Hi Al.

Please forget what I said about installing a sand filter on the suction side. Never having had a regular filtration setup, I have absolutely no understanding of what path the water takes when pumped through them.

"As for the 1 skimmer and 1 return, not ideal but will certainly work."

This is kinda what I wanted to hear, except for "not ideal." Do you mean that a sand filter properly installed in my system might not be as efficient as my exsisting arrangement?

Thanks for the advice.
