Hey all, this will be my second season with this pool. I decided to drain/power wash it at the end of last season due to some organic staining on plaster due to the pool being neglected prior to me buying the house. Near the end of the season I ended up with a mustard bloom THAT WOULD NOT GO AWAY. I stayed at Shock levels for about 12 days, thought everything looked great and within about a week and half I ended up with mustard alae again. Between the heavy organic staining from the leaves that were left in pool the year or so prior and the mustard algae i decided to drain it. I power washed it last weekend got rid of most of the stains, noticed that i have some serious thin spots on the plaster so that will be in my future, just not in the budget this year.
So, my concern is this blasted mustard algae. What can i do prior to filling the pool to ensure that i don't reintroduce the mustard algae? the pool as two lights, that i did not take out and power wash for fear of damaging the wiring harness, it also has one main drain. Can i spray a water/bleach mix and scrub the light holes? should i do that to the entire pool? if so, do i need to rinse in fear of damaging my already aged plaster? Or do something entirely different. One last note, the light on the deep end will be a nightmare to reach, the deep end is about 10 1/2 ft deep and the light about 7 ft from the bottom so about 3 1/2 ft from the top. A ladder seems like a bad idea due to the slope of the pool, thoughts?
