Hey i want to remove hard water stains on the top glass of my aquarium its limiting the light. I tried windex before and it wasnt too easy.. whats the trick if thier is any?

what I do is take a handfull of salt (wet) and then scrub the glass using my hand with the salt...sort of like exfoliating. Rub in circles. I normally do this in the bathtub to keep things wet and so I can rinse well.

Cheap and harmless to the fish.

I will give that a go.

Diluted vinegar in water scrubbed on with a old toothbrush and a scotch pad does wonders. Do a partial water change if you think too much vinegar seeped into the tank water but it should be diluted enough to be safe for fish.

If the salt dont work ill try that and stick with the bath tub

please let us know if this works with the salt.my tank has loads of these marks on it.i tried vinegar but had no luck

As soon as i get home I'm salting the mother #^@#$....please cheeck out my other post on my water...i got tons of issues out of nowhere

Vinegar

I've only every used straight vinegar on a paper towel left on the glass to sit. After a while I scrub. If it doesn't all come off then I repeat.

I use Scotch Bright pads too. I just keep things very wet and apply light pressure.
