As much as I would have liked to do the closed loop, I just did not have the funds for it now. So, I went the spray bar route. I have a powerhead that puts out 1050 gph
sitting up in the left back corner of the tank, on the overflow wall. A 4 ft piece of pvc
runs across the back to the other side.
We drilled 12 holes in in, three aimed right across to the front of the tank,
3 aimed straight down into the liverock and three aimed toward the front, bottom of the tank. The amount of crud that it moved from hidden places was amazing, but now I think we need to add more holes as the water stream is a little harsh and is creating sand pits. The only thing I do not like about this is the white pvc
stands out like a sore thumb in an all black tank.
Does anyone know of a "safe" paint that I could use to make this black?
The black pipe at the store is not rigid enough, it is more the rolled tubing.
