I have a 55 gallon planted tank and a eheim canister filter. I can't seem to keep the water free of floating and circulating particles. This is really starting to bug me. I have my suction tube on the back right corner and my spray bar shooting from right to left about a 1/2" below the water. Would another intake on the left side work? I feed only once a day. It seems to me that the intake just does not grab and pull the particles down to it. Any ideas or similar experiences, and what did you do?
