CC is .5 ppm....algae bloom?

[aylad]

CC of 0.5 doesn't necessarily mean algae, it just means there's something in the water that the chlorine is killing. If it gets to 1.0, or if your water starts looking hazy, then I would shock the pool. If the CC isn't rising, and you're keeping your chlorine where it needs to be, then don't worry about it.

Ok, thanks for the reply.

It is just that this is my first year of actually knowing what the heck is going on with pool chemistry even though I have owned my pool for 10 years. The thing I want to know is how to spot a potential algae bloom so I can take evasive, swift action.

By the way, this site is awesome!

On a vinyl pool, the sides get slippery first.

BUT, the universal pre-algae marker is . . . you let your chlorine get low! You should assume anytime that happens, you are on the verge of an algae outbreak.

Interesting. I actually think on my pool I usually notice the bottom getting slippery first.

Could be. I wouldn't have noticed, because I've never owned a vinyl pool. It's something I learned from servicing them . . . which I rarely did from inside the pool!
