Have you thought about draining and starting over ? If your CYA level is too high it's going to be you only choice.

pwrstrk said:I agree on draining and starting over. If you have any visible algae get it cleaned up with water and bleach after you drain.
I would like to see you use liquid chlorine, bleach to chlorinate with.
Before you drain get some stabilizer (CYA ) to have on hand. You'll have to go to pool store to get it. Buy nothing else. Just stabilizer. Also get bleach to have on hand.
Check your fill waters PH so you now if you need to adjust.
Once pool is filled
1. Add enough stabilizer to get you to 50 ppm. Put the stabilizer in a stocking and hang it in front of a return with pump running. Let pump run until it is all dissolved. Hint give it a squeeze every once in a while to help it along. Use pool math to figure out how much to add. You have no way to test this level so just assume it's there. calc.html
2. Add enough bleach to get your FC level to 3 ppm. Pour your bleach slowly in front of the return with pump running. Use that method every time you add bleach. After the stabilizer is all dissolved bring it up to 6 ppm pool-school/chlorine_cya_chart_shock. Look at this chart. You min FC level is 4 for your CYA level of 50. You can't let it fall below 4. When you add your bleach do it a night when the sun is off the pool. You can shoot for a higher level say 8. That will allow you some wiggle room so you don't fall below 4.
You will use pool math to figure out how much bleach to add daily. Take a look at it and play with so you get use to using it. Just add your pool water volume and the levels your shooting for and hit calc. calc.html
I know it may seem difficult but it's not. Any questions just ask.
