Calcium deposits

Anyone no of a way to clean calcium deposits off of an acrylic tank? A friend is giving me an acrylic tank, but he says it has some calcium deposits on it. Is there a way to clean it without scratching it up, or should i just fuggetabotit?

i have tried but have not had much luck. i have heard vinegar works but like i said i didnt have much luck.

Alrighty then, from what he says its pretty bad so i guess i can just use it to grow some plants in or something? After i clean it and scratch it up that is, lol

just try with distilled vinegar. but be carefull because acrylic tank scratch very easy

I would leave it. The deposits will dissolve slowly in the water, my 240g acrylic was an old salt tank so it has the calcium and old coralline algae and all kinds of crud on it. I was putting cichlids in it so I just left it, took roughly a month for most all of it to go away.... But no scratches!

I agree with Fern I have a 180 RR that was a used salt tank the had a bunch of corlaline algae on it ...its slowly going away

Cool, thanks! I will just forget about the scrubbing then.

Sounds like the right idea to me.

If you do scrub use a aquarium glass cleaner(magnet) and go lightly over a period of time !

my 125 had hard water stains on it which i tried to remove. after not much luck i desided to fill it up and you could not even tell they were there. i would not worry about it but if you want to then try vinegar.

good luck.
