Tank: 120G 24x24x48 inches
Center overlow w/sump.
I replaced my loc-lines + random flow generators with 2 spray loops made from the black furniture grade PVC.


Why loops? when doing drip-line irrigation in various gardens I learned that a loop delivers better pressure consistency to all the output spouts. It makes sense, there's no "end of the line" where pressure falls off dramatically.
I used Ts and stubs of pipe to close the loop at the bottom because elbows and Ts were only sold in packs of 10 and this way I only needed one pack.
Each loop has a total of 11 holes at 3/16 inch. Seems to flow pretty good and the pump is working a lot less hard, i had to dial it back after the backup drain started sloshing. Will less backpressure mean poor performance with my new CO2 reactor? have not tested yet...
I loved the idea of the random flow generators but they really work better for a peninsula style setup.
