CYA and Aquarite

[waterbear]

I do the same thing that Poolsean said with my Aqualogic and I have not had any problems! His advice is excellent! My CYA stays between 60 and 80 and I run the FC in my pool at around 2-3 ppm and 3-4 in my spa. If I know the pool or spa is going to get some heavy use I add a bit of bleach to boost the FC beforehand and I have yet to have had the need to shock ( based on having CC over .5 ppm)

I agree; I keep my CYA around 50, and the FC around 3-5 via the Aquarite SWG.

Evan,

When you say "a bit of bleach", what exactly does that mean. 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.

Evan,

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.

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.

When I am caring for one of the ~50 SWCG pool's we've sold, I tie the CYA to the salt at a ratio of 1:100 to get a cya level 30-40. The Goldline/ Hayward models we use indicate when more salt is required and add an appropriate amount of cya when we add the salt. If anyone is interested in reading my rant on the cya levels for salt go to the "CHINA SHOP" (off topic and general intrest area) and look for the post I started. I'll try to link it in a minute.
