how much chlorine should I use in a pop set pool that is 6′ by 30"?
How much and how often depends on the type and strength of the chlorine. The dosage should be listed on the packaging of the chlorine. The other chemicals needed depends on any other adjustments needed. Often times this type of pool is best treated with a floater and tablets that constantly feed chlorine into the pool as the tablets dissolve. However, this is a matter of preference and the type of chlorine is not as important as dosing appropriately to keep the chlorine in the ideal range (1 to 3 ppm ideal).
