What's in that skim mate?

Really good analysis;

Pulled up an old gem there. Good stuff.

I thought it was fascinating what skimmers actually pull out of the water. Not as efficient as I always thought.

I wonder what the results would be on a different system. I mean, could there be any reason at all it might pull out more dissolved organic compounds on one system, than another?
I find this hard to believe, since the amount of skimmate pulled from my system is quite massive, and yet, I don't believe I add that much to the tank with just water changes and alk dosing.

It was interesting that a high percentage of the material was inorganic. Calcium and Mg being part of the total. It's only getting 30-35% of the dissolved organic carbon.

Funny they didn't address efficiency. Good point, I wonder if other skimmers are more effective on DOCs.

They addressed that it would be different between types of systems.

Should bottle up out skim and send it their way.

I suspect the chemical analysis would cost significant $$.

I have considered shipping water out and getting a mass spectrograph of it. It would be nice to have a lab calibrate where I really am.

Just wondering why you are interested in mass spec analysis on your water? At work we get water isotope analysis done for about $150, this is in Canada! Water analysis can have a very wide range of price based on what you want to look at!

To know exactly what is going on in your tank. There is a ton of stuff going on in our water that even on a hobby grade we don't understand...and probably some on a higher level that we don't.
Consider those that claim some of the necessity of vitamin C and other such things for keeping coral... how is anyone to know for sure? Won't until someone dives into it.

I hadn't read the the article before I commented what you are looking for is a elemental analyzer. It vaporizes the sample blasting apart the compounds. Very cool machine! Most universities have at least one of these, they can do many runs a day so are sometimes pretty cheap analysis!
