Started my 120 for the first time today. The water level in my sump goes up and down about 3/4 of an inch and you can hear it surge. The tank has dual returns. Is this normal or do I need to throttle back the return pump? Any advice is much appreciated as the surging is kind of annoying.

Throttle it down a bit.

you need to adjust either the pump or the over flow drains Depending on the type of drains..

I dialed down the return pump to a little over half flow and and now the water level is staying constant and the surging has stoped. Am I hurting anything by slowing down the turnover rate?

nope just means your pump is more then overflow can handle.

Since you've not provided any information on flow, hard to say whether you have too much, not enough or just right.

My Oceanic tank did that too. Dial the pump down and add a propeller pump to give extra flow. Works great now.
