    Like the title states, I decided to break down the recommended dosing instructions per brand to help me (and possibly others) when deciding on what supplements to use and dose (and how much if switching). Also Randy, please feel free to correct me if I'm wrong on any of this.

    I decided to do this after spending a good amount of time looking into all three and I wanted to have all three laid out in a simple comparison for easy dosing instructions. So hopefully this helps someone out, like it helped me.

    I did this by simply using the Red Sea Reef Care Program's (RCP) Reef Foundation ABC supplements and their dosing instructions, and then comparing it to the calculators on BRS, and the Reef Chemistry Calculator.

    Red Sea RCP vs BRS vs ESV B-Ionic dosing breakdown:

    Red Sea RCP
    Reef Foundation A: 1ml will raise the Ca level of 100 liters (25 gal) by 2ppm
    Reef Foundation B: 1ml will raise the Alk level of 100 liters (25 gal) by (0.1dKH)
    Reef Foundation C: 1ml will raise the Mg level of 100 liters (25 gal) by 1ppm.

    BRS 2 part
    2 part Calcium Solution: 5.1 ml will raise the Ca level of 100 liters (25 gal) by 2ppm
    2 part Alkalinity Solution (Soda Ash): 1.7 ml will raise the Alk level of 100 liters (25 gal) by (0.1dKH)
    BRS Magnesium Mix Solution: 2 ml will raise the Mg level of 100 liters (25 gal) by 1ppm.

    ESV B-Ionic
    E.S.V. B-Ionic Calcium Buffer System Part 2 (Ca): 3.1 ml will raise the Ca level of 100 liters (25 gal) by 2ppm
    E.S.V. B-Ionic Calcium Buffer System Part 1 (Alk): 1.1 ml will raise the Alk level of 100 liters (25 gal) by (0.1dKH)
    E.S.V. B-Ionic Magnesium: 2.5 ml will raise the Mg level of 100 liters (25 gal) by 1ppm.


    I hope that helps!

    Great guide. Just a small note to add that with Red Sea Foundation B *powder* mix, the stock solution is roughly 1/3 strength of the bottled pre-mixed liquid so only lifts alkalinity by 0.034dkh per 1ml solution. Foundation A/C appear to be the same strength whether using powder or liquid.

    Also it could be worth mentioning that red sea calcium also has strontium and Barium... ESV should also have some trace elements but I'm not sure...

    That's a good point. I stopped dosing those when I started using Foundation A.

    Just to clarify a bit...

    ESV two part has magnesium in it, and probably about as much as my DIY (BRS) when my DIY magnesium part is used as recommended. So their magnesium supplement would be used in a different way to my DIY.

    Thanks for pointing that out, I forgot to put that in my dosing conversion. Chances are you won't really need to dose Magnesium (only occasionally for periodic adjustments) as its already in there. ESV also has trace elements in added, so if you try to avoid water changes, chances are you'll want to eventually add those back in or dose them after some ICP testing if you are noticing anything dropping.

    The $$ comparison would be good to add. From what you posted it certainly seems like Reef Foundation A/B/C requires the lowest doses by volume. It's late, almost time for bed, but I'll make a start at it:

    ESV 2-gallon package (1G Ca, 1G Alk) = $34 ($17/G each)
    5000mL Reef Foundation A, B, or C = $85 ($64.39/G each)

    The Red Sea is 3.78x the cost of ESV by volume, but 1ml of the RF A (Ca/Sr) does as much as 3.1ml of the ESV Ca. Alk is close to even & Mg is 2.5x more potent. ESV seems to come out cheaper on paper. Especially if you need to buy a lot - the "8-gallon package" brings the cost per gallon down to $11.25. How much cheaper is the Red Sea powder? I'm not sure how much liquid volume the 1Kg jar makes after mixing.

    Also, If you mix Red Sea Foundation C into a solution stock at the recommended amounts, the Mg will fall out of the solution. I actually recommend the ESV Bionic. It is premixed. It is about the same price as 1kg of Foundation C Dry Mix. Also, the product does not need to be constantly stirred. My experience is derived from Foundation C dry product. I do not have experience with the BRS product. If anyone does please chime in.
