Muriatic acid drying on glass?
I'm planning to use an old paintbrush to apply muriatic acid (diluted 8:1 with water) on my dry fish tank glass to remove coralline. I already tried vinegar with only some success.
After I apply the acid, what do I need to do to remove and/or neutralize it? I'm not sure what happens to the acid. Does it evaporate? I've heard I shouldn't leave the acid on the glass. Why? I've thought about dusting my glass with baking soda afterwards. Thoughts?

A good rinse should be fine. I'd be careful about leaving the acid for a long time on the glass since it might in theory etch it. Google might turn up better information, though. The acid will evaporate over time: it's a dissolved gas.

Thanks, but I'm pretty sure that muriatic acid does not etch glass.

I thought about rinsing, but my concern there is that even diluted 100:1 the muriatic acid is still pretty strong. And I don't know that I can dilute it 100:1 anyway. I'm trying to avoid filling and then draining my tank just to remove the acid, but that may be the best solution.

Some baking soda will neutralize the acid, if you prefer to use that approach.

When I overhauled my tank, I used a nice clean sharp razor blade along with some vinegar. I used a wet cloth to remove all remnant shavings.

When outside, I lay a tank down on the side that i am wanting to scrape and pour the Muratic in straight a very little bit at a time. A few bubbles later, the stuff melts off with a long-arm Kent Scraper. I have a hose running all the time - it does not take much water to dilute a few ounces of Muratic to nothing should it hit your skin or clothes for a second or two. Wear some gloves and protect your eyes... keep your mouth closed too.
You can also fill the tank with freshwater and let it sit. In a few days, the coralline will turn white and is a lot easier to scrape off. Most of my tanks are covered in a decade of Coraline and I have taken out pounds of it before after scrapong. The stuff laughs at me when I show it vinegar. |

I'm not sure what the pH of diluted muriatic acid would be, but it is a dissolved gas, and it's worth being very careful with the fumes. It's fundamentally a stronger acid than vinegar.
