And composition of marinepure ceramic from their website:

"MarinePure is an inert aluminosilicate ceramic that has been fired over 1000°C. It will not leach into tank or pond water."
Knowledge is power. Now we can hold manufacturers claims to the fire.
A little off topic, if the manufacture's claim about surface area hold true, instead of using their expensive ceramic , why not using a bunch of sponge (the type from $ store for washing dishes).
Then you won't have to worry about Al.
