Good morning all. I have a 55gal deep substrate dirted tank with 3" sand capping with a 20gal sump filter. I have CO2 injection. I have a wave maker above diffuser to disperse co2 and on the other side of tank is another wave maker to circulate co2. This circulation does make a shimmering surface agitation. My question is should there be more agitation or no agitation for the o2/co2 balance. I've read so many websites & forums that for my size tank yes I should have more and some say no agitation. At the moment I can't get any pearling on plants. So confused.
