Due to recent torrential rain, my pool developed a case of algae sufficient so that I can not see the bottom of my pool.
To attempt to correct the situation, I first adjusted the PH to 7.6. Then I superchlorinated by setting the pool calculator to chlorine level of 24, and adding triclor in the recommended amount. The next morning, the PH had dropped to 7.0. So I added soda ash sufficient to raise PH to a little above 7.6. Color of test water is between 7.6 and 7.8.
Next, I added algaecide that says it kills blue, green, black and mustard algae. ( I have had the most trouble with mustard algae.) I let the pump run the recommended number of hours after each application.
Another test for PH, tested 7.6, added more soda ash. Got it up to about 7.7 again.
I don't know what the actual chemical is, but Wal-Mart had an Aqua Chem product called "Sink and Sweep", which is a flocculant that's supposed to settle the stuff out of the water and clear the water. I added that in the recommended amount and let the pump recirculate for 2 hours like the directions said.
Went out there today to check the water after the "Sink and Sweep" had been in for 24 hours. Absolutely NO CHANGE in the water.
QUESTION: WHY DIDN'T THE "SINK AND SWEEP" WORK?
Any help would be greatly appreciated.
