Cal-Hypo during SLAM?

[sonicc]

Hello all,

I'm currently performing SLAM. I started the process with liquid chlorine and the amounts given by Pool math. I'm curious if I could use Cal-Hypo to maintain FC levels until SLAM is complete? Mainly because I have like 12x 1lb bags of cal-hypo left.

My current CH level is 120ppm

Dont do it! Excess calcium can sometimes cause cloudyness. Search for some threads on that.

Cal-hypo has a very long shelf life. Save it as a backup chlorine option.

And welcome to TFP!

I’ve read that cal hypo can cause cloudiness, but I was in your same situation about a month ago. I also had multiple bags of cal-hypo that were given to me by my pool builder. I used three bags to help get me to slam level and used liquid chlorine to maintain my Slam. I didn’t notice any cloudiness, but my algae level wasn’t bad when I started my slam either. When I started, I just had some dead algae and failed an Oclt. Not a recommendation and your mileage may vary.

Thanks all. I'll stick with liquid chlorine.
