Is the water cloudy and green or clear and green? What color green is the water?

You have plenty of CYA on hand (in stabilizer and trichlor) to reach any reasonable goal. Leave the tabs in the floater, make sure it doesn't park itself in one place against the wall - tie it out if you must. Add another pound and a half of stabilizer via the sock method. Wait a couple days after the sock is empty to test. At that point, CYA should be somewhere around 50.

By now you have killed everything chlorine is going to kill. I think it's time to let it come down. Wait for the FC to get to 5 before adding more bleach. Does your OTO comparator read to 5? Keep an eye on pH, add a little Borax if it gets below 7.0. With the chlorine below 10, perform another overnight chlorine demand test: use FAS-DPD to test FC and CC in the evening near sundown and again the next morning near sunup. Test for CH when the chlorine is below 10 as well.

Keep the filter running and brush daily.
