Does kalk powder lose potency if exposed to air in the container?

[TWYOUNG]

I recently saw a video by ACI Aquaculture claiming any air in a kalkwasser powder container causes it to lose potency. Do I need to be concerned that my powder comes in a rigid plastic container and as it empties it leaves more and more space for air? This seems questionable but they have apparently measured a decreased pH of kalk solution when mixed with powder from partially full containers.

Probably a good question for Randy holmes Farley, but I’d imagine humidity would make it clump which you wouldn’t want

No clumping in mine but they claimed merely allowing air in the container of powder caused the pH of their kalk mix to decrease several tenths. Now I'm questioning if I should keep it in a collapsible ziplock bag. Seems like a great way to end up inhaling kalkwasser lol!

No you will he find just keep the jar closed

The actual air in a sealed container will hav no noticeable effect on the potency. There’s just not enough CO2 in it to matter detectably.

But if air is constantly leaking in, or if it is just plain open, that will deplete it.

That makes sense to me but I believe it was Chris Meckley from ACI that felt otherwise.

While reading this, I was considering in my mind using a food vacuum sealer to just portion it out (all in a controlled environment with respirator mind you), and then I considered "What if the cops come?" lol...

Walter White would be proud of you!

I calculated and posted how much CO2 is inside a bucket and how much calcium hydroxide that might possibly deplete.

Bulk storage of calcium hydroxide?

I have access to 50lbs sacks of Mississippi lime vitacal calcium hydroxide and was wondering how I should store it? Needs to be air tight? I’m thinking of separating it into several ziplock bags and then putting in 5 gallon buckets. My thoughts were when I need to dose I can use one bag at a...

From it:


Just keep in mind that the gas that enters cannot really deplete much each time, even if every bit of the CO2 present reacted.

.
1 liter of air contains only 0.0006 grams of CO2, which can only deplete a roughly similar amount of calcium hydroxide. Adding 1 L of air every day and it all reacting would only consume 0.2 grams in a year.

Perhaps Chris owes an apology to the employee he "fired" from the job of mixing his kalk powder for letting air in the container lol!
