Has Anyone Tried This?

Put that under your tank, hook up a pump, and it cleans the water allready in your tank. Well, that's the theory at least. Would be useful for the larger aquariums, and would make life much simpler. Dunno if anyone has proposed this, I'm new here, so I don't know that much. Don't have a tank atm either.

Performing reverse osmosis on your tank water would:
1. clog your reverse osmosis membrane
2. remove all necessary minerals from the water
3. remove any microfauna that some inverts live on

Oh, shows ya what I know then. Oh well. Looked good on paper though.

But wait, people use R/O on their tank water. What if someone had a 180 gal, and ran the R/O machine for an hour and a half every sunday instead of doing a water change? That would change out close to 25%, which some people change out with R/O water anyways.

Good old fashioned water changes can never be substituted for anything else. People use RO water primarily for reefs to remove any impurities of tap water. Though they remove contaminents, they remove minerals that keep your fish alive. In saltwater aquariums, the minerals are added back through the salt. In freshwater salt cannot be added. Also your membrane would neeed to replace quite often, and the membranes are not cheap, at least $90 US dollars. For a single 60 GPD RO unit, membranes cost around $120.
