Why does brine shrimp contain aluminum?

[Miami Reef]

I read an Aluminum article by Randy, and had a question about this:

Clearly, if aluminum is of primary concern, brine shrimp (highlighted in red) should probably not be on the menu.

If you fed 5 grams of it to a 100 gallon tank every day, that would amount to 5 g x 120 mg/kg = 0.6 mg/day or 219 mg/year. Added to that 100 gallons (379 L), that gives an addition of 219 mg/378 L/y = 0.6 ppm per year. The other listed foods would, of course, contribute much less. Unfortunately, these sorts of raw measures of aluminum say nothing about what form it is in. For example, it might be present as soluble aluminum, or as insoluble (particulate) forms.

Food	Calories/gram	Total Aluminum (ppm)	Aluminum (mg/kcalorie)
Formula One	0.8	15	19
Formula Two	0.8	15	19
Prime Reef	0.8	11	14
Lancefish	0.9	9.8	11
Brine Shrimp	0.3	120	400
Plankton	0.7	8.1	12
Gold Flakes	4.2	80	19
Tahitian Blend	2.4	14	6
Saltwater Staple	3.6	95	26
Nori	3.6	83	23
Golden Pearls	3.9	49	13

Why would Brine Shrimp contain so much aluminum?

Why would Brine Shrimp contain so much aluminum?

Probably as a result of bioaccumulation

I do not know the reason.

know TCIP well as a scientist.
The problem with TCIP is that Aluminum Oxide or Bauxite will be reported as Aluminium, in this form it does not present a problem it is abundant in the environment. The reason is people who are not degree chemists are running amok with this equipment, and when computer says , computer must be right!
Marine pure for example has an amount of bauxite in its composition, and this can cause this false reading, along with other common items such as pump wear rotors and some substrates.
Just about any metal oxides can be falsely detected as metal ions in TCIP, because the sample is turned to plasma

Just an fyi, I believe there is plenty of soluble aluminum in seawater, and some can be released from aluminum oxide.

Hold your horses there, buddy. You are spamming a lot of threads within the past 10 minutes. Being rude to Randy or anybody in this forum is unacceptable.

You are Randy's mother, aren't you?

Request denied. I've provided both my background and science data showing you are wrong in your other threads.
