So I need that Kem-Tek Stabilizer from Amazon or head down to the pool store and look for some stabilizer without breaking the bank.. If I go to the pool store, im looking for "100% Cyanuric Acid". What CYA level is 'ideal'? 50-60ish? According to bleach calc, if my current is less than 20, probably close to 10 since there is some in there, as the test was slightly cloudy.. I would need 3lbs and 15oz to get to 40-50 est. Is there any reason not to use liquid stabilizer (minus cost)?

If you have brushed your entire pool, and have no more green anywhere, you can drop your chlorine levels back to the 1 - 3 ppm range. I'd recommend adding a single 96oz jug in the evening, for max effect, and then maybe 1/3 of a jug before swimming.

However, you need to get some stabilizer in there. How do you want to do that? If you have access to a Sams Club, a very easy way is to buy their 24lb pack of PoolBrand dichlor shock -- on your pool, the whole package equals 160 ppm chlorine, and about 140 ppm stabilizer. But, the sealed bags will keep till next year. A good dose for your pool would be 1/3 - 1/2 bag in the evening. Each bag will add about 13 ppm chlorine and about 12 ppm stabilizer. Sams is selling those packs for a little more than $2/lb, at least in my area.

If you can't do that, and need to get it from Amazon, here's the link:
Kem-Tek Stabilizer 4lbs
If you get granular stabilizer, put it in an old sock, and hang it in front of the pool return.
