Dkeller, I thought perhaps the silica may have come from the KZ sponge power. Thoughts?

Hmm I'm about to put a block of this in a 30g system.. Do you think it would leach slowly over its lifetime, or just when it's first added?

FWIW, I just got a response from someone on another forum who had high aluminum (>0.1 ppm) and he does use Phosguard as well as GAC.
So the use of GAC alone does not necessarily keep aluminum at "normal" seawater levels.

Anything intended to feed sponges might have some silicate in it, since some types of sponges create a silicate-based skeleton. I fed silica to my tank for a while to encourage sponge growth. I am not certain that it helped, though.

But yeah, I agree that it is unclear if it is leaching or not, I am saying though that even if it is leaching, it doesn't seem to cause any issues. Example of an recently set up tank with way too much Marine Pure than the minimum recommended and a tank that's been up and running for a year were both amongst my examples, so I am just saying that either way, it doesn't seem to be a problem. |

I have been running the 8x8x4 blook for a couple years. Tank does well most of the time but I am currious what my triton results will be. I will post results when they get back to me. It does a great job filtering my tank but if it is leaching aluminum then it will be gone from my system.

It is mailed in the US using their own bag.

What about ceramic rocks? Are they made of the same thing?

Randy - how confident are you with triton's test methods? any idea what methodology they are using? How do they avoid the interferences from any of the other elements? Detection limits? What's their precision/accuracy?

I have seen the detection limits, and they have posted them somewhere (I saw a reposted copy). At my suggestion, they are going to rework their data presentation to not suggest the values are more precise than the detection limits allow. Right now, one might misunderstand how low 0.00 ug/l really is, since in some cases it might only mean less than 0.5 ug/L.
The ICP method is fine overall (I've used it myself for various studies), as long as they do recognize the interferences that may exist. The fact that only some samples get unusually high values for things like aluminum, tin, or lead, suggests it is not a systemic problem. They did tell me that really high phosphate will interfere with iodine, but I do not know what all other issues they may have to deal with. It is a method that one can and must run standards to get values for the various elements. i hope and expect they are doing that correctly, but I cannot know for sure.

I don't know. It sounds like a cement, and people have been using cement rocks for a long time, but exactly what is put into them may make a difference. Cement varies a lot, but often is mostly calcium silicate with some aluminum and iron and other stuff.
FWIW, surface area is critcal for the release of poorly soluble components, so the risks are greater in the same material made high surface area as opposed to just a clod.

I have no idea what their ceramic is made of, but I suppose an email to the company can't hurt.

I just received a response from Paul at Cermedia (makers of Marinepure). He gave me permission to post his email:
Thank you for your question. I have been following several threads discussing aluminum and it is all very interesting. Our product does contain Alumina, which is Aluminum tied up with oxygen in ceramic form, not the metallic form of Aluminum, or aluminum ion as measured by the Triton test. Most ceramics will contain some alumina. Our products have been used many years with great success by sophisticated reefers and they have never seen a problem.
