I have the beginnings of BBA in my low light tank. It has about 1wpg, and I dose K (due to mild K deficiency signs on the hygro), P (to avoid GSA - all my tanks get it, possibly not necessary here) and trace twice a week, on different days. I don't dose C in any way. I do a water change every week of about 20% because it is stocked quite heavily - it is a guppy breeder (and cory) tank, and you know how they are. I know Tom Barr will probably say don't do any water changes, but due to the heavy stocking, I fear the NO3 will go through the roof if I don't. What should I do?
