no, havent checked #'s yet. Bought a new heavy duty algaecide 2000 from my pool supplier, said it was 100% algaecide, good stuff and he told me to put 2 chlorine tabs in. So far the water is 10 times better, light blue/green now. She doesn't like to shock until the water is stabilized. I thought different, but he has always done the trick! Using minimal chemicals/$. I vacuumed 98% to waste and thankfully mother nature has helped replenish the water i've lost. Now I probably shouldn't vacuum any more to waste as I would loose the algaecide that I put in it! Thanks for your input, I welcome more if you have it.
Great day!
