HELP dealing with mustard algae!

[PoolDoc]

Do this:

1. Go get a cheap OTO / phenol red drops kit. Also, get a gallon of Walmart *distilled* water (NOT: "spring", "artesian", "crystal clear", etc.). Use the OTO drops to test your chlorine. Tell me what you see -- the color result may not match anything on the test block.

2. Watch ALL the Taylor instructional videos:

See if you notice any differences between their procedure and yours.

Thanks!
