Hi all!!! Im looking for a reliable pool vac. The one i have is not doing so well and i was told that it is not designed for the pool i have. Im told that the pool is 13k gallons. My filtering system is Hayward c12002. I already know that the filter system is too small for the size pool i have. Im looking into buying a bigger unit. The vacuum that i have is a Hayward but i dont know the modle.
