As title describes, anyone know the exact weight that would yield 30 cya? Would be nice to just fill up a box with the total amount needed and then use that until it’s empty instead of trying to keep track of it daily.

Thanks
 
You asked about 30 ppm CYA in your first post.
Yes, over time. Not all at once. Manage the FC and monitor the pH when using dichlor. Once you have added enough to get to the CYA level you wish, switch to liquid chlorine.

Doing this is a pretty good idea (so long as it’s stored properly & not blindly added of course).
I think I will save my next empty dichlor container for this purpose! At the very least it gives you a cue of when to test cya after startup as to not waste reagent trying to test too early.
