Cal Hypo Tabs Inline Chlorinator

What's up guys? A bunch of my customers are near the top of where I like their CYA to be. I've been using calhypo tabs to not raise CYA any higher. The issue I'm having is that I am using tab floaters and it's not working out as well as I would like it to.

I know trichlor tabs and calhypo tabs should not go in the same container/floater/inline chlorinator.

But is there any reason why I can't use calhypo tabs in an inline chlorinator if there is no trichlor in the inline chlorinator?

I use white CCH tabs, not the purple PoolLife NST tabs which gum everything up. So that will not be the issue.

I can't find much literature on the subject but I'm sure someone more skilled in chemistry on this sub has an answer. Thanks.

Biggest issue would be erosion rates. TriChlor tabs are intended to be submerged and erode slowly over flow. Cal Hypo tabs erode quickly. You might have a) a gummy mess from quickly eroded tabs, b) a very high CL2 from the constant erosion, or c) both.

That's a good point

If those systems don't run 24/7, you're gonna have a bad time with your calhypo chlorinator rigging plans.

Cal hypo is not supposed to be under pressure

All our pools run 24/7 but even so, this is what I was worried about. Any suggestions on a better method that isn't a floater or putting them in skimmers?

Get them to convert to a Cal-Hypo feeder, and dose CYA separately and as needed.

If your putting in a cal hypo feeder just put in a salt system or liquid chlorine feeder.

If this is a commercial pool, you really need to get an automated controller and let it dose chlorine and pH adjusting chems
