Thank you so much for your help.. I don't know what to do now. I wish I'd come here sooner (pool was an impulse buy) - they said we can't return the filter or the chemicals.. so I'm stuck with hundreds of dollars worth of stuff that I don't need/can't use. I can't afford a new pump after all the money we've already spent.. so I guess we won't be using a pool this summer after all. The kids are going to be very sad but lesson learned. I'll have to close it up and try again next summer!

Thanks again!
