After some time of keeping a reef tank, it becomes very obvious just how valuable your RO/DI system.

Here at Marine Depot, we carry a variety of cool accessories that will help you get the most out of your RO/DI filter. Here are our top 5 favorite upgrades and add-ons for your RO/DI:

ADD A BOOSTER PUMP

A booster pump increases water pressure into your RO/DI system. This optimizes TFC membrane performance by maximizing product water production and reducing waste water.

AquaFX offers one of the most economical booster pump kits and is extremely easy to install with quick disconnect fittings and a high-pressure switch that automates its operation.

INSTALL A FLUSH VALVE

Flush valves are very inexpensive and super simple to install. The way they work is by creating a by-pass for the flow restrictor which then allows tap water to rush through the membrane at full pressure and wash away debris.

We recommend flushing your membrane for 30-60 seconds before and after every use of your RO/DI system. Flushing the membrane regularly will dramatically increase the lifespan of your TFC membrane and DI cartridge.

ADD AN EXTRA DI CANISTER

A standard RO/DI system will have three vertical canisters and the RO membrane on top. By installing an additional vertical canister you can add an extra pre-filter or additional DI cartridge.
An additional carbon or sediment filter can really help if your tap water has a lot of sediments or contains chloramines.

The AquaFX Chloramine Blaster Upgrade Kit is a perfect upgrade for dealing with Chloramines, as the kit includes the extra canister as well as two chloramine-removal cartridges.

An extra DI canister is great to help ensure that algae fueling impurities do not make their way into your aquarium.

This is especially useful for those of you producing large quantities of RO/DI water on a regular basis. While you will need to spend some money up front, it will ultimately save you money in the long run by helping to increase the life span of the other filter cartridges in your system and giving you cleaner water.

INSTALL A FLOAT VALVE AND SHUT-OFF

RO/DI systems work great for producing pure water for your tank. Unfortunately they operate fairly slowly and, if you need water fast, waiting 6-8 hours or more simply won’t cut it.

By installing a float valve onto a reservoir along with a shut-off valve, your RO/DI system can automatically produce water as needed ensuring you always have fresh RO/DI water available.

The float valve is attached to a reservoir and connected to the product water line from your RO/DI system. You will then need to install the pressure sensitive shut off valve. Most float valve kits, like those from AquaticLife and AquaFX, will include both the Float Valve as well as the Shut-Off.

When the reservoir is full of RO/DI water the float will close and increase pressure in the RO/DI system and trigger the shut-off valve which then stops tap water from entering the unit. When the water level in your reservoir drops, the float will open, pressure will then drop inside the RO/DI system and the shut-off will then re-open and allow tap water to enter the system for filtering.

ADD A DRINKING WATER KIT

When you own an RO/DI system it really makes no sense to purchase filtered water for drinking because you can actually produce clean drinking water right in your own home. A drinking water kit allows you to automatically collect RO water in a pressurized reservoir which is then always available for drinking.

Since you want to collect the water before it passes through the DI canister it is important to follow the plumbing instructions carefully when installing these kits. We offer a Drinking Water Kit that includes a 3 gallon reservoir and all of the necessary plumbing so you can have clean drinking water at your fingertips.
