How often should I clean my cartridge filter and should I add anything to else to the water besides increasing chlorine to get rid of the yellow substance?
OK, I didn't see you had an SWG. The rules are a little different. But I would raise the FC to 5 minimum. Still, I'll let the experts comment on proper SWG usage.

If the yellow is pollen, I find the BEST way to fight it is a skimmer sock in the skimmer, and clean it twice a day. It catches most of it before it gets to your filter.
