Red sea trace elements and 2 part math.

Robbie_b · Jul 17, 2020

So based on my recent view on brs video on red sea trace elements and 2 part dosing. Its for every 51.1 ml u dose 1 ml of each color. So i dose daily 26 ml of calcium a day. My math, rounding numbers for easy, comes to .5 ml a day of each color and i want to dose weekly so 3.5 ml once a week. I was gonna do 3 ml just to be on the safe side to not OD the tank.

Can some one just double check that i did that right lol.

I am not sure which 2 part you use, however, it is simply 1ml of each trace per every 20ppm of calcium used.

Im using brs 2 part pharma cal and alk.

Oh ok so whatever 20ppm of calcium is in ml (via their calculator) would mean 1ml of trace. The only trace element you would be missing is strontium and barium

FYI, strontium is not a trace element. It is a major ion.

Barium is usually considered a minor ion, not a trace element.

I guess I was refering to more common lingo as major elements being alk, calcium, and mag, with the rest being minor and trace elements. Do you know the function of strontium? I thought I saw it has something to do with rigidity or as a substitution for calcium in skeletons but I am not sure.

Strontium does substitute into all types of calcium carbonate roughly equally, whether it is abiotic precipitation of pumps or a coral skeleton, because strontium looks chemical very like calcium. So it gets in "by mistake". Whether it imparts any utility (or undesirability) in a skeleton is not at all clear.

I discuss strontium and what is known to actually need it here:

This article on strontium is the second of several that delve into a variety of issues involving magnesium and strontium.
