I use CO2 but not in discus tanks. I prefer to keep things very simple in a discus tank, so as not to take any uneccessary risks, like rapid pH swings which could occur. Just me being extra careful. I do know a number of discus-keepers do run CO2 in their discus tanks without problems, but they monitor it very well.do you run co2? I would like to have plants in my discus tank!
I'm remember that one. Glad to hear it is doing so well!P.S.
And Rick, my daughter still has a few of the discus that you sold to me about a year & a half or so ago, including the last ghost I got from you, which is about 8" now - largest & gentlest discus I've seen for many years !
