Yea that's 2 sets, 1 60" and 1 48". I was just trying to increase the water flow. Actually only 3 in there, and 1 ain't doing much
, the 2 big ones I got off ebay a while back and never could use them cause they are designed for undergravel filter setup, I had to build a strainer to keep the critters out.
, I'm gonna take them out and put a mag 9.5 behind the rock and run 2, (maybe 4) outputs like you see in the front and that's all I'll have in it. I'm ditching the emporer 400, and the skilter (in a couple days, I bought a skimmer and have to take it back to get a little smaller one). I also have a mag 12? 1200 gph
going in the sump in a couple days, that's where I'm getting my 9.5 to place in the tank.
This is what the powerhead setup looks like from the side.
