I live in central fl, where our water could be generously called "liquid rock." I realize that the fish I buy here (even low-ph fish) are to some extent going to be used to it, and I have had good luck with various species. The main reason I'm considering using RO water is simply to reduce the "crust" that swiftly builds on everything.
I was thinking I'd try a combination of tap and RO if I do it, testing to find a good ratio; that way some minerals still make it and I won't need to add them back in, while hopefully making the water a little less hard and alkaline. Assuming that is viable:
Do you recommend a larger drinking system that would also be used for aquariums? Or a smaller dedicated one? Right now I get 5g drinking water bottles from Lowes, so it *might* be used for drinking. The last system I had got a bad smell in/near the tank that I couldn't get rid of so I'm a bit leery of them for that. If I got a larger drinking one with a tank/faucet, how do you hook those up to your aquarium container (where you'd mix the water)?
Right now my tanks are 10g and 75g, though the 75g may be upgraded to a 150g if I have my way
It will be a planted community tank.
Thanks for any thoughts!
