Each spring, when everything else is in bloom, you just might think there is POLLEN in the water. Because thats exactly what mustard algae resembles. It usually starts in the shallow end, perhaps on the steps and stirs up like dusty yellow fine sand when you traverse it.
It took a bit of research but I came up with the perfect solution that has been working for me for the past several years and it goes beyond the sticky on the home page.
Here is my florida formula should i encounter Mr. Mustard.
First: Stop by your local poolsupply store and pickup either a small bag or better still a 2lb. container of NaBr(sodium bromide). At pinch-a-fanny, its a yellow container called Yellow stop. Based on pool size, of course, add a couple of capfuls per 10K gal. The trick is to mix it with chlorine or chlorox to ACTIVATE it.
Ok.. Now distribute that lovely mixture into the pool where you first noticed the algae. In the meantime, if you have a cartridge filter, be soaking it in a chlorine solution to kill it there. I use a deep bucket, immersing 1/2 of the cartridge at a time.
Chemically, for the time being anyway, you NOW have a BROMINE banked pool. That state, has effectively robbed your pool of chlorine in the conversion, SO, its time for a nice normal SHOCK. Thats it folks, works every time and doesn't return in a couple of weeks to bite you in the butt again. I think the secret is in the timing. So shock that dude right after the bromide treatment. And, don't forget to add a mild bleach to your bathing suits washwater.. or better still,if you have a nice private facility, swim buck naked....No tanlines.
