Kalkwasser

[Winchester]

I have access to Calcium Hydroxide, he also called it Hydrated Lime. The spec's where as follows:

Calcium Hydroxide 73.8%
Silica Oxide 0.9%
Magnesium Oxide 0.7%
Sulphur Oxide 0.4%
Co2 24.0%
Lab Grade

so can anyone tell me is this the same as Kalkwasser and is it going to be safe to use in my Reef Tank?
Any information would be great

As I know Calcium-hydroxide [Ca(OH)2] is called kalkwasser. Here at Europe it's 99% clear... I wouldn't use that...

Silica Oxide - [SiO2]? is food for algaee....

Yup, that should be perfectly safe. And I doubt that little trace amount of silica is going to cause any problems.

Everyone likes to save money, I was scared about using it. But Iza NZ says I will be ok. If anyone esle has a option please feel free to let me know. Btw thanks for he reply Iza NZ.

That material is largely calcium carbonate (note the 24% CO2), and I wouldn't use it to make limewater.

Save money... Picklilng Lime.

I think it is the same. I use aragaMILK to take the place of that kalk things.

Kent Kalkwasser is not that expensive, and you know exactly what you are getting.

Since I've used the Kent Kalk, my calcium is about 500 in my 75 gallon reef. It's hard to beat the old tried and true.

I think it is the same. I use aragaMILK to take the place of that kalk things.

I do not think that calcium carbonate is a useful additive. Aragamight, Aragmilk, and Kent Liquid Reactor essentially just fine sand that mostly ends up not dissolving in marine aqauria:
