Hi! I've searched the forums, but can't find the answer. How much CYA is in Chlor Brite? I have a few 1lb bags that came with my pool, I ran out of liquid chlorine and wanted to bring my level from 6.0 to 8.0 tonight. My current CYA is about 50 and I need a little bit of stabilizer to bring it up to 65 anyways, so thought this might be a win-win? But I don't want to screw up my balanced water.

Chlor Brite is dichlor. For every 1 ppm of FC you get 1 ppm of CYA.

Do you have a SWG? CYA of 70 is not recommended for non-SWG pools.
 
I do have SWG, I see that when I updated my signature I left it out. We just set up the pool this week and I need a bit more salt before it's ready to go. It's a 2 year old Intex and to be honest, I'm not 100% sure it's still working. We only got 2 years out of our last one. I'll leave my CYA as it is, and wait until I know it is good before I add more. If the SWG is shot, I will be a chlorine girl for the rest of the season as a new SWG will have to wait until next year. 6.0 FC should be an ok level until 2 or 3 tomorrow afternoon when I get home with more LC. I'm having people over Saturday and overly paranoid for no reason that the water will go wonky in the next 36 hours.

Thanks for the response!

*editing this because I thought I quoted you @ajw22 , but I guess I needed to hit reply instead of quote

You can use PoolMath to calculate how much CYA the dichlor would add to your pool using the Effects of Adding Chemicals section.

I forgot about that feature, thanks for the reminder.

I lost 1.5 overnight, so I might have something in there after all, unless sawdust and a bunch of dead bugs could contribute to losing? Beetle looking things and bees seem to be drawn to the pool. Water is the kind of clear you don't even know is in the pool.

Picking up 6 gallons of LC and will bring it up to SLAM soon as I get home.
