I have a bit of an issue that I need help with. I woke up this morning and noticed my ATO tank was empty and my chamber with my return pipe was empty as well. So, I quickly filled up the ATO and chamber. As my return pump entered water into the display - it started to overflow. (drain pipe not flowing correctly), so i'm assuming my drain pipe is clogged? So how do i fix this drain (PVC) pipe without taking it apart? There isn't alot of room to work where the return and drain pipe are located.
Or could it be something else? I currently have the return pump turned off, trying to figure out how to fix this.
This is a 90 gallon reef ready tank with the standard, 1 drain and 1 return pipe.
