I have Discus and neons and they do benefit from R/O water. Depends on
what you are keeping. If you are keeping African cichlids dont think about
R/O, it will cost you a lot to harden it again. It comes out very very
soft, 1 DKH, and very very pure, nitrate free, also very acid ph about 6 .
To mimic the habitat of discus and neons I use R/O.
If you water comes out not so good, you can think about R/O, but as I said
it will cost you to put in the minerals that it looses during filtration,
use R/O right from Kent to put in the minerals back.
hope this helps
