Hello, pool owner for 3 years never had any problems. 30,000 gallon concrete pool with D.E Filter. is almost 20 years old. All chemicals are at ideal level except no chlorine readings. Pool water is crystal clear and no one has been in yet this season. I've been adding 4lbs of shock dichlor and maintaining chlorine tabs in skimmer. Pool water does get green when I shock (metal).

Pool stores say some phosphates. I come home with $100 in phos out products and metal out products.

1 store says just have fun and swim another says don't go in until FC has reading.

I'm haven't added anything yet that I bought cause I don't know who to trust.

Please Help

We have the same problem.... and we're buying lots of chlorine, shock, have chlorinator, etc. The pool looks great and clear... except no or extremely low chlorine reading. We are currently working on this with our 'pool guy'.

You have what is called chlorine lock. To eliminate this you need a super dosage of shock. It sounds crazy but i would throw in 6 bags of shock (based on a 16x32-18x36 gallonage) to unlock the chlorine.

Just curious. when I test my water for chlorine and it shows zero but the water stays crystal clear all the time do I need to add chlorine? I do use a swg 10 hours a day. All other levels are fine.
