I think this is a good experiment. I was always told that Purigen didn't work in saltwater tanks for some reason. I'd like to see some real evidence and reasoning as to why though.
As a side question Randy, if a system has no problem keeping NO3 & PO4 at very low levels is there any real reason to attempt to remove DOC using GAC, purigen or skimming?It will bind organics very well in seawater, and that's the only reason to use it. You can remove organics, either as the end goal, or to prevent them from breaking down into inorganic nutrients.
What it won't do (I believe) is bind any significant amount of nitrate, nitrite, ammonia, or phosphate directly from seawater at the concentrations normal for reefs.

They could test it against their ROX...Seems BRS don't sell Purigen so I guess they won't be testing it any time soon

Yeah, that makes sense.although BRS are very fair & honest, I'm sure, some people may suggest the test null & void sighting conflict of interest.
I was suprised to discover that BRS doesn't sell Purigen.
Brs is big on testing products before selling them. I guess this hasnt made it through testing yet. At least enough to be in their store.Yeah, that makes sense.
I wonder why they don't.
Maybe there are other reasons they don't sell it? & if you don't sell it why test it.Brs is big on testing products before selling them. I guess this hasnt made it through testing yet. At least enough to be in their store.
