How much of chlorinating liquid do I put in my 14-48 pool?
It depends on the concentration of the chemical and gallons in the pool. Consult the packaging as the dosage should be listed there. It will also depend on the bather load, rain, etc. that introduces contaminants to the pool. The best thing would be to test the water 2 -3 times a week to make sure you have 1 to 3 ppm of chlorine present.
