gagaliya said:yeah that was my original setup. spraybar all the way to left, intake all the way to right. Unfortunately that does not work for canister filters, it's making wierd noises because of the curve in the pipe so not enough water is flowing to it. The canister requires both in/out tubes to be completely straight going to/from the tank.
at least that's what i understand.
My eheim is set up that way. Spray bar on the left and intake on the right. Have it that way for 7 years now and not a single problem. You don't need the hose to be completely straight. You just don't want any kinks on it so that it restricts water flow. Air in the canister would also make for weird noises.
