I bought a 125 gallon aquarium that came with an Eshopps HOB overflow. Not sure the exact model. It looks like it is set up correctly but it is very loud. I can turn the pump way down and it still is loud. Is there something I am missing?
Looks as if you may b missing another u tube and if you were to put a ball valve on you're export line you'd b able to adjust it so it doesn't have hardly any sound
