New to the forum but not the hobby. Spent a lot of time in fresh water (at one time 140 cichlid tanks). Have had a 75 gallon reef running for a few years. Healthy tank but is loud. I am in search of quiet parts. Pump in sump being changed to an eheim. Have changed fans to computer (low speed and quiet). Is there a way to quiet the over all cabinet w/out raising the heat to much. If so what is the product and how. Sorry if I am in the wrong spot with this post. Thanks in advance
