Beginning of an algae problem...

Also, use bleach instead of cal hypo or dichlor*, and continue brushing/vacuuming daily. *dichlor will increase cya and cal hypo will increase calcium hardness. And unless what you have is unblended dichlor, you shouldn't be using it at all.

Thanks for you're response. I used the cal hypo shock because my calcium levels tested extremely low and it was a convenient way to lower the amount of 'stuff' I'd have to load into my car (for my pool, shocking with bleach would take many gallons of bleach, versus a few small bags of cal hypo), plus it was on sale which made the price right.

What do you mean by 'unblended' dichlor? CYA has not been a big problem in my pool, if anything it tends to be a bit on the low side until mid-summer. Currently it is between 50-60ppm.

When we shocked it did clear up temporarily, so I will give sustained shocking a shot.

edit: Hey, I'm looking at bleach options for the pool. I'm not sure if there are any types that are not good for use in a pool? This stuff at is only a few bucks at Home Depot, but is it alright to use in a pool? Thanks.
