I hooked up the pump and SWG to my above ground pool and have a lot of green algae. Water temp is 70%. My CYA is 50 (filtered), PH is 80+, FC is 12.5, and CC is .5.
Your article says to shock the pool but I'm not sure what "shock" corresponds to regarding FC? Is it keeping the FC at 15, or should I go higher as the CYA is 50? I know I'll need to lower the PH. I'll also need to add sand to the filter as I lost quite a bit when I emptied it out in the winter.
Btw - the SWG has a super chlorinate option and a dial that goes up to 100%. Last year it operated at about 10% to keep the FC at around 3. It can get the FC up pretty high if needed. As I only use the SWG about 4 months out of the year and remove it, I'm not concerned about using it up.
