Angry Egg

We have a White Trash Swimming Pool here at SHG, because it gets really HOT. It's in deep shade and doesn't get over about 75F; it's under trees so it's hard to really keep clean. Shockingly, upon return from Velcro, it was kind of green and icky.

Angry Eggs are the solution. Its a yellow plastic egg filled with mysterious little chemical blocks that is tossed into the pool and instantly fills the whole thing with beer foam. In about thirty minutes the beer foam is gone and the water is remarkably improved; over the next day it gets sparkly clean and clear. It does require a lot of filter flushing, but that's a feature, not a bug, right?
