Can FC be TOO high?

[Fool4pool]

So, based on my CYA of 40, my FC should be 5-7. We rarely use the pool during the week, so is there any downside to keeping it at 7-9 just as a precaution? Then let it drift down a little more during the weekend?

Doesn't cost any more, as I thought it through. Once you're at a level, you add the same amount if chlorine to maintain. Then on Friday, none at all, so it all evens out right?

Also, off topic a bit, but if I use the 10 mark on my test kit do I still need two scoops of powder to test? Instructions say 2 scoops, but I feel like Ive read in the forums 1 scoop is fine? Would be nice to cut that expense in half, gassle of ordering more, etc.

1 scoop is fine. 7-9 is fine too, even for swimming

The important thing is to not allow the level to go above SLAM level, nor drift below the minimum. There isn't really any harm in keeping it above the target levels, you might lose a bit extra but it's still plenty safe and swimmable if you wanted. I usually run a bit on the higher side myself.

Add enough powder so that there is still some in the bottom after mixing. That what I learned when I joined. Still do this today.
