Just as Flo Grow says my friend.Merry x-mas FG and thread OPThe water should be right at the bottom of the pot.
Either scimming across the bottom or no more than a 1/4 - 1/2 inch in the water.
Unless ur doing RDWC with sprayers.
Ok I am taking all of your advice and raising the water level and I will post the results.
Thanks for everyone's help.
