I have a low tech 55 gallon tank. By low tech I mean that I have a double t5 strip light. Very few wpg.
I have currently been dosing 1/4 tsp KNO3, 1/16 tsp KH2PO4, 1/16 tsp CSM+B once a week. I have then been doing a 40-50% water change about once every 4-6 weeks.
I've currently been battling some BBA, which I have taken care of with spot treating Excel, but I'm thinking that is probably due to low nitrates in the water? Should I up the KNO3 to 1/2 tsp a week?
Any thoughts would be greatly appreciated.
