Hi everyone! Today I purchased a used 12 ft. 52 inch above ground pool. It came with a Hayward PowerFlo Matrix 1.5hp pump model #SP5500Z2 and a Hayward Crystal Clear II D.E. filter model #DE-LE-42050. From what I have researched on here, my pump is way overpowered for this size pool. Can I continue to use this pump and filter without causing problems with my pool and/or keeping it clean and balanced? Also, we are purchasing a new liner. We can use either the beaded or overlap liner. Which one is recommended and easiest to install?
