Our in-ground pool was recently finished a few weeks ago. We just now got the equipment installed so now our water is green & brown. We tested the water and found our FC was 0 and CYA was also 0. We live in a rural area and are limited with supplies due to being out of season. We are unable to get any stabilizer so we shocked our pool. Our FC level has been high for 2 days now. Is this normal? Does shock raise your CYA? Should we Floc now and then vacuum to waste?
