Reef Chemistry Puzzle #8

[Raul-7]

Second guess, CO2. Used by all photosynthetic organisms.

@jda @MnFish1

Any guesses? :)

Ammonia. However. -hmmmm

 

[MnFish1]

TDS meter works on principle of measuring conductivity, so it cannot be any "mineral".
I suspect it's something in gas or liquid form.
Ammonia in typical Reef Tank is mostly in liquid form, but in neutral pH it would be ionized ammonium kation and it would be detected by TDS meter.
Bacteria and corals consume ammonia, so this is my guess.

I don't think you're correct - Sodium is a mineral

I feel like it’s C02 but I don’t understand the freshwater ph7 part. CO2 lowers ph…

 

[TokenReefer]

A seahorse! Easy... Had some help tho tbh

I don't think you're correct - Sodium is a mineral

And that, precisely it cannot be Sodium as TDS meter would've detect it.

 

[MantisShrimpMan]

I’d guess CO2 as well. Aside from that, maybe alkalinity?

Not sure what you mean. I said it wasn't sodium

Silicate

 

[Miami Reef]

Good guesses so far!

I haven’t seen the answer I was looking for yet. :)

Answer coming later today.

Answer coming later today.

Awnser!??!
I have no clue.

HI! I asked Randy if I can do today’s Reef Chemistry Puzzle. He generously said yes!

Reef Chemistry Puzzle #8

Two clues today...

1. Loads of things want to consume me in a reef tank.

2. I’m pretty shy. Not even a TDS meter can detect me…but it can if you put me in freshwater at a pH of 7.

What am I?

Good luck! ;)

A marine shrimp!

Lots of things want to consume it
Is definitely shy.
Not detected by a TDS meter in a saltwater tank.
Is detected in freshwater at pH 7 (so long as you wait for it to die and decompose)

Easy!

Yup, has to be this or CO2.
I wonder if this seahorse has a University degree in chemistry?

So thanks for the puzzle. Can't wait for the answer.

I'm going to say - mixing human emotions to a chemical/element/compound might not be totally fair:).

Magnesium

 

[Raul-7]

I had a feeling it was an organism...


But wait, this a chemistry forum! :confused-face:

Hmm, Calcium Carbonate?

 

[MnFish1]

Yup, has to be this or CO2.

So thanks for the puzzle. Can't wait for the answer.

BTW - I don't think you're right - but - the answer was funny
