star san question

[roundhoundbrewing]

sorry if this has been answered but i searched and found nil

Is it ok to leave star san in the bathtub. After a recent move I no longer have a nice deep basement to manage my ferm temps. I do have an extra bathroom that isn't in use with a bathtub. Would it be alright to make a star san bath to swamp cooler ferm buckets in? or will it eat away at the tub? My other option to buy plastic trash cans and make a ghetto ferm chamber. Since star san is stored in plastic, and Ive seen the early seasons of breaking bad, i was curious on whether or not the star san would be an issue.

Thanks.

Also, the reasoning of the star san is to avoid whatever muck may find its way into the tub otherwise.

I don't know about your tub's reactivity to star san. People say linoleum fairs poorly.

That said, I'd use plain water. There shouldn't be any way for it to get past the airlock into the carboy.
