Had the pool covered with a solor cover and the vs pump only on for four hours a days with a salt cell. Came home after being away for three weeks and uncovered part of the pool and spa and it looked loke some green stuff was taking over the pool. The prior weather was cooler and we were not using the pool now we wanted to use the pool and need to get rid of this stuff. Took the clear solar cover off and brushed down all the sides including the spa. Used 5 gallons of 8.2% bleach, (I do not think that was enough). Let it run for a couple of days, Cleaned out the filter. Brought the pH down to 7.4-7.2, TA 300, CYA 40-50, Hardness about 200. The chlorine was runnin low for the winter. Increased the run time on the pump to 9 hours at 2200 rpm. The pool temperture is about 78+, this morning 82.
Today checked the pH and it was up past 8.0. added 3/4 gallon acid 32% stuff from the pool store. (HD and Lowe's is only half as strong)
Hopefully it should bring the Ph back to 7.2-7.4. The pool store said that salt water pools does this to the pH levels, any truth in that?
I need to shock it again. How many gallons of bleach do I need to use and what strenght bleach. 8% or 10%
Attached are my green pictures before any corrections, green walls and bottom, but clear water.
Any help to control this is more than welcome.
