Reef Central Online Community - turbo calcium same as DIy 2part ca

Is kent turbo calcium same thing as Diy 2part calcium

Perhaps someone could post this response.

Kent turbo calcium is the anhydrous (0 waters) form whereas dow flake is dihydrous (2 waters). The anhydrous form is 94-96% calcium and the dihydrous is 79-84% calcium.

On the diy side I found at a local redimix company a 25 pound bag of Cal Chlor. Which turns out to be anhydrious 94-96%. It cost $8 per bag.

They asked my what I was using it for to which I replied adding calcium to a saltwater reef aquarium. They must have felt sorry for me as they just gave me that bag. Hard to beat free. :xd:

So IMHO the differences between kent turbo calcium and diy are:

1) price.

2) convience (easier to just go to the aquarium shop).

Does the Cal Chlor get real hot when you add water?

don't know

I have not had really hot mixes results. But then I also use recipe 2 which is a much lower concentration.

I use one of Randy's formulas (can't remember which one right now) and the calcium part uses Kent's Turbo Calcium. When I mix it I always run water over the outside of the plastic jug to be sure that it doesn't get hot enough to melt the plastic. I'm probably overreacting but it feels really hot! That only lasts for a couple of minutes but it gets *hot*.

 

[beaslbob]

Ahhhhhhhh

Mine may be like that also.

I just pour the water in and leave the room.

 

[H@rry]

You've never hung around and checked? :waaaht:

 

[beaslbob]

I think it got a little warm. But the plastic bottle was not melted or anything.

I was also using recipe 2 which is much less concentrated.

Kent turbo calcium is probably CaO (calcium oxyde/calcite), which reacts vigorously with water and generates heat. This stuff is also known as quick lime.

Bealzabub's stuff is Ca(OH)2 (calcium hydroxide/slaked lime aka pickling lime) - the hydrated form of CaO. I don't think Ca(OH)2 has such a strong exothermic reaction with water as CaO does.

Gee Tomoko At least you could spell the name right. LOL

Or perhaps beaslbob's stuff is cacl calcium chloride with the cal-chlor the anhydrious form.

 

[Tomoko Schum]

Oops, that's right. You guys use desiccant (calcium chloride) instead of pickling lime. CaCl2 heats up to about 60 degrees C (140 deg F) as it reacts with water. It's not high enough to melt most plastic containers.

SHHHHHHHHHHHHHHHH we won't tell anyone you said beaslbob is right.

Interesting. I didn't know desiccant was calcium chloride. althouth I could see how calcium chloride acts like one.

thanks.

 

[Tomoko Schum]

Yep, because it's so hygroscopic.

Did you know that they use calcium oxide for heating up the can of self-heating hot beverage?

is that an underwater microscope? :wink:

interesting. I learn so much from you.
