Here are my pool water values:

FC: 0.1 ppm
TC: 0.3 ppm
Comb C: 0.3 ppm
pH: 7.6
Hardness 370 ppm
Alk: 97 ppm
CA: 45 ppm
Copper: 0.27 ppm
Iron: Not run
Nitrate: 7 ppm

I added a stabalizer chlorine (96%) I think...about 2.5 lbs last night...no cholorine in the pool today

I just dumped a bunch from my EZ shock bucket into the pool...didn't even flippin measure it. Probably 2 -3 lbs.

When I do add shock it is clumping on the top of the water and I don't know why.

What do I need to do to get my pool back in shape. Is it in a chlorine lock and if so, how much more do I need to add? The stabilizer is a much higher percentage of CL and I have another 2.5 pounds left of that.

When we initially opened the pool I had no chlorine problems.

Thanks for your help.
