Hello
I was calling the suction tube leading to my canister filter a "drop tube"
The suction tube is about 7 or 8 inches from the gravel, in a 2 foot deep tank.
I just wondered if I should extend this more?
I also have a Penguin power head that I was considering to move more water around, But there is a current in the tank already.
I don't think I want anymore current, Or the little guys won't be able to relax.
Thanks
Adam
