CYA and Aquarite

[waterbear]

Evan,

When you say "a bit of bleach", what exactly does that mean.
I normally run my pool at 2-3 ppm FC and my spa at 3-4. If I want to bump it up for expected heavy useI raise the FC in my pool to about 5 ppm and my spa to about 6-8 ppm by using BleachCalc to see how much bleach I have to add based on my current FC level. Usually in the neighborhood of 4 cups for my pool and 2 oz for my spa.
I have been running my Aquarite at 60-80 CYA and FC 2 to 4 (awaiting Ben's kit for more precise measures). I have had several "upsets" this season already, one due to a high & long bather load, the other due to rain and junk blown into the pool.

In both cases, I recovered using bleach to shock back to clear water. But I now find myself running more on the FC 4 to 5 range to avoid getting in that situation to begin with. Which I think is OK, but is not the range recommended by Aquarite.

hope this helps. BTW, I very rarely have to do this....only if I KNOW there are going to be a lot of people in the pool or spa, such as at a party.
