Just a follow up to this post.
It has been three weeks now with Activator D.
LOTS AND LOTS of rain. Actually had to backwash to drop the level a bit because it was overflowing last week.
I have only run the pump every second or even third day for 4hrs at most.
Pool water is still close to perfect. With nothing else added at all. Only the monthly floater that has always been in the pool on the smallest setting.
Forgive the darkish spots on the bottom of the pool. Pool needs repainting. Hasn't been done in 15yrs.
Will tackle that baby in the winter.
