Hi!
Thanks.

Yes, I expected an algae/plankton response to increased light but the clarity is still pour and the pond is brown colored again; like coffee with cream.

I also assume fertility so am surprised the phosphate, nitrate and ammonia tests are negative.

Is there another way to measure the fertility?

I added “go clear” and “muck away” bacteria last year after I started the aerator but it didn’t seem to do anything.
