You have a couple of options.
1. Backwash the filter and the pumped out waste water will drop the pool water level.
2. Siphon the excess water off with the same hose pipe you filled it with.
If it is a vinyl liner pool I would drop it as soon as I could to get it below the point where the liner attaches to the coping, You don't want the water running behind the liner if you can help it.
Thanks for the response. So it's alright if I just run the backwash for awhile to drop the water levels? That won't damage anything?
