Chlorine Lock ????

[poolrescue30]

I did put in the 15 lbs of calcium hypo shock Friday at 7:00 pm, I know Carl you said chlorine is chlorine, but this was the advice of the pool store's chemical supplier who also produces his LC. I tested the water tonight at 11:00pm and it shows .5 FCL and .5 CC, I don't know if we are getting anywhere ??? I will take a sample to test by the pool store and we are also sending a sample to the chemical supplier as well. I'm at my wits end and don't know if I should just drain the pool halfway, or the whole damn thing OR do we just continue with a clean ,clear (when the calcium goes down ) algae free pool, with a CC problem and treat it with some bleach every couple of days and swim as nothing happened ???
