Hi all,
Trying to clean the cover glasses on aquarium, they are cover in hard water deposits from keeping African cichlids.
I have tried vinegar and elbow grease to no avail, even leaving to soak overnight.
Has anyone used anything that has got rid of these marks?
The old tank used to be dosed with Epsom salt and bicarb for buffering the hardness. That could be what's causing the marks... can anybody help?
