Sump

[Piggy]

Not sure if this is the right section but I have a question. Today I shut down my tank to try and fix micro bubbles from entering the main tank. I have no idea why I have micro bubbles never did before. Any way I cleaned the skimmers pad. Turned the tank back on. When I did I have more water in the sump then I did before I turned it off. I not talking a little bit. It's about a gallon or so. So my tank won't need topped off for at least a day or more. Can someone explain why there's more water?

Did you slow your return pump down? Or did you lower the hight of the water in the skimmer. Mine has a gate vavle that adjusts the hight of the water.

Didn't touch pump. All I did was only cleaned skimmer.
