Assuming alk level is good, how can boost ph? Should I try opening the canopy for a few hours?
Can someone please clarify surface agitation for me? I have a Hagen 402 pointing diagonally across the top of my 37 gal tank, and a Maxi-Jet 600 pointing straight across the bottom of the tank (rock pile in the way for diagonal).
I can see little ripples at the surface of the water. Is that enough agitation, or should I rotate the PH so that the output is pointing upwards towards the water's surface, which I assume will make bigger ripples?
