So i've got a Aqua Tools cartridge filter on my pool (came with house) and i think it's time for a new one.
The pressure of the water coming out at the nozzle in the pool at the end of last season was pretty dismal, but when i closed up the pool for the winter the filter was pretty dirty.
I cleaned it (just hosed it down with water) at that time before putting it away and this is what it looks like now, kinda greyish color:
Is it time for a new one?
I found a Sta-Rite replacement for around $106 shipped.
If the current one won't suffice anymore, maybe i'll use it to open the pool in spring and then once it's up and running good i'll swap in the new one for "in season" use.
