I was wondering what RO unit should I get. All I would need it for would be for is a 125 and 90 planted tanks. I need some supplemental RO water because I have very hard water currently I am at approx. 340-358 ppm or 19-20dkh. I would like to have the cheapest RO water unit possible, with that being said I also want some quality. Found this what do yall think and do yall have any recommendation. found this one its the cheapest I can find
