Hi all.. I have this very aggravating noise from my overflow. :twisted: My overflow goes down from the tank into my sump and every 20 or 30 seconds or so a big air bubble goes down and makes a big gurgling sound when the bubbles hit the sump!! What can I do? I have an AGA reef ready and there standpipe kit. It didn't do it a while ago but I had a power outage about a couple of weeks ago and now it does it!! I've tried making a bigger hole in the air intake and adding a pipe at int the sump that has holes in it What else can I do? Should I make a even bigger hole..Make the existing one smaller again (silicon) ... Please help I'm going nuts here!!
Thanks
Thanks
