Raw Calcium Question

[Luke.]

Any of these ok to use in our reef tank ?

The last is the commonly used calcium chloride and produces a bit of heat when water is added. Being pelleted it’s likely very similar as to what’s purchased in bulk at reefsupplies. It works well. The other options are hydrous calcium chloride and won’t produce heat. If they are pure enough all can be used without issues. Seeing as they are lab grade, I wouldn’t hesitate.

expect a slight pink coloration in all of the above. This is completely normal.

The last one on that list was the one I was going to use I just thought it was pricey and the others may be cheaper just wasn’t sure if it would work for my 2 part or not ?

They will all work.

You can use any of them but when you start to calculate concentration of the dosing solution or amount to "spike" the system, you have to factor in the water attached or your numbers will come out lower than actual by about 5-10%.
