thanks Bat Man,
since the tank is going by the side of my bed, I need the space. so i decided to go w/a small overflow box instead and a fuge underneath.
Hello Leonard, thanks!
Both the inlets are going to have 1-way valves.
the spraybar and nozzle are going to be hooked up to a SCWD 'Squid' Wave machine. (Tee shaped device that oscillates flow from left to right without electricity). changed my mind about timer setup, to noisy. and the fuge...
