CYA I cannot get a good reading on that. Its over 100 even when I tried diluting with 1/2 distilled water.

Any ideas on what I can do? Pool is still a light shade of green. Still cannot see the bottom. There is lots of white sudsy looking stuff on the top of the water.
Well that's a horse of a different color. FC of 23 is not all that high for a cya of over 200. In fact, you need to get it to at LEAST 25 just to shock the pool with a CYA of 100. http://www.poolsolutions.com/gd/best...e-chart.html#a You need to consistently maintain a FC of 25 (minimum, since you don't really know your CYA level). Thank hubby for dumping all that chlorine in. Given the CYA level it was probably a good thing.

If it were me, I'd start doing a PARTIAL drain and refil. Say 25% of the water at a time. Draining all the water from an inground pool can damage it, so don't drain it all at once. Keep doing that until you get that CYA under 100. You can manage a pool with a high CYA but it will likely be a lot more difficult.

DO NOT use any more Dichlor or Trichlor (hth shock). Both of those contain CYA, and are likely the reason it's so high. It will have to be straight bleach or liquid chlorine for you.

Get more chlorine in there, dilute, be mindful of your chlorine source.
