Thank you for your help, advice/ expertise. I also enjoy your sense of humor about the products and me putting that scumfilled hose back into the pool I got a few good laughs.Well, those strips are junk and are commonly referred to as "guess strips", but for the moment you can use them to "guess" the FC till your kit arrives. Or if you can call around to another Walmart or whatever other stores local to you maybe there's an OTO kit somewhere you can pick up.
The chlorine you put in probably knocked a bunch of the invisible algae out of suspension. It's not dead if it's green. It's probably feeling a little squiggly though...
I wouldn't use the bags of "shock product". They are likely dichlor and will increase your CYA. Which you probably need but you don't know that for sure yet. Keep on with the liquid chlorine and expect that much of it will be consumed pretty quickly as it's working on attacking the algae. Keep the pump running, and when the strip shows you that's it's not guessing that it's 10 anymore, you can add chlorine again to get it back to 10. With the guess strips being so inaccurate it's hard to give advice to use them at all, but with the algae you're seeing, if you add a little too much over 10ppm, it won't hurt and could possibly help.
Your test kit should arrive soon since you're so close to NC.
