Tough Algae even with high chlorine
Hello,
I have an IG 24,000 gallon vinyl pool with Hayward's sand filter and a 1 1/2 hp pump.
Two weeks after a massive thunder storm I had Algae bloom and I shocked the pool using 2lbs of calcium hypo chloride bags tested in the morning the chlorine was over 8 in the FAs-dpd kit k-2006. The pool did it get clear and the algae became worst in next two days so I added another 2 gallons calcium hypo chloride.
It has been two weeks and still there is residue of algae even though chlorine level is way above what I can measure with the kit, I do have tri chlor tablets in the inline chlorine feeder. *This morning I found lot more algae but chlorine level is still dark purple above the max color on the kit.*
I am ate lose down know what more I can do, the kids are eager to jump into the pool on the 4th and w have friends coming over it is going to be sad to see a green cloudy pool. What do I need to do to get it to some decent level in two days. *I will post full test results tonight but I am worried that the high chlorine level will bleach and show wrong readings. I have been brushing and running the pump almost 20 hours a day.
Help please
