My pool is balanced except maybe the Cyanuric acid, which is a little low. BUT: my chlorine levels remain low...in fact, I have 3 Slo Poke tabs in a floater, 2 in the feeder, and one in the skimmer. Still my chlorine levels remain low to nil.

So today, I put 2 gallons of liquid shock in my 25,000 gallon pool, and I just checked the Chlorine, and it's still NIL!

Where is my chlorine going?

Thanks...Neil
