Comments: Produces very pure water but has some leaks to work through and requires alot more time to produce water than you would think. Overall it is a great product and you get a 15% discount on replacement filters for life.

Comments: I received the 35gpd delux version as a gift. I'm going to be returning it to buy the 35gpd pro unit. I'm only getting about 1 gallon/2 hours with this unit. Part of the problem may be because i have no idea about the PSI. I don't know the difference between what 5psi looks like and what 100psi looks like so I don't know if the pressure is correct.

Comments: I love this product but had to go through the whole system and check all the seals, the first run of it found me scrambling to clean up water leaks throughout. I found that plumbing tape on the threads fixed the problem. This is a great product and should be in every salt water setup for best results!

Comments: I had received the 60 gpd unit and first thing out the box as I open it is a broken elbow fitting in the most protected spot which striked me as odd.. minus 1 star then I buy a elbow which cost me $7 cause they make me wait a week to ship then strike 2 is when I finally hook everything up elbows start leaking which i had to rewrap everything.... I still like the unit so far besides everything

Comments: I tested the water that came out of this skimmer and its just perfect.

Comments: after opening the product, I feel the backing where it attached to wall could be stronger.More lengths of hose.more attention to parts used such as how & where water travels,how to replace or change parts if something breaks.

Comments: Works well, wish that it came with a auto shutoff valve on it. Mine doesnt seem to make a lot of water, we will see what it does once the water supply warms up.

Comments: I just installed it and am filling my 240gal tank. works great so far!

Comments: Easy to use. Wish I had purchased an RO system years ago and saved myself all those weekly trips to purchase water.

Comments: System works great right out of the box. Just wish there were better instructions and more info on the thing!

Comments: great! built well durable and 0 TDS enough said.

Comments: I've used this RO system for Saltwater tanks and also for drinking water for over 10 years and never had any trouble with it. Not only does it produce best-in-class RO/DI water but it's held up to a lot of abuse over the years. Replacement cartridges are reasonably priced for the quality level which has made long term operating costs relatively low. For over a decade we've been drinking the healthiest, highest quality RO water, so overall I'd have to say that this has been one of my best investments. I couldn't give this product a higher recommendation or rating!

Comments: great product

Comments: Wonderful product works like a dream, plus no more lugging water jugs!

Comments: Great product, good deal.

Comments: I have been using tap water on my tank for about 6 months. Recently there has been something in the water that has caused the fish stress. All were breathing heavy, one, my puff, passed away.
<br />
<br />I tested my water levels all tests were negative. I ordered this product, used it for a 20% water change and poof, 3 hrs later the other two fish were fine.
<br />
<br />If anyone else out there is using tap water, you never know what is going to be in it. The water could be fine for years and then poof something changes killing your fish.
<br />
<br />I would suggest that everyone gets something like this.

Comments: i have only made 100 gallons or so with this unit so far, and thus far it produces very high quality water. the unit did not come with any instructions and one of the hoses was kinked, but overall a very good value.

Comments: dont have a test kit that shows any levels of anything
<br />in the output water that should not be in it
<br />could have better fitings on the water lines

Comments: My fish are all so happy since I have been using this RO/DI unit they have been doing dorsal flips all day & keeping me up at night playing marco polo! I even caught my crustaceans blowing kisses at me!! My suggestion to you is if you
