Phosphate testing

[Big Splash]

I just realized that I have been assuming people knew what I know, and have been failing to mention PHYSICAL BRUSHING OF THE POOL IS ESSENTIAL, regardless of which mode of chemical treatments for mustard algae you follow.

If you have mustard algae, you MUST brush!

Got ya'

I'll keep brushing just like Mamma said Works for your teeth and your pool.

Thanks Ben.
