It has no organisms in it . Not sure what caused the foam but that's probably not something that's desirable in a Res but I could be wrong.Im in a 55 gal res using bioag ful-power. Now it foamed up really good first two days but then the foam went away. Does that mean they died?
Temp was 70, ph 5.6, 2 air stones. Using general hydroponics trio + there additives.
