Is CLR safe to use in aquariums2007-11-24 23:37:13

I know that I'd need to rinse like there's no tomorrow.but has anyone else tried this with positive results? AMMONIA.BAKINGSODA.VINIGER AREN'T WORKING.

Answers:

CLR (which is used to clean tubs and showers) contains the following ingredients: Water, Glycolic, Sulfamic, Citric Acids, Surfactants. So, water, acids, and surfactants (which are basically detergents). You could probably use it on an empty aquarium if you rinsed it exceptionally well afterwards, as you noted. I would not use it on an acylic tank, however, but a glass tank it should be okay.

I do have to ask, why are you considering using it? If you are trying to remove hard water deposits from an old aquarium you can use a solution of white vinegar and water which is safer and cheaper. I know you said you tried vinegar - did you let it soak for a few hours?

I would think so, if you rinse it out really well.

Call a pet store and ask them.

Absolutely no CLR! If you have a salt or mineral buildup on your glass, try using salt as an abrasive to remove it. No chemicals. If your tank is made of plexiglass.no salt, it will scratch it! Try a product especially make to clean plexiglass.

I can tell you positively that the chemicals (CLR) will be absorbed by the slate and render the tank useless for fish, reptiles, amphibians or invertebrates.
