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 ???

I'd like to see the pool store's test results, see if they confirm yours. I'd also like you to get test strips (Hach or Lamotte only) and see if they confirm it too. Normally I don't recommend strips, but I want to see if all 3 testing methods (You with drops, the pool store, and the strips) are all consistent with each other.

Ok, I ordered a TF100 kit, my old 5 way kit is worthless. Where can I get those good strips, around here they only have aquacheck ones ?the pool store is overnighting my water sample to the chemical company tomorrow , so hopefully we'll have test results by Wednesday/Thursday.
