I was wondering if anyone here have a problem with water marks in their aquariums?
What can I use to clear them off?
I've scrubbed and scrubbed and they just refuse to go away! I'm getting desperate and angry; can anyone help us? Please?

Is it hard water build up? On inside? Fish in tank the only way I know is scrape with razor blade. If empty you can soak vinegar, using rag or spray to soften then scrape off.

Yeah, it's hard water build up, unfortunately. Yes, on the inside!
Ok, thanks!😀 I'll buy on of those razor blade scary things and definitely go after it! Ughhh....
