Review on Aquatic Life 5 Stage Hydroponic Filtration by Dustin Keller

I have well water with a very high TDS (just under 500). After going through this reverse osmosis unit I have 12-16 TDS readings. I'm guessing that it has a diaphragm flush valve (I had to add a bypass valve on my old unit). Filtering water at 77° from my well is awesome, hence my gpd is much lower - I produce 5 gallons in less than 2 hours from my well in Ohio. I don't want to use warm tap water as I have a softener - not good for aquarium water. I contacted support because I realized there is a DI cartridge that fits this device. One of my aquariums will benefit from RO/DI water.
