I got the retest results back and I am still baffled, particularly with almost an 9x decrease in the amount of potassium. Makes no sense to me. To make matters worse, I bought a couple of bottles of those water test strips for pools and the test strips show the alkalinity in the 80-120 range....and the trout are still aggressively feeding and from all I have read, they shouldn't be if the alkalinity is as low as the lab results show.
