Premium Reef Supply units are assembled right here in Indiana. We are able to watch quality control over them very closely. We have been in search of a lower priced RO/DI unit for quite some time but also still wanted to keep quality high. For the price, it’s hard to beat the quality of construction and higher grade parts with these units. We feel Premium Reef is the best “no frills” less dollar bills RO/DI you can find and still keep that quality of materials. The RO membrane housing and canisters are industry standard, so changing the membrane or filters is a snap. We can even have one built with SpectraPure or Kent membranes for additional cost. Features Clear O’ring Pre-filter Canisters for extra water protection John Guest Speed Fittings through out unit for easy tubing changes. Standard 2.5" x 10" 1 Micron Sediment Filter Standard 2.5" x 10" 5 Micron Carbon Filter SpectraPure 2.5" x 10" Silica Buster Color Change DI Resin Cartridge Filmtec TFC Membrane provides proven high performance for consistent reliable water purification 5 Feet of feed, good, waste water line tubing 1/4" John Guest brand. Garden Hose Fitting w/speed fit   ONLINE INSTRUCTIONS: Your new Premium Reef Supply system comes completely installed. The diagraph above is a view from the front of the unit. 1st Stage. It’s a 1 micron sediment filter. It’s industry standard 2.5 x 10” size. You can use .5, 1, 5, 10 or 20 micron in the future if you prefer. We recommend you change your micron filter every 4-6 months. 2nd Stage. It’s a 5 micron carbon block filter. It’s industry standard 2.5 x 10” size. You can use .5, 5 or 10 micron carbon block, or granulated. We recommend you change your carbon block filter every 6 months. 3rd Stage. This is your RO Membrane. Inside is an industry standard Dow Tec TFC Membrane. Under normal circumstances it should last 2-5 years depending on water quality and use. You can use other brand membranes in the future and other GPD rates as well. If you change from 50gpd, you just change the flow restrictor located on the yellow line connection. 4th Stage. This is the 3rd canister, but the 4th stage in the unit. It has a Color Change DI cartridge installed. We use SpectraPure Silica Buster DI. This has a blend of DI resin to remove organics. When it’s completely exhausted it will change color. So when all resin has changed color it’s time to change. On average, you will get around 250-300gallons of product water before needing replaced.   Color Coded lines. You have 3 colors of water lines. Black is your input feed line. You connect your black feed line to a water source. Example would be a laundry sink hookup, or taping into your water line in your house. The yellow line is called your waste water or rejection line. Any water that does not pass purified through the membrane gets rejected down the yellow line. You just run this line down a drain. The BLUE line is your product water or good water line. This is purified RO water. You run this into a storage tank, bucket, etc whatever you prefer. If you want to setup a top off system, with a float you’ll need a top off kit and that includes a solenoid to install on your RO to shut off the waste line. Starting up your unit first time, we recommend running around 5 gallons of product water and discarding. This will ensure the membrane was flushed out of any possible dust or contaminants from the factory. Then you are ready to go.  We recommend feeding your water off either a cold line, or warm water up to 77 degrees will yield the best results, but be sure not to go over 77 degrees or you can damage your membrane. We recommend a minimum of 40psi water pressure, which most households should have. If you are low on pressure, you can add a booster pump to increase pressure. Enjoy your new unit and thank you for purchasing a Premium Reef Supply unit.

5 Wonderful	03/08/2009 - by Brandan Kelter from Brownsburg, IN US
I don't see how you could find a better RO/DI for the price. I find no reason to spend hundreds on RO Units when you have these great units offered by Premium Aquatics!
5 Love it	01/19/2008 - by Donald Burbage from Ravenel, SC US
Best unit for the money have had it for 5months now and no problems with it.
4 Instructions???	12/05/2007 - by David Kownick from Bloomington, IL US
This is a nice unit. Quality construction. I was short a filter membrane but they sent it within 2 days. I have not come close to the 50 gallons per day but I believe its because I ran the feed off of my cold line and it's winter time. Not a real big deal. I do wish they would have included a instruction guide along with a trouble shooting index. Just food for thought. I am happy with the unit. Lots of bang for the buck. I would buy again.
5 Excellent	10/16/2007 - by John Reckel from Lebanon, IN US
Adding my review to bring up the average from the reviewers that only gave this unit a "4". It really deserves a "5". Excellent bang for the buck.
5 Works great!!	07/21/2007 - by Anthony Hunt II from Columbus, OH US
Very Happy with this unit. Nicely constructed Great value for the money. I would recommend this unit to anyone. Uses the Spectrapure DI is an added bonus. Like some others said just make sure the fittings are tight before you turn on the water. As usual PA comes through with another quality product.
5 Works like a champ!	06/25/2007 - by Scott Edens from Greenwood, IN US
took 15 minutes to set up. Made sure all fittings were tight(see earlier review concering the John Guest fittings). Brought 400PPM TDS down to 0. Cheap and uses Spectrapure DI resins. Highly recmmended.
5 Nice Find!	06/08/2007 - by PB from Indianapolis, IN US
I have a Kent Hi-S Ro/DI that needs a new membrane and all the canister filters. For me it was cheaper to purchase this entire unit than to replace the parts on my Kent model. After using this unit for 2 weeks, I'm completely satisfied with it. My incoming water TDS is 500+ppm and the output TDS is 0ppm. No leaks, no worries. This unit is well constructed and I would recommend it highly!
4 Works great after re-sealing all the fittings	03/11/2007 - by Pete Zarras from Morris Plains, NJ US
I caught the review that said that the canisters need to be tightened on this unit, so I made sure to do this before installing this unit, but that wasn't enough. I had slow leaks from all of the John Guest 1/4" fittings and even from 2 of the canisters. I went to Home Depot and picked up some plumbers dope and re-sealed every fitting on the unit. No more leaks and I've made a bunch of water in the last 36 hours.
5 Make sure the canisters are tight!	08/09/2006 - by Donald Doyle from Indianapolis, IN US
I just got done connecting the RO/DI unit to my cold line. Water spewed all over the place. The canisters were not tight. Other than that . . . so far so good! :o)
4 Big Bang for the Buck!	08/08/2006 - by Patrick Fitzgerald from Lexington, MA US
I have been using my Premium Reef 50gpd 4 Stage RO/DI Unit for a few months now and I must say I am pleased with it. My nano and my in process 29 are doing great on it. My roomate even uses some of my water for her betta occasionally. These units are great all around. I would especially recommend it to those new to the hobby and those on tighter budgets. You get much more filter for the money!
