My pool was flooded around about 1 week ago by a big storm. A lot of water rushed in from my lawn. It turned dirty, really dirty....After a few days of circulation, the pool turned green and cloudy. Two days ago, I decided to give it a super shock. I added 1 gallon liquid chlorine and and 5 bags of HTH super shock (1lb per bag). It has been circulating for more than 24 hours, no change at all. Normally, when my pool turned green, 2 bags of the HTH super shock can turn it back. But this time, I put in 5 bags plus a jug of liquid chlorine, and no change. So I took my water sample to the pool store. The report is attached. The chlorine level is really high, as expected. PH is 8 (high), and alkalinity is 70 (low). It is also saying "Mustard algae: Extensive". (not sure how they figured this out, how does the pool store test for mustard algae?)
The pool store suggested me to add 10 pound of baking soda first, to fix the low alkalinity problem. Then use the YellowGone product. But I am a bit confused here. For some reason, it seems that the chlorine is not working effectively. I suspect it is because of the high PH value. The pool store said the high PH is because of I put too much chlorine in there. If I add 10 pound of baking soda in there, wouldn't that make the PH even higher? Should I add muriatic acid in the pool instead? I am totally confused here. Any suggestion is appreciated.
