I changed pool companies. I used to use the Sustain products, but now my new pool company sold me Cal Hypo shock in bags and trichlor tablets for the skimmer. I added the shock today, but I'm afraid to add the trichlor tablets just yet. Is it ok to mix the two? I'm thinking it's ok because the pool store sold it to me, but I just want to make sure.

Thanks in advance.

I LOVE this site, by the way. You guys are awesome!

Welcome to TFP!

You can add both separately to the pool, but you should never mix the full strength chemicals together outside of the pool.

As this link shows and Jason wrote, you do not want to mix Cal-Hypo and Trichlor in concentrated form outside of the pool. That also means never putting anything other than Trichlor pucks/tabs in an inline chlorinator designed for such tabs (i.e. never put Cal-Hypo in such a feeder even if there is no visible Trichlor present).
