I am building a 60 gallon tank. It was filled with water this morning. I started a sponge filter on one end of the 4 foot wide tank and an Aqua Clear 110 filter on the other end. Although the intake apparatus appears to be well positioned in the filter, I find the flow rate to be too strong. I have adjusted the flow rate as directed in the instructions, but it appears to make only minimal difference in the strength of the flow. Anybody with experience with these filters?
