I have just setup my 8x 2 x 2 tank but the overflows are gurgling all the time, as this is in the living room its kind of annoying, does anyone have any ideas???
Heres a pic of the overflow so you know what im on about.
carrying on the hole on the top idea couldn't you silicon a pice of pipe on above the hole so the top of this tube is always above the max water line, kind of like a snurkle (sp)
Other than that i think if you slow the flow down it might shut it up.....when u empty a bath it makes a right noise but if you cover the hole slightly it becomes quieter....
I managed to get my 8x2x2 silent by putting valves on and closing them off so only water gets sucked down. how many drains and of what size are they. also what size are the return pumps?
There are 6 outlets all with 3/4" pipe and there are 2 inlets with again 3/4" pipe, these are pumped by two Aquaclear 5000's. What are the valves, do you have a picture??
