Ok, i just got a used 135 gallon sw tank out of the local paper. Ive been wanting to upgrade from my 40g for a while now. Anyway, im having a bear of a time getting the water going into the sump to match the amount of water coming back into the tank. Also the sound of the water draining down the hob filter is loud. Is there a way to match the amount of water draining from the tank to the water coming back in?
