Visualize what 1 ppm means

[Randy Holmes-Farley]

Here’s an article about a way to visualize what 1 ppm or 100 ppm or 100,000 ppm means.

Helps one to realize 1 ppm is hardly anything.

I saw the black bead right away...

not really... Very cool pictorial.

My kid would drop that jar and those little beads and glass shards would be everywhere...

It makes the fact that we can ever detect anything in this hobby at the tenths or hundredths of a PPM level with all the other competing elements in seawater feel like magic.

Interesting.
Green I can see 1 or 2(hard to tell) pink maybe a few.

That’s what I was thinking too! Huge self esteem boost knowing that I had the same thought as a scientist!!

*educator, to be more precise.

Saltwater chemistry could be a topic at this conference.

But, but, but what about chasing all those numbers?

Teasing of course - thanks for sharing and hope your day is going well.

Why I scratch my head when 1 ppm is noticed in RODI and alarms go off to quickly change filters. Especially without knowing what that 1 ppm represents.

I still think 1ppm is important. There are some things that you wouldn’t want 1ppm of.

Like copper or phosphates.

Yet placed in perspective, that 1 ppm copper on top off or replacement likely not going to impact overall system. Copper does exist in NSW and so does phospate yet I doubt most systems have 1 ppm copper existing as 100% off that filter no longer being 100%. Plus that 1 ppm could be further filtered through copper and phosphate removing compounds if that's really a concern and should last longer than having to go change out main RODI components at the first sign of that 1 ppm.

I sometimes wonder if RODI sellers promote this fear mongering to get users to spend sooner than was realistically expected.

And to think our sun that makes all this possible is 1 in one hundred thousand million just in our galaxy

The black bead could be in the center of jar. I could anyone hope to find it?

There's radioactive material that would be dangerous to humans in that amount. 1ppm isn't much, and the dose makes the poison, but some things are nasty.

(Though, worth noting that some people have happy, healthy corals at 1ppm phosphate. It's hardly on the level of, say, ammonia.)

Really, the dose makes the poison. .8 micrograms or 0.00000008 grams of botulinum toxin is fatal by inhalation. Considering the average human weight is 62 kg that's 0.00000012 PPM or .12 PPT.

This just confirms the simulation...

Scientifically known as a “smidge”

There could easily be no pink beads visible, let alone lower concentrations.

This has told me that my eyes suck!

Wow that makes me think phosphate is a really bad guy!
