Troy,
HA usually happens when these possible conditions are not met:
1) adequate skimming (need to check if your skimmer size comparing with your tank water volume, gallons).
2) overfeeding.
3) not using ro/di water
4) not enough water flow, need to increase water circulation inside the tank and through the skimmer.
HTH,
KLee
PS: My bad. I'll remember your name forever now. Sorry about that, Troy. Cheers!
