Returns made to Lowe's, and the stuff from Pets and Ponds got here already!
Bulkheads, gravel, and loc-line pieces. The loc-line, handily enough, fit my two pumps' outlets, so they are now pushing water around in the 50G so I can get a feel for how much power I'm dealing with. Thus far, quite turbulent in there...the losses from pushing up the return piping should give me just what I need.
Apologies for the poor pictures - BlackBerry was all I had.
Kill-a-watt measuring 91-92 watts with both pumps in operation.
Side-by-side comparison of the 50G and 30G tanks.
The pump with attached loc-line.
Blurry picture of the surface movement.
