Quick stabilizer question.

That is certainly an option. And, many people (like me) do just that.

I use dichlor to add CYA because it dissolves readily. Pure CYA takes a few days to dissolve. On the other hand it takes several days to bring the CYA up with dichlor because for every 9ppm CYA you get 10ppm FC.
