I use this. Very simple to use and a little goes a long way. Might be something for you to look into.

Actually just bought that.

I wouldn't mind using HCl if I knew it was just that. Then when I look up the price of reagent grade HCl, this costs the same. Might as well use something "safer" for our animals.

And to be honest, do we really know what they're diluting their muriatic acid with? I guess I'd rather not play a guessing game anymore, but good to know people have success with it.

well, since water works perfectly and it’s cheaper than any other alternative, I think it’s safe to assume that they’re diluting it with water. :)

I'm sure it's just water, but what's in the water? Do we put just any water in to our tanks? :)

As a disclaimer, I have no experience or inside knowledge of industrial chemical production, so this is just an educated guess. but Hydrochloric Acid is produced by dissolving Hydrogen Chloride gas in water. For a bulk household-use solution like the Klean Strip mentioned above, my guess is that they simply take water from the municipal supply. The only caveat to that would be if other impurities (Ca, Mg, Chloramines, etc) were present in high enough concentrations to cause issues. For the reagent-grade mentioned above, they may well use RO or even DI water. I have. no idea if the swimming pool grade acid is any different from the cleaning stuff, but my guess is it probably isn't.

So there are likely more impurities in the home-depot acid than the reagent grade. You probably aren't using enough in your tank for it to matter, though.
 
I've been using the Klean Strip (and one other I cant remember off the top of my head) for two years without issue. I've had four ICPs run with nothing showing up in them. With that said, it only takes 3-4ml in 5 gallons to do what I want.

I agree, just like another poster above mentioned- we just don't know what impurities-if any-may be present in the solution. And you're right, it's only mls we are using, but who knows? I was really set on using it until some here gave me some doubts. :/

Btw... I hated Chem. Loved O Chem though!

If you want to get rid of the impurities, you can easily turn the nastiest, most horribly impure hardware store muriatic acid into extremely pure hydrochloric acid having a concentration of around 5M to 6M using the simple technique demonstrated here: .

That's so simple and brilliant - if you have the time to wait. :)
 
I want to give my recently acquired rocks an acid bath. since the rocks are very porous, how do we know if all the acid was rinsed off? What if there is some left over in the rock pores/cavities that will get into the tank?
I am new to salt water, just setting up my new tank.
Thanks.
 
Just rinse them well, let them soak a bit, several times.
Also, muriatic acid is hydrochloric acid, so you'd only be adding chloride ion anyway, which there is already an abundance of in salt water.
However there could still be impurities you want to get rid of, so good rinsing is still a good idea.

I think you’d neutralize it with baking soda.

Just a little update.... I'm not sure what he will think but I'm still using it and have been for a couple years now. It's easy to deal with, a little goes a long way and it's worked fantastic for me.

I always assumed it was sodium bisulfite (dry acid,) but the MSDS says it's a 'proprietary blend of salts.' Sounds like a secret recipe of '11 salts and acids.' I'm guessing sodium bisulfite is the main ingredient with a few other salts mixed in.

That acid is powerful stuff and is by far the best thing I have used to clean pumps and any fixtures with corraline Algae buildup. Mix it about 4 parts water to one acid. Fizzles the coraline right off!
 
I’d like to get away from muriatic acid and use this because it’s probably much safer with less fumes.?

Sure would be nice to use a simpler product with enough punch to clean and drop dKH when needed.

I’m not a big fan of vinegar anymore. It has a lot of uses, but it’s so slow. Good for many other things though. Just not a fast Coralline cleaner :-)

@Randy Holmes-Farley - thoughts??
