Qt tank to frag tank?

[MacKrell]

Hi I have been keeping a qt tank up and running for abt 1.5 months, I was wondering if I can turn it into a frag tank? I have some rubble rock in there. I only did two doses of cuparmarine abt a month ago. Any advice be appreciated, thanks

If you toss the rock and sanitize the tank you could use it. I wouldn't recommend using it with the rock that's been exposed to meds.

Vinegar work good?

A vinegar bath and a good rinse should be fine. You could bleach it as well if you'd like.
