Guess I won't be getting any FH. We do have snakes, turtles, birds, bugs etc. that have return to the pond sense it filled up. Maybe they will decrease the bad critters.
My PH seems to be in range but with the low alkalinity I know there is a possibility of wide swings. Am also thinking that the water test that LSUA Ag Center took was mostly rain water and of course runoff water. The water test was taken 6 days after the pond filled up. We plan to get another test done in Sept. Hopefully everything will be OK by then.
Thanks everyone for your help. I've learned a lot from reading this forum.
