Aloha, All, How do I get on top of the chlorine levels? I bought the blue floater at Home Depot and put in 3" tablets but some days chlorine is very low according to the vial test kit, so I shock the pool with 1/2# bag or so. The next day it may be too much chlorine and I pull the floater out for a day and the next day the chlorine is low again. Pool gets very little use, so the load does not vary much. Should I get a chlorinator or just keep working until I figure the floater out? Here is a photo of my pool made from a 20' steel storage container. It has a Jacuzzi on one end. And is located right off my back porch.
