LiquaGen - 6 Stage Reverse Osmosis + Deionization (RO/DI) Water Filter System w/Glycerin Filled Pressure Gauge - 100 GPD | Under Sink Water Filter Machine for Aquarium Water Purification

This unit, the 150 GPD, has been in operation for about three months now. I purchased the unit for multiple aquariums, 2 salt water and a 120 gallon planted tank that requires at least 50% change weekly. Getting TDS as low as possible was the main goal. This unit has been impressive in every way. The build quality is better than expected, setup was easy, and TDS is reduced to 0 or 1 from 350-450 Range. Customer service was excellent, as I did receive my unit needing another resin cartridge. I called around 6 pm on a Friday and had my new cartridges Tuesday, and they even included new fittings for the plumbing. I haven’t measured the flow, but I store right about 110 gallons which I use every week and it takes about 14-15 hours to refill both containers. Unit exceeds expectations for a very reasonable price and I would highly recommend it.

Works fine. I guess it would have cost more and I did pull the old conductivity meter off my old unit but would be nice to have on this one.

Product is solid and works great. Easy to follow instructions. Read the instructions better than I did. My 3 stage DI units on top (my second to last picture) had loose fittings that needed more Teflon. Mine all leaked when I turned on the unit. The instructions do however state to check all the fittings over before install. So that was my fault. More Teflon and re-tighten, and now it works great. Comes with a few different fittings to hook it up to water which is nice. Also mine came with a float control for your aquarium sump for auto top off. (Last picture) You would just have to run a line from your RO DI unit to your sump. Also the digital TDI unit works great as well. Shows you Parts Per Million before water comes in and after water leaves unit. I bought this unit to make clean water for my saltwater aquarium and it's working perfect. Should have bought this two years ago!

It came to me damaged. The frame it's mounted in had a very bent corner, its only cosmetic, but still.. Thou can tell it happened before it was packaged. The pressure gauge leaked and I could not get it to stop by tightening, plus the gauge reads zero at all times. Found they plumed it in between the dionizers and the RO filter. No data anywhere to tell me if this is intentional. So I bypassed it since it was leaking

Product seems OK... but, don't expect any answers or call back from customer service!

The item arrived with missing elbow and clips and some other pieces. the pressure guage was loose in the bracket and was unable to see anyway to tighten it as the hole it was in was larger than the hardware to tighten it. the instructions were VERY poorly written, all in black and white and the worst part was there is a paragraph at the end stating that if there is any broken missing pieces not to send the unit back, rather they will send the items out to you. Also they seem to realize the instructions are poor so they say to call them and they will walk you through the process. Well I was installing this at 9PM on a Friday, I cant wait until Monday to call and hopefully get someone to help me,, they are aware of the poor packaging resulting in damaged units and they know the instructions are only good for fire starter, so why not fix the problems? Absolute rubbish, boxed it back up and sent it back

The system was delivered as advertised, assembly is complete and correct and all the needed parts were included and even a few extra plumping parts were thrown-in. One of the elbows was damaged in shipping but was easily replaced using one of the included extra elbows. This filtration system is an excellent value for the price and I would buy from them again.

Very nice system. Using it for a saltwater reef tank! Excellent!
