Adding CYA

[aylad]

No, I think I got the last one at TaylorTechnologies.com. I have also bought it in the store at Leslie's, when I'm in a pinch

Leslie's is where I usually get the R-0014 since my preferred online vendor also doesn't carry it.

I wanted to add a 'heads up' in reference to adding CYA slowly via the skimmer. While it will get transported into the filter eventually it first sits in the pump pot for a while. This might be disconcerting to someone who hasn't used the skimmer method previously.

It takes about 20 minutes for my water flow to clear approximately 1 pound CYA out of the pump pot. I have a 2-speed pump and set it on 'high' when I make this addition.

Just file it away in your 'Oh yeah, didn't I read about this?' memory.

I have bought on-line from Amato and Taylor directly. Very happy with both. Fast shipping and easy to deal with. Amato has better prices. Riddle me that? Both got me my product in a few days. Amato charged $11.00 for shipping, Taylor shipped free (built-in). Even considering this, Amato was still a good bit cheaper.

LIke I said, add it SLOWLY! I put about a half cup at a time in and wait a bit before adding more.

I added CYA by the sock method. I would like to know what the acceptable chemical balances would be for my type of pool;

I have a gunite IG 14 x 28 approx 17500 gals:

My latest readings:

Chlorine 1
Ph 7.2
Alk 100
CH 160
CYA Just added and am waiting before testing.

My Ph, Alk, CH have dropped alittle from a few days ago. Any advice on what levels to achieve and maintain? Thanks much!

I can't believe there isn't a sticky on recommended levels (I looked but couldn't locate one)!

Unless there was a lot of water lost from your pool this week the drop in Calcium Hardness is probably due to testing variability.

Free Chlorine (FC) should be aligned to your target/actual CYA level. See this chart or target a minimum FC of 5% of CYA (SWG) or 8% of CYA (no SWG). For example, if you have added enough CYA to achieve a 50 PPM level, keep Free Chlorine at or above 2.5 (if pool is chlorinated by SWG or liquid chlorine automation), 4 PPM otherwise.

So, chlorine appears to be too low. pH is within acceptable range, TA is fine, CH could probably come up a bit. I like to use the Pool Calculator to determine the saturation index when trying to balance Alkalinity, calcium hardness, pH, salt etc. It will also display recommended levels if you enter the type of pool you have.
