Hi Brad ,I am watching your every move
I wonder if it is the salt water versus fresh, I have not owned a skimmer yet. There is a huge thread on R.C. devoted to tuning the Coralifes ,they seem a bit finicky although economically priced . Our local LFS has them running and they seem O.K.
Are you going to have the bottom of your new tank drilled like the old ones ?
