I don't know what happened to your post that I moved this morning. That was weird. We've asked Ben to figure out why you couldn't see it.

At any rate, I hope you didn't add much stabilizer since you are now reporting that it is 40. That is a great level and you really don't want it higher. How did you add it? If you added it to the skimmer, can you rinse the cartridge to remove it? Or, did you broadcast it across the pool? If so, vac to waste to remove it. You really don't want it higher than 40-50. With a CYA of 40, you'll want to shock the pool up to 15ppm and try and keep it there by frequent testing and adding more bleach any time you find that it has dropped. There is no such thing as adding bleach too often when you are trying to clear a pool. I estimate your volume to be around 7000 gallons. In a pool this size, each quart of 6% bleach will add about 2ppm of chlorine. You can use that as a reference to help you figure out how much bleach to add each time you test to get back to 15ppm.

Run the pump 24/7 right now.
