This is the first time I have tested the ph and its way up at 9.2 I am getting ready to put in a bunch of HSB and don't want sick or dead fish.
When the pond was built we put 3 ten wheeler loads of concrete pieces in 3 piles for cover. they are big pieces but concrete all the same. Could the concrete be leaching too much lime? How long will the concrete leach lime?
Any recomendations appreciated.
The pond is about 1 acre and holds about 1.4 mil. Gal.
