Pink in water bowl :s

Firstly, i would like to say i'm sorry if i have put this in the wrong topic i just thought this seemed like the most fitting one :lol:
secondly, i would just like to know if anyone else has had this problem and if they had any information of what is causing the pink stuff in water bowls, if its harmful and how to prevent/get rid of it?

Thank you! (first 2 pictures is of a new bowl which has been opened and disinfected( beaphar) today, the last photo is of my water bowl my gecko has been using for 2ish years and I've noticed the pink stuff ever since cleaning it)

It could be Serratia marcescens. It is a bacteria that feeds off soap residue. I would not think it would grow in a Leopard Gecko environment though, it loves high humidity. It can cause problems in people with compromised immune systems.
It could also just be discoloration of the polymer used to make that dish. Does it set under a CHE?

Thank you for replying, one was literally brand new and just out the packet and it still has pink on so I don’t think it would have anything to do with a heat bulb. But the answer is : leopard gecko bowl no and the new one yes but not directly under it
