No water evaporation?

[Coralgurl]

Yesterday morning, my ato alarm went off saying the water level in the sump was too high. I left it as I had adjusted the gate valve as the water in my overflow was too high and figured the evaporation would deal with it and all would settle back down. My daughter unplugged it around 11 as it was still going off. I plugged it back in last night, still too high and this morning the water level hasn't changed. I usually go through 5 gls of water a day. Should I be worried, nothing appears to be abnormal.
