Setting up a Fluval 305
I'm finally getting around to setting up the fluval filter I have in my tank. My question is that the video says to set the intake end 3 inches above the "gravel", but I have sand. Should I set it higher, and if so how much higher, to keep sand from getting sucked up into the hose and canister?
Thanks so much for help!
I'd suggest 3-4" from the bottom ... besides, give your self some extra in the hose to the canister so you can readjust as required.
I would go with 4 inches too. I have sand in one tank with a Rena canister, the filter intake is probably 6 inches up but this is a 24-inch deep tank. In my gravel and Flourite tanks it is about 4 inches. Eheim and Rena recommend 4 inches if memory serves me.
One trick is to put a largish chunk of wood or rock close to the corner where the filter intake is positioned, a couple of inches out. This not only serves to "hide" it a bit, but it means the substrate fish are not likely to be so active in the corner as to cause the sand to billow up. I have watched the corys at feeding time with the sane, and now and then one will rapidly "jump" causing the sand yto billow up, so it seems best to prevent this in the corner with the filter intake.
The other advantage to the wood/rock in the corner is that it causes the water to flow around the object rather than directly in line to the filter intake.
Just as a follow-up, my AC70 inlets are both probably 4-6" off the bottom and I have gravel. I think there's enough subtle circulation so anything suspended will find it's way to the filter inlet. Any 'sinkers' are gonna settle where they fall. :-)

Thanks all. I like the rock idea. I have many pieces of slate, I think I'll use that. Good suggestion Bryon!
