New owner of an old pool here...
I need some help determining what size filter to get. My current filter isn't doing a good job and I'd like to replace it with a new filter. I'm noticing a lot of dirt/silt on the bottom of my pool that isn't getting filtered.
Can somebody recommend what size sand/cartridge/DE filter I should get? Details are in my signature.
Also for reference here are my first test results with my new TF-100 kit:
FC - 3
CC - 0
pH - 7.7
TA - 130
CH - 350
CYA - <20
