How to remove the water stain in the fish tanks in homes?

[harryclean]

In fish tanks maintained in homes i saw some ash like material deposited in the glass wall of the tanks i tried to remove it with toilet cleaner but in vain. Please suggest me the correct way to clean.

Try some white vinegar.

Also, wash out the tanks really good since you used toilet bowl cleaner in them. Who knows what kind of chemicals are int them:shock:

The line is pretty much a calcium deposit. Any mild acid like vinegar should remove it. As biff said

You could also try some Lime Away or CLR (Calcium & Lime Remover) but like BJ said RINSE the tank extremely well!
