I recently bought a 125 gallon tank, it came with a magnum 350 canister filter. It makes a awful loud sound. Like a vacuum cleaner or a blender. I left it on overnight thinking it just had air to get out. At the guys house I got it he had it running and it was quiet. Does anyone have any tips to quiet it down. Right now i just have a Penn plax 1500 on my tank and I took my marineland biowheel 350 off my 55 temporarily to help it get nitrate levels right quicker...tjat leaves my 55 with only aquatech 30-60 So the biowheel needs to go bad but i want double filtration.
