Why am I getting high Aluminum?

CyberGuy · Apr 10, 2020

Hello. I just got back my ICP test from Fauna Marin and found out that I got high Aluminum. My tank is doing well. My tank is a mixed reef. All LPS, SPS, and sold corals are thriving and growing slowly. Sps have great polyp extension.

Oh, also side note: I also have high Sn (tin) level. :-(

Are you using any bricks for nutrient control?

Aluminum can come from a variety of things, especially white (aluminum oxide) media.

Salt mixes and additives may have some. Aluminum parts above the tank corroding can add it.

Don't get too worried if things seem OK. My tests suggested higher levels were necessary to impact the corals I tested.
