Hi. I have a problem in my tank. My tank has a glass cover i had it for 1 year and a half. There some brown thing on the glass from the top, i mean on the cover, there is alot , they are from the inside and outside. Is there any sort of spray or liquid to put on them to remove them. Plz they look ugly.
The brown stuff is either algae or some stain accumulated over time. This is why it's important to clean your cover regularly, much like cleaning your filter. Otherwise, the stuff may accumulate so much that it's hard to remove it later. Try cleaning it with warm water first, and see if it will come off.
