For follow up studies do the following;
1) Repeat, but have one Control pond empty of fish and report the water quality changes.
2) Run testing a longer period, for at least a year. This will act as an evaluation of the depletion rate of the absorption capacity for pH and minerals.
3) Frequent water testing both on incoming and pond water.
4) Do a cost analysis. See if this would be a profitable ...
