I purchased an 8' round Easy Set Pool for my daughters to enjoy this summer. It didn't come with a pump & filter which became quite a problem for me because keeping it clean was next to impossible even with all the chemicals. So my mom offered to upgrade us to a 10' pool with a pump & filter. So we have tried to set up this 10' pool on our concrete patio but it is just too big and won't fit. So I have a few questions: Can I use the pump & filter from the 10' pool on the 8' pool by just cutting the appropriate holes? Also does the pump have to be attached all the time or can it be attached at night when it needs to be in use? Also can you run the pump & filter when people are in the pool? Sorry for so many questions, I just want to get the most information possible so I can make a decision. Thanks for any help!
