overflow question

[Brucewrs]

I have an AGA210 with dual mega overflows. When I look behind the tank the water level on one is steady but the other keeps surging up and down a little..Is that normal?

[Brucewrs]

I never really paid attention to the back so not sure how long it has been doing this.I just added a "t" fitting so water flows into both holes in my wet dry.I have a pro clear 400 and only had one hose hooked up because the other overflow is dumping into my fuge.I noticed that half of the bioballs were getting wet so I made a "t" so the water dumps into both holes.Less restriction too..??????




This is what I am talking about.The first pic the hose was down.I put it up some in the second pic but it is still surging.???I cant put it straight up because I clean the filter pad every other day.The top wont come off then.

This is what I had and only one side was getting wet.

This is where my other overflow is going.Then it drains into the sump of the wetdry and 2 1560gph pumps,pump the water back into the tank.
