With a CYA of 50, you want to maintain your chlorine between 15 and 20 ppm for "shock" level. If you let it yo-yo up and down, it will take a much longer time to clear than if you consistently have it at or above 15, so testing and adding extra chlorine to bump it back up several times a day will help you get through this faster. Your TA and pH are good for right now. Take a look at your "super shock" ingredients--is it dichlor or cal-hypo? If it's dichlor, then I would stop using it for shocking and use bleach instead (keeping in mind that "shock" is something you do TO your pool, not what you do it WITH) so that your CYA doesn't rise anymore. There are certain situations in which higher CYA is beneficial but on the average, you need to keep it between 20-40 ppm because the higher the CYA gets, the higher baseline chlorine level you need to maintain to compensate and keep your pool algae-free. With a CYA of 50, you already are going to have to maintain at least 3 ppm chlorine at all times, and the higher your CYA gets, the higher that chlorine minimum goes as well.

If you'll keep it shocked, and keep your pump running, the pool WILL clear--just be patient and try to remember that it didn't get that way overnight, so fixing the problem takes time too. Before long it'll be crystal!
