LiquaGen Portable - 6 Stage Dual Use (Drinking & 0 PPM Aquarium Reef/Deionization) Reverse Osmosis Water System (RO/DI) w/pH Alkaline Mineral Restoration Filter (75 GPD)

8 year update. Still works great! Have changed out filters every once in awhile! No leaks. Nothing has become brittle or broke over the years. I have added a pressure gauge and that's what I use to gauge changing the filters.Bottom filters changed atleast once a year. The drinking water filter above the bottom 3 have changed out twice. And haven't had to change out the 0 tds filter. It works I don't even check the TDS or EC except once every other month or when I remember now!Needed one for my hydroponic setup. Using well water out here and it was 350ppm and after using the unit is down to 0! The drinking water side of the unit seems in the blind test trials the family chose this unit over the one we had installed. Built to last. No cheap feel to it. Used the tech number provided, fast and friendly help. Quick and easy install. Use the blue clips they provide. Overall great unit and replacement filters are priced good! Small footprint compared to the one installed under the sink. A few extra addons like a float and automatic shutoff valve really compliments this kit.Update a year later and it has been performing flawlessly! Has been used to fill 60 to 100 gallons a day. No problems!2 years! What can I say I have changed the filters and they still looked brand new! Family still pefers this RO system. My plants love it! It is a great product. No signs of it becoming brittle no discoloration in the clear filter housings. No leaks. Overall awesome product! Prices on single replacement filters have gone up in price. Cheaper to buy the bulk 6 filter kit. Still filling up a 330gal tank a month hasn't slowed it down.

Time for a honest review. I used a TDS meter and from 837 well water to 0 TDS. I could not ask for more. Not only does it produce ultra pure RO/DI water it also produces drinking water that is safe for me and my family. One elbow did come broken but it came with many extra parts. I was able to replace the elbow and everything worked. I would recommend attaching all the blue taps to the tube connectors to hold them in place. Seem the instructions lacked that clarification. I looked around for a unit and took a big risk buying this product with zero reviews at the time, worried it would not work good. Most positive points are, one it is made in the USA, it is half the price of units that do not even come close to its rating. Two you are getting quality drinking water. RO/DI water is not safe to drink its too pure, you need a mineral filter which this unit has. I will be making my money back in no time. Third buying point is filters are cheap you can get 3 year supply for 50-60 bucks. ARE you kidding me, I am so sick of other companies over pricing their filters this company is keeping it legit. As for the new 1 star review for not coming with things you normally have to buy separate with most units or pay 300+ for, its crazy amazon even allowed that review because they never advertise it came with those. I can not see anyone who seriously wants to save money and making 0! TDS water for their reef tank being unhappy. If you need an auto shutoff, float switch, or meter you can pick all those up fairly cheaply and the tubing is universal. WHAT A GREAT BUY and I am very thankful I took the risk with zero reviews at the time. Keep it real LiquaGen, I like your homemade booklet too it was insightful, but may want to make sure to point out to connect the blue taps to the pipe connectors for us laymen.

This RO/DI unit was purchased for makeup water in my salt water aquarium. The instruction. The Alkaline water feature for drinking water was an appealing factor in the purchase.The instruction sheet was somewhat vague as to a peppermint installation and hooking to a permanent water supply and filter placement.and permanent installation. The use of a garden hose as a water source is unacceptable.Daily calls to the Company over a two week period went un answered. The questions I had were: 1) Could the unit be installed to a perminant high pressure water source, 2) Life of the filters, 3) use of an automatic flush valve, and 4) Use of an accumulator tank for the drinking water section.These questions remain un answered. Customer service is horrible.

For the price this is an amazing RO/DI unit. I put a TDS meter on it and it easily reduces the inbound 190 PPM of my city water to 0 after the DI stage. After the final carbon/ALK filter it rises to 19 PPM with a PH of 8.6 and ALK of 9.4. A tad high for a reef tank but the PH will come down in storage. Setup was straight forward, although the supplied feed and waste lines are very short. Please keep this in mind if mounting more than a foot or two from the water spigot and drains, otherwise you will need to purchase extra hoses. My only complaints with it were none of the hose barbs, and retaining clips were installed, and the DI and ALK filters were installed backwards. I had to get teflon tape and replumb it, I can't knock that for how well it performs. With 50PSI on the inlet this unit will filter 5 gallons through all 6 stages in about 40 minutes.

This filter is legit, works like a charm! It actually dropped my local tap water from 600+ ppms to literally 0 ppms. The drinking water actually is drinkable as well, although I would let the water run from it a bit, otherwise you will get a nasty earthy after taste.One setback however is that the hose connector they sent with the filter came in shaved (as it was fully plastic for some reason) and would waste a large amount of water. Normally this would affect the review of the product, but the customer service from these guys are great. All I did was send an email saying that my hose connector came in damaged, did not even send a picture but they still sent me a new one, and guess what?They sent the more expensive brass version; no more leaks!

The initial unit hook up was clearly incorrect but the instructions about correct tube installation are vague as if the creators of the product either needed to keep it a secret or themselves had no clue how this thing is supposed to be installed. I will have to figure it out through trial and error and hopefully the whole thing won't blow up in my face literally and figuratively.
