I cleaned my filter tonight and noticed there was a bunch of gravel/rock on the top and all in the filter.
I have been thinking I could possibly have a leak for a while now and have been looking for it, but this is the first time this has showed up.
Also, since the last time I have cleaned the filter, we have had a HUGE rain (6 inches in a few hours) and got and had the pool draining out of the over flow.
I am going to check again over the next few days.
Do you think this could be a leak or junk just washed into the over flow/pool...
