First shock of the season, ? on my numbers

[Nori71]

So, the kids and I left for a week and hubby didn't add bleach as needed... We had algae and I shocked it 5 days ago. The water looked clear until the kids got in today (first time since shocking) and then it changed to cloudy - stirred up stuff on the bottom no doubt. I need to buy a scrub brush and really scrub, since there was still some residual "green" on one corner of the pool that the vacuum wouldn't suck up.

Anyways, today the numbers today are:
CYA - 40
FC - 7.6 (use the Taylor kit and it took 38 drops to turn from pink to clear. 1 drop=.2ppm.)
CC - .8
PH - 7.4
Alk - 110
Ca hardness (did I need this one?) - 70

These numbers look ok except for the chlorine, right? Chlorine is still too high. And today for the first time we skimmed out 2 large water bugs - I guess the back-skimmer variety? I saw them both fly into the pool and then start swimming. Is that just a coincidence or is the green that is stuck to the sides attracting them. I figured with chlorine levels like that nothing could be growing. Am I way off.

So you still see algae, correct? That means you need to follow the SLAM until you meet all 3 criteria. Full process is linked to in my signature. There's no need to test chlorine using the 25 mL sample, .5 ppm resolution is fine.

Your shock value of FC for your CYA level is 16. No, 7 isn't too high. See the chlorine/cya chart-------in you know where! (pool school)

Time to SLAM. You have failed 2 of the 3 criteria (visible algae, high CC). [slam:1g5bvx06][/slam:1g5bvx06]
