despite multiple shock treatments (both chlorine and non-chlorine), treatments with algaecide, phosphate removal and dry acid, my pool will not hold chlorine. The water looks spectacularly clear. The pool supply people seem to be at a loss to diagnose. Can you help?

You'll need to get a water test and find out the stabilizer level. Let's say your stabilizer level is at 100 and the ideal level is 50. You'd have to drain and replace 50% of the water.

Amusingly enough, that was my guess. The document doesn't suggest a specific amount of water (1/4, 1/3, 1/2, etc...) to drain. I can use the pump to drain about four inches (from a 30' x 4' circular above ground pool). I'm guessing that I need to do more than that. If I'm doing my math correctly and start with a 48" tall pool, I'd need to drain about 1' to be at 25% and 16" to be at 1/3. I don't want to keep emptying and refilling, so I'm interested in knowing what level of draining I should target.

In my experience, draining some water and refilling is the quickest way to resolve chlorine lock.

I saw that report which lists four different approaches. Is there a "best approach" of the four?

Hello Gaddison - You may have "Chlorine Lock". This normally occurs when the stabilizer level gets too high. Check out our guide titled "How To Break Chlorine Lock".
