Thanks for all the replies! I have a penguin 350 hob
, and a fluval fx5 with both the outtakes pointed upward for surface agitation and it still isnt going away! Its quite a stubborn protein film! I'm feeding brine shrimp, NLS, and Dainichi. The tank isnt planted, and there is only 7 africans and a bn plec in it at the moment. Does this info help?
