Thanks for the advice. I have some stone set aside that I think will work well based on the input here. I'll take some photos when they are constructed.
I have 16 lbs of FHM coming any day now. It will be exciting to get the forage base going. Papershell crayfish will be next.
I have looked a couple times at dissolved oxygen meters and it seems that the options and price ranges are nearly endless. Does anyone have one that they think works particularly well that won't break the bank?
Thanks again.
