Pool water is sparkling clean.
This am test results:
FC - 6
PH - 7.8 (I'll do my usual two week dose when the timer kicks the pump on this morning)
I cycle the pump for six hours at 10 am. So why are there small light green patches of what look like algae that are in the footprints in the floor and cove area at the end furthest from the return? And yes, I tested the water there and the CL is still 6.
