Great price! I pay nearly $20 for 5 gallons of 12%.

You can test the strength yourself. You just need to dilute the LC 10,000 times and measure it with a FAS-DPD measure just like your pool.

10,000 TIMES??????

Yeah. You add one CC (Milliliter) of LC to 10 liters of tap water--that's 5 soda-bottles full. You can usually get a marked eyedropper that has an ML marking on it--and 10 liters easily fits in a five gallon bucket.

You know, I oughta do a sticky post on testing liquid chlorine strength.

Oh, yeah--test the chlorine content of your tap water BEFORE you add the LC---you may well get a reading of 1-3ppm of FC.
