ok so i have a few problems i finally setup my 46 bowfront water and sand have my powerhead running and i have a hangon overflow box but my problems are...the drainhose that runs from the overflow to the sump is leaking a little bit which within a few hours can become a puddle and very unnecessary cleanup as well as my return line from sump to tank i have a 3/4 inch i believe it is hose that connects to my rio 1700 and onto the attachment that hangs into the tank. so i have those two areas slightly leaking has anyone had this problem before? and what is a safe sealent or whats the best way to go without polutting the water?
