Need some help choosing the best size cartridge filter for my pool. I have a 18,000 gallon screened in pool with a caretaker 99 (ugh..) system. I am removing the outdated and underpowered 3/4HP pump and DE filter that was in there.
So far I have selected a SP2302VSP from Hayward. It is a 1.5HP variable speed pump. Based off everything I have read it looks like a 90sf will carry the system.
What do you think?
