I've been having some issues with my sand filter blowing dirty water back into the pool.. I've changed the sand and even bought a brand new multiport valve for it. Still does it. I'm convinced (but can't substantiate) that it's the "fancy" sand that my pool store sells (big chain store.. when I went to the local pool place they were closed so i had to get from the big chain).
I don't want to take a chance on changing sand again.. (just don't feel like doing it) so I've found a used cartridge filter that I plan on putting in line after the sand filter (I know..overkill.. why not just use the cartridge filter alone..). I figure the filter will last a lot longer if it's only catching what the sand filter is letting through.
But the guy is also selling with a 2 speed hayward Pro-LX pump (1.5hp). I wasn't going to use it but then thought of the energy savings.
So my question is: the low speed is only 1/6hp.. If I'm using low speed when not running through the solar panels will that still be strong enough to push through the two filters? Or should I just keep my 1.5 HP and use it normally. Will I get a full turnover at that low speed?
Just looking for insight. My interest was in the cartridge filter (and he's including a new filter) and then turned to the pump...
Thanks a lot!
