Algae won't go away after shocking

[Patrick_B]

Thanks! I'm a little apprehensive to spend $68 on a test kit. I've been spending so much money trying to fix this problem! Will it last me a long time?

Also, I looked at the chart and it says I will need my FC to be 20 to shock. Mine was only at 5. This worries me that going this high will ruin my liner. (Sorry I'm a newbie!) I use a chlorinater with tablets. It recommends I use bleach or liquid chlorine instead. How much will it take to increase that much?

Thank you for your help!!

If you keep going back to the same place, it's going to cost you a lot more, but don't worry about the bleach hurting your pool in any way. Too much of any form of chlorine could do that if it were over fed. As for what you will need to shock, it's really impossible to say without some solid test numbers.
