We just got our pool this spring. Up until now, it seemed like everything was going well... We left Thursday for a short trip to visit my mom and returned yesterday (Sunday) to a disgusting green swamp. I am so upset. I have no idea how to fix this.
The first thing we did was to add shock - cal-hypo - about 4 pounds I think. Nothing happened. Then I read on here to add bleach. So we did that, too. 4 large jugs from Lowes. Still, nothing.
I am worried that I have added too much chlorine and that I am going to ruin my pool. I am frustrated because I feel like I am unable to figure this out.
I tested the water again this morning, but we only have test strips... I ordered the Taylor test kit last night.
Here are my numbers as of a few hours ago...
Total Hardness: 250
Total Chlorine: 10 (strip max)
Free Chlorine: 10 (strip max)
Alkalinity: about 120
We have a 20x40 inground grecian style pool with a vinyl liner. Hayward sand filter and 1HP pump.
I guess my biggest question is how much more bleach do I need to add and how long will it take for the algae to turn from green to white like I've read about in other posts? I really, really appreciate any advice/help since I am completely clueless.
