This unit was the best money spent. It was easy to install an been working like a champ. It has been very convenient and saving me money from having to go buy salt water and top off from my LFS. I have mention it to all my friends and family that are in the Hobby... Great value

This is my second RODI system - the first one I purchased from another vendor. It was a fancier 5 stage system. Both of them produce 0 TDS water. However, do NOT go lower than this system. The flush valve is very important to RO membrane lifespan and the TDS meter is also great to have.

For all first time RODI buyers, there is a good chance that your water supply will not produce enough pressure to make the system effective. If you live in an apartment building, there is a 90+% chance that this will be the case. For that reason, I'd highly recommend purchasing a booster pump.

All in all, an exceptionally high quality unit.

This is an essential piece of equipment for an aquarium. I have been using it for a couple months now and absolutely love it. The best RO/DI unit i have ever seen.

Great value. Everything comes assembled and ready to use.

Hooked up, turned on the water and got sprayed in the face. Disassembled the unit and one of the fittings was cracked in half. BRS closed all weekend, so I replaced myself.

Build quality seems great otherwise.

Just getting started in the saltwater game, and every piece of advice I've had from seasoned reefers starts with "Get a RO/DI unit" and right after that is "and get it from BRS!"
Fast shipping! Easy to hook up and superb support if you actually need it.

I had been paying for water at my LFS, but realized there water was not clean and caused some issues in my tank. So i was actually using tap water for a few months till i found a RO/DI unit i liked. I was really happy a friend recomended bulk reef.

The box arrived quickly and was packed well. The unit is heavy. it can be moved easily, but it is heavy and i can see the benefit of mounting it under a sink or next to a utility tub.

I conntected the filter to my utility tub in the basement. The tub spigot has a garden hose type connection. I turned the unit on and let it run for an hour to clean ot the filters. i came back to find a puddle of water on the floor. however this was NOT the fault of the filter. I dont often run the sink too much, and basically the faucet is old and unknown to me it was leaking. So i think between leaving it on for an extended amount of time, plus the backpressure associated with getting the water into the filter caused a leak with the utlity sink. Again, this was not the filter's fault. I only mention it to alert people to be sure to use a faucet that is in good working order.

I dont have any other indoor locations to attatch the filter, so i attached it to my outside hose bib. The weather was above freezing. I had the blue line placed into a bucket, with the black (waste) line going out into the yard. At first, i would say the filter was making about 1.5 gallons an hour, the pressure was reading around 60 (if i remember correctly).

The filter does have a built in tester, but i found it to be a little bugging in reading the incoming water. I have a pocket sized tester and my tap water is generally around 140ppm-160pp. The filtered water was coming out at 0ppm. YAY.

After having used the filter a few times, it is filtering quicker. I get about 2-3 gallons an hour. I think some of thie matters if there are other water demands on the house (like the dishwasher or washing machine).

The filter is very easy to use. It only took me a few moments to get it running. The instructions it came with are nice and i know if i had issues i could contact bulk reef.

I recomend this filter and i am very happy with it.

BTW, i have tasted the water out of the filter. It basically just has no taste, or at least tastes super clean. It it is also hard to describe the smell. There is basically no smell, but i still feel like i smell something, i think it is just a smell like clean.

I only have a 29 gallon tank with a mixture of very friendly fish and zoas and a hairy mushroom. I am working on switching out tank water with the new RO/DI salt water. I cannot say i have seen differences yet with my critters, but i can say my zoanthids look a little more open.

This is the best RO/Di filter period. I absolutely love this filter. One of the best buys I've made for my aquarium. Great price point as well. Looks great! thanks BRS

I picked this up from BRS while shopping for other RO/DI units. The unit was packaged great, the operation is SIMPLE! I have it hooked up to my washing machine line with a simple on/off. My TDS meter is 100% accurate and I'm currently producing 0 TDS in my product water. Great value from BRS for this system. I would recommend this to anyone looking for a solid RO/DI setup.

Don't have to run to the LFS to get water anymore!
Don't have to worry about water from the LFS possibly not being up to standards!

This system is best paired with the TDS meter. Seriously, like someone before me said, I wouldn't get a unit without one. Measures TDS in / out.

Flushed the system for one hour, and started producing 0 TDS water right away.

Color change resin with clear plastic housing is beneficial, too. You'll be able to tell if you're producing safe water and gauge how much longer you have 'til cartridge change time.

Great deal!

Bulk Reef Supply has done it again with a great product. Amazing value and quality that I have come to expect from BRS. Thanks for only using the best quality filters and fittings. Will always recommend you first.

I had never used an RO/DI unit before and this one was simple and easy. My water is crystal clear and the problems I used to have with algae are gone. I did have to buy a booster pump because I was getting my water from a well, but it was very easy to install. I will never have an aquarium without and RO/DI unit. Great product and is made very well.

I bought this on sale on black Fri, along with the 150 gpd upgrade kit, the EZ angle adapter kit , the saddle drain clamp and the auto stop top off. Add a 30 gallon rubbermaid trash can and it is a joy to behold. The upgade was installed by BRS, and everything worked perfectly right out of the box.
