Seachem Reef Advantage Ca Stock Solution

[AllSignsPointToFish]

If I wanted to make a stock solution for adjusting calcium concentration using Seachem Reef Advantage Calcium, what kind of concentration should I shoot for. The API calcium product is around 10% calcium chloride in water (100,000 ppm). I could use a similar concentration for Seachem, but I just wanted to make sure there wasn't something special I needed to know about this product if I choose to use it in a stock solution format.

It seems that Reef Advantage Calcium is Calcium Chloride Dihydrate 100 parts with some Magnesium Chloride 5 parts and Strontium Chloride 0.5 parts. So there is nothing special, only have in mind presence of Magnesium which could be of concern if you are dosing Magnesium separately.

You can use this calculator to approximately determine how much, and use the entry for Calcium Chloride Anhydrous. Use 100,000 ppm for the desired calcium concentration and 1 ppm to start.

How do you conclude it is hydrated? The dosing amount under beginners of 5 grams raising 150 L by 12 ppm calcium fits for anhydrous.

Randy,
Was there an omitted link when you referred to a calculator? Also, I got the 10% solution part, but I'm not quite sure I understand the part about 1 ppm to start.

Yes, I forgot the calculator link. The 1 ppm is to use the calculator to determine how to make the stock solution since the calculator does not allow an entry of 0 ppm (the starting RO/DI for the stock).

Not sure how you made the solution, but 10% Seachem Reef Advantage Calcium by weight is not 100,000 ppm calcium.

I haven't made the solution yet...that's what I've been trying to figure out! Maybe I'm putting too much thought into this whole thing.

Randy, I must apologize. I'm being a little slow and dense this morning. I thought you were sending me the calculator link to determine how much to dose a stock solution but now i realize I can also use it to figure out how to make the solution itself. My bad! Thanks for all the great advice!!

You're welcome.

Good luck.

Wow, you are correct of course, I did calculations to check if it is hydrated, find that is not and wrote dihydrate It seems that i'm also slow and dense today (and may be not only today ) .
