I drained my pool about 3 weeks ago to get rid of excessively CYA levels, leak repair, and acid wash the plaster. Fresh water has been back in about 3 weeks. Water is nice and clear but with a mild algae bloom on walls pool floor. Pool is 35,000 gallons, Whisperflo 2 speed 1.5HP, sand filter and Polaris 360 with booster (and a Pentair Offline Chlorine Injector that is not operating (pucks sit for a long period of time before dissolving)- I think model is Rainbow 320?)
Test Results from 11:30 am this morning are as follows:
CYA= Somewhere less than 30ppm. I am using the Leslie Residential Complete Kit and I filled the test tube all the way to the top and could still see the black dot at the bottom. The top reading on the tube was 30ppm, thus, actual CYA must be somewhere less than that.
I have not adopted BBB yet, but then again, this may be a good opportunity to do so due to the fact it is new water. Thoughts would be greatly appreciated. Thanks-
