Product details

The Yellow Stuff is Jack's Magic all purpose algaecide, supplied here in the 2 lb size as part number JMYELLOW2. It handles an active breakout and then keeps working as a preventative, which is the part most owners skip and then regret in August.

What it does

It goes after all types of algae breakouts rather than a single species, so it does not matter much whether the problem in the pool is green, black spotted or the stubborn yellow film that sits on the shady wall. Once the water is clear again, the same product is a highly effective preventative on a maintenance dose.

Compatibility

Safe for all pool finishes and compatible with all major pool sanitizing systems, so plaster, vinyl and fiberglass pools running chlorine, salt or an alternative sanitizer can all use it. Swimming can resume a few hours after treatment.
