cartridge with an activated carbon bed cartridge. The membrane cartridge is the only part that needs replacing when it’s time for replacement. These systems are more cost effective because they provide better filtration than models with only one membrane cartridge.
How Do I Install a Reverse Osmosis System in My Aquarium?
Installing a reverse osmosis system is not difficult. It does require some basic knowledge of how aquariums work, but the install is straightforward.
The first step is to find the appropriate size for your aquarium. Next, add the appropriate sized filter and a water pump. Your next step will be adding water from your tap into the tank and then filling up the rest with distilled or deionized water. After that, you’ll need to attach all of the pipes for your RO/DI system and then run it as directed by the manufacturer.
How to install RO/DI system for your aquarium
How Do I Keep My RO/DI System Working Properly?
Cleaning the cartridges is the most important part of maintaining a RO/DI system. In order to get the best results, you should clean the cartridges once per week (more often during heavy use). To do this, you should remove the cartridges from your tank and fill up a gallon of distilled water. Then, put one cartridge in the water for about 30 seconds. Then, remove it and repeat this process with another cartridge.
Can You Use RO/DI Water for Freshwater Aquariums?
A RO/DI system is a must for any aquarium owner. In order to keep your aquarium healthy and thriving, it’s important to use a quality filter. A RO/DI can help remove the harmful bacteria, nitrates, and ammonia. However, you should use a different type of water once the waste is removed from your tank. You cannot use the water that was filtered by your RO/DI as it may contain too many toxins. If you want to use the water that comes out of your RO/DI to create a freshwater fish tank, this will not be possible because it will contain too many toxins and harmful chemicals.
What’s the Difference Between RO and RO/DI Water?
There are two main types of water filtration systems, RO and RODI. The difference between the two is that RO filters out the dissolved solids while RODI filters out all of the particles. This means a RO system would only filter out the unwanted nutrients that are in your water, while an RODI system would remove everything.
RO/DI systems provide continuous water flow, meaning they continuously filter your tank water.
Do You Have to Use RO/DI Water for Saltwater Tank?
Typically, yes. Saltwater tanks require a lot of water exchange and you’ll need to use a RO/DI system in order to ensure that your tank is properly filtered.
FAQs
RO/DI systems require a lot of water, so you’ll need to use at least 1000 gallons per day. This means that you’ll have to have an adequate filtration system installed before you can start using your RO/DI system.
This depends on how much water your RO/DI filter is removing from the water. If it’s removing too much, then it will need to be replaced every month or two. If it’s removing too little, then there won’t be enough nutrients in the water which will result in algae blooms. You should also change your media in your filter every month or two.
No. Just like all other filtration systems, you’ll need to clean and change the media in your filter every two months.
To start using your RO/DI system, you’ll need to fill the tank with tap water and then add as much tap water as you think is necessary (for example, if you have a 10 gallon tank, then add 10 gallons of water). Then, turn on your RO/DI system and let it run until the water has reached its desired strength. Then, turn it off and let it run for another hour or so to make sure that all of the minerals have been removed from the water.
Yes.
First of all, you must use reverse osmosis (RO) water to use a RO/DI system. If you use tap water, then you won’t be able to remove the minerals from the water.
Secondly, when using a RO/DI system, it’s important that you change out your media and clean your filter every two months or so to prevent algae growth.
Finally, it’s important that you follow the manufacturer’s instructions for your particular RO/DI system and never attempt any chemical or mechanical filtration with them!
Final Thoughts
RO/DI systems have become the gold standard in aquarium filtration. They are reliable, inexpensive, and efficient. Nowadays all the major manufacturers have an RO/DI system for sale, and it’s not difficult to find one that suits your budget or needs.
The RO/DI system is a great way to keep your aquarium and its inhabitants healthy, while saving money. The only downside is that it takes some time to set up an RO/DI system and you will need to buy some new equipment. However, if you can handle the cost and time it takes to set up your system then this will be a great investment for you.
