T cell 40 tests ok but not making chlorine??

[PoolDoc]

The K2006 or 2006C goes up to 50 ppm; that's one of the main reasons we recommend it. Another is that Taylor's phenol red continues to give fairly accurate pH test results up to 10 or 15 ppm of chlorine, vs 3 - 4 ppm chlorine from many other blends. If you already have a Taylor K2005, you can get *just* the FAS-DPD chlorine test; I think it's a K-1515.

Anyhow, links to Amazon for these items are found on the Amazon kit page in my signature. One caution: the Amazon seller, Amato Industries seems to be pretty consistently the cheapest and also more reliable than some others. We've seen some problems with other sellers shipping K2005 kits instead of K2006 models. Amato seems to restock in a day or two (they are located VERY close to Taylor), so if the link shows another seller, wait a day.

Thanks everyone, I,ll start with shocking and brushing and hopefully get my pool back. Do you think that the algae has been causing the drop in Chlorine? So far my equipment has tested ok and I've never had scale on the SWG plates.

Absolutely the drop in chlorine is due to the algae. That means it is doing what it is supposed to do ---- kill algae!

I suspect you may have some chlorine generation but it is being totally consumed by the algae. Get the mess cleaned up and stabilized with bleach and then watch for output from the generator. I'd start at 100% for the first couple of days after you get stabilized and then see if you can back it off
if the chlorine levels are good.
