Raising CYA

[JTAG]

What is the preferred product for raising CYA? Thanks

Granular CYA is the standard. If you just need a little, you can use dichlor or trichlor to chlorinate for a short time, but be careful to avoid going too long.

If you search the big-box stores, look for "chlorine stabilizer." It's hard to find if you look for CYA or cyanuric acid.
