yeah ive been looking into an RO unit. trying to find one that hooks up to a tap, bc im renting and cant run plumbing. and as far as everyone flaming me on my water changes, theres a much better way to express an opinion to someone. on this site u should be a little more friendly and informative. if someone actually explained why i should do more wc id be more likely to do it. its like if u only change your oil every 15k mi and your car still runs fine u wont see why u should do it every 3k. but if a mechanic explained why u should.... my view on dechlorinating chem. is u cant turn something into nothing. so what does it turn into? everyone does their wc diff, from daily to not at all. so how am i to know what is actually needed.
