Removing Lime or Calcium Deposits


Hi

I'm planning on starting a 29 gallon, and cleaned out an old one. Looks pretty clean but there is a lot of lime or calcium deposits toward the top. Has anyone else had this problem? It's very unsightly and I need a way to remove it, or else I'll need to by another brand new tank... Any suggestions?

I use vinegar. There are heavy duty cleaners that you can use when you have an empty tank (CLR or something like that). Some use a lemon. Others use razor blades. Or Windex. Or alcohol. Just depends how bad it is and what you have handy.

+1 for vinegar. I found an old Aquaclear filter at a yard sale that was absolutely encrusted with calcium depsoits. A little vinegar fixed it right up.

Wow... Didn't know vinegar could be used to clean it... Will test this out when I have the time!

Looks like a good cheap alternative vs. the commericial products like "Lime Off". Crossing my fingers that it works!

Well... After scrubbing and scraping for an hour and a half straight, I've decided to just by a new 29 gallon tank....

I used vinegar (two types) and a razor blade and had "some" success, but not as much as I wanted. I filled the tank up and I can still see the calcium deposits when I look closely. If I plan to spend $300+ on the tank, I want to have a perfect tank, so I minus well get a new tank. ARGH

I think you are doing the right thing. Sometimes glass seems to go "blind". I got a used 43gal tank that was home to a dragon lizard and stood outside in the yard for a long time. I can't get it back to like-new shape, the glass seems to be permanently stained.
But for the weekly cleaning of glass surfaces, Vinegar works great.

I bought a second hand tank that was heavily encrusted with calcium deposits. I used a paint scraper and got rid of all of it without leaving any scratches. I was pretty rough with it too.

Hope that helps

This stuff works so great it's unbelievable. I tried it after getting sick of vinegar not working too well.

Use the glass cleaner first then the rydyt2 second.

Sometimes they don't come with atomizers ("sprayers"). So you really need to find some if they don't.

Hmmm... I might give this I try if I can find a place that sells the stuff. Big Al's unfortunately doesn't ship to Hawaii, any other stores in mind?

I've just removed a hood to finally move to an open top tank and there is a lot of calcium deposits on the glass that was hidden by the hood. It does scrape off but it's difficult to get it all off.

Most of what I need to remove is on the inside lip of the aquarium. The aquarium is fully setup and I have no intention of breaking it down to clean this.

So what do you use that is also safe for the fish and fauna?

1. Old empty tanks, need razor blades & days of repetitive & methodical scrapping.
Vinegar will definitely not work with this 'white' glass situation.
Have not tried the above chemicals... (links). (in Australia you see)
2. If you have the above situation as an occurance about the waterline in an active
tank, BAD LUCK!. You'll cry... sob... curse etc...
Break the tank down, remove fish, plants gravel - EVERYTHING!
Go to item Number 1. (#@$!)

Buy a new tank I suppose $$$$$$$$$$ =(

My office coffee pot is used more to heat up water for my current hot drink of choice, southafrican red tea. The pot started to get a mineral deposit from the hot water with no acidity from coffee, I don't brew the tea in the pot, it's just hot water.

I tried a quick fix, seltzer water.

The deposit was gone in seconds after I poured in a little of the seltzer. Would one of you with an aquarium calcium deposit mind trying this out to see if it works on that kind of deposit too? I don't have any calcium deposits at home to try it on.

What do you mean by selzer water? Doing a search it looks like its basically carbonated bottled water?

Exactly. I used it on the coffee pot on a whim, knowing how acidic sodas are in general. It took the deposit right off, gone, clean, my eyes bugged out.

If it works on calcium deposits on aquarium glass we have a safe way to clean them up, adding a little water with carbon dioxide in it. Don't use Tonic water, that has quinine and sodium in it. Don't use Club Soda, it has sodium in it. Don't use 'flavored' seltzer, it has sugar and friut juice in it.
