Ordered the last copy earlier today. 26 years old though, before ICP was developed I believe. Still, I like these type of books. Thanks for recommending

I am a fan of pelletized carbon such as the one you recommended. Would not buy any other at this point.
Unfortunately, they do not seem to sell to individuals, and their online seller went out of business...

The avast marine tests theirs. Or if you want hardcore this is what I use. https://www.cleanwaterstore.com/activated-carbon/catalytic-activated-carbon-05-cu-ft.html

I believe this is the same product for sale since its the same logo on HDLTD website and same on bag of carbon?

Looks like the same stuff in my RODI cartridge

Could be. Some of the spectrapure cartridges do use CAC and not GAC. This brand was tested for phosphate, ash, and metals. Came back pretty pristine.
Edit - there are a bunch of CAC brands out there. This was one of three I’ve seen tests on.

The carbon rabbit hole!!

If anyone is interested in splitting a CAC order let me know. I want to switch to CAC but don’t use carbon often. Therefore, 13.5 pounds would take me years to go through

The high quality pellets that Polyplab and Fauna sell are better IMO, same higher quality and break less. Potentially the same product that Erin recommended but I cannot confirm.
For those who aren’t aware of the CAC carbon from
ClearwaterSolutions, here is an explanation on why many hardcore SPS folks (specifically, the Moonshiner community) have stopped using ROX carbon and switched to CAC:

Thanks for sharing. I heard that this is a moonshiner thing to use CAC.
I thought there was a difference between DOC and SAC? My SAC was between n.d and 0.4 previously, so not a problem I am trying to fix.
But more surprisingly, Salem recommends in this article three times the amount of CAC vs other higher quality carbon, which does not surprise me that it might be more effective in reducing DOC/SAC
. I am intrigued though if it absorbs less trace elements.
Did you notice any difference when you switched to CAC?Thanks for sharing. I heard that this is a moonshiner thing to use CAC.

I bought the 0.5 cubic feet which will take me years to go through. Maybe I will break it down into smaller chunks and see if any club members want to buy a small amount to test out.

Well can use it in ur RODI system as well same stuff or better thats already in ur carbon canister.
Good idea! I just replaced my carbon filters this past weekend (and ordered a new set from BRS) but will use this 13.5lb pile of carbon I am about to have!

It absorbs fewer traces which is important to me to keep more of the moonshine daily elements available for the corals and potentially fewer corrections ICP to ICP.Thanks for sharing. I heard that this is a moonshiner thing to use CAC.

It will soak up impurities and any potential contaminants better than GAC, and it has been shown to reduce the plastic contamination we often see in our tanks over time. The added benefit is keeping SAC low.

Oceamo ICP-MS for Sac 254?
I do use both catalytic and activated carbon.
Ive read tones of articles regarding Catalytic vs Gac which most stated catalytic was superior for chloramines mainly for drinking water uses which one article was the one moonshiners posted regarding catalytic but not much on trace elements?
Have not found any articles/ lab studies regarding it being more gentle on trace elements nor ICP tests confirming..If Catalytic has been tested and confirmed to remove more elements in drinking water then why would it remove less trace elements in tanks?
I do think Chaeto continuously uses up more trace elements then carbon does when placed head to head unless you put an obscene amount of carbon in. The placement before skimmer or after it in sump or no skimmer ? , quantity which recommendations all vary?, how often one changes out also all varied info from 3 days to 30 days? Coral quantity and their uptake along with macro algae? These play a huge roll in testing traces and may be different from tank to tank in general..if anyone finds scientific tests / articles regarding carbon and trace elements with simple control factors please share maybe Ive been looking in the wrong places rabbit rabbit wabbits!!
