Where is aluminum coming from?

[purpfish]

My last two icps have shown high aluminum (83.8 ug/land 89.1 ug/l on ICP-Ms) where could it be coming from? return Pump is a mighty jet but my Wavemaker is jebao so I thought I might be coming from that but I honestly have no idea,

Any white media in use?

It may not be high enough to cause apparent issues.

Yes but White media (seachem matrix) was removed last icp

What was the Al value in the last ICP and how long ago was that?

83.8 and 89.1 one month after

I'd keep watching, but there may be other sources as well. Salt mix and additives are much more likely than things like pumps.

Could it also have been from stirring the white media up when I removed it?

Yes, definitely.

Seachem matrix is pumice stone, not ceramic media like Marine Pure.

Does that make a difference @Randy Holmes-Farley?

Any thing ceramic will definatly give you aluminum. I had the balls in my tank and removed them and went down. Have you done any waternchanges since removal?

Pumice can contain substantial aluminum.
