The sump is filling faster than the the pump can empty it
Ok... i've had my aquarium (240l) running for about 2 months and decided to add a sump. Built the sump (25l) and added it today.
The sump is filling faster than the the pump can empty it! I'm no plumber and have no idea where to start. Can anyone help?!
I really don't have much to add but I am curious, what kind of pump do you have on there now? What kind of piping? I have heard of people putting too small of return piping on and that was restricting the pump.
