  • An absolute must for every pool closing season
These are a must for closing our pool every winter. We open the pool in May and it’s clear every time

  • Not impressed
Put this in the pool a week ago when we closed it up. In ground, 35,000 gallon. Just pulled a corner of the cover up and there it was, empty. For the money, not worth it.
