Need help

I went take a night shower and went down look at my fish tank and every thimthere start to turn purple even the glass and equipment
Hard to scrap out. Is that good or bad?

Did you medicate tank or have a sea apple or sea hare which may have inked?
It is obvious something has released into tank

Do immediate water change and add good grade carbon or chemiPure elite

Are you talking about hard purple growth on surfaces?
If so, that's coralline algae, great stuff, sign of good water quality.

That'd be pretty gradual growth though. Certainly longer than a shower.

Are the lights on a schedule and OP came down late at night (after shower) to see tank ramping down under almost all blue when coraline is most evident?
