Hi, I've used this site to manage my pool for a while but have never posted. I really appreciate your no-nonsense / inexpensive approach to pool management. I have a 24' round above ground pool. Had it about 15 years. Last week my test strips fooled me and I added some stabilizer, which evidently I didn't need. Now I have a green, cloudy pool with 5 -10 ppm FC. Question is, if I lower my pool level and refill with fresh water and then still have a good FC level, what do I do? Do I wait for it to clear up on it's own or do I shock?
