I've been running my 75 gallon planted with some mopani wood, giving it a nice tea color. Letting the tannins color the water was intentional, as I was trying to make a more Angel friendly home, which it did, maybe too well.
Recently I've doubled the lighting to bring it from a low light to a medium light tank. So now the tannin effect has gone from a natural look to an ugly tea effect.
After about a half dozen big water changes, it still has that annoying yellow tinge to it. Would activated carbon or maybe even some co2
help clear it up any faster?
might be a little tricky though. I doubt I could slip the cost of a ph monitor set up past the wife, so it'd have to be a timered system. I'm still kind of wary about that since I have very soft water that could crash if I look at it wrong.
