Fantastic, thanks Randy! I actually stumbled upon this article yesterday after I received the results and used it to not TOTALLY FREAK out about the .31 ppm aluminum haha...I will give it another detailed read after work!

Here is a photo of the bottom of the pump btw. Looks like a little rust may already be forming on some of the screws (especially top right in the photo). @amsterdam_reefer and others, you guys think this is at least a partial culprit?I think I may have found a different culprit! I was mixing up my next batch of saltwater and when I was done I examined the pump and sure enough it had exposed metal screws on the bottom. Sometimes I would mix the water days in advance and I would just leave the pump in the brute trashcan until I pumped the water to my tank, could this be the cause @Randy Holmes-Farley ?
Ironic that I was about to begin a strict water change regimen to alleviate the problem but I may have just made it worse!
For those curious, it was a hygger brand pump.
Randy,Are leather corals closed up or do you otherwise detect a problem?
If not, I'd just remove the suspected source and continue with your normal water changes.
I’m now in the same elevated Al boat, but believe it was the phosguard leaching. Yes I have the same media but the real correlation for me is due aggressive phosguard I been running to address a phosphate problem.
the particulate vs disssolved is interesting. The former suggesting once can eventually physically remove it over time with WC and vacuuming, but it doesn’t seem to click for some reason. I ran aggressively in a reactor in the sump and eventually will vacuum the hell out of the sump, but water sample was from DT. Does the particulates really dissolve and thus is detectable in the water sample? If so then physical removal may not be the solution. ??
"Particulate" in the case of aluminum does not have the same meaning you might ascribe to it as a big chunk floating around that will somehow be removed before an ICP test. The particulate may be too small to see and will be detected by ICP.
What aluminum levels do you observe?
