Hi Mastamoon;

I didn't know that what you were using was bad -- I just didn't know if it was good. So much goop is blended in these days, in order to lower the manufacturer's costs AND raise the price, it's hard for us to know just what you are putting into your pool, or what effect it will have.

If the pool is clearing that's very good, and indicates that you do not have a super-high stabilizer level, or a chlorine resistant strain of algae. But, the advice I gave you is still correct, especially the bit about testing pH with a 50:50 pool water / distilled water mix.

And, do keep your chlorine in the orangish yellow range till the algae is ALL gone.

Best wishes,
