Great read. I have wondered about beneficial bacteria as well. More aerobic bacteria. My water has about 5 foot visibility and more green/blue with a high PH of 8.2 after 100 pounds of alum. Trying to get the PH down to 7.5 don't want to over do it so small moves. Perch are eating well and the minnows are eating well too just their colours are kinda light in colour. Water temp has creep ed up to 70 now 3/4 of an acre pond with 875000 gallon ya she is deep.

Cheers Don.
