Ladies and gents, I've noticed lately that I'm getting slightly cloudy water, especially after the pool has been used by the family. Numbers are all solid and I typically run 7FC/70 CYA here in Florida. I am running my SWG pretty high right now but here is the wild card...

My filter cartridge is about 6 months old (bought a knock off Hayward brand) and lately, the PSI runs up fairly quickly so I rinse, drain, and repeat. I'm wondering if the filter just needs to get swapped or maybe I'm fighting algae but it just hasn't turned emerald on me yet. Thoughts?
 
Typically we would say a quickly plugging filter is algae, but you have a Florida filter, tiny. So it could also be the case that filter is getting plugged with suncsreen, etc. Might also be what is clouding the water. Do you see a residue on the skimmer throat walls? Waterline?
