Yeah, I suppose that information would help :)
I am changing 5 gallons of water twice per week, so about 20% per week. I have
to clean the tank that often anyway, or I can't see through the algae that
collects on the glass.
Even after the water change, my NO4 reads 40-60 ppm. The main reason I added
live plants was to minimize the frequency of water changes, while still keeping
the discus happy. Granted, they seem much happier, but I'm not -- although the
tank IS much prettier.
One reader has already responded that he thought I was overfeeeding, so unless
you have any other ideas, I'm going to give that a try for a few weeks.
Thanks for all your input.
