Is Aluminum Dangerous for Shrimp?

2074 3
Random thought. Is aluminum dangerous in a shrimp tank? I have a lot of it in my house and was thinking of maybe using it for my java moss.

I think the smart money would be on avoiding Aluminum.

But I am not where the smart money flows. Given that Aluminum is so reactive we never see the elemental form, I tend to doubt it would cause much problem with pH 7 or above and I would think (maybe read somewhere) that water (maybe soil?) needs to be under pH 6.2 or pH5.7, something like that.

I figure Aluminum is the third most abundant element on earth it can’t be that toxic

My experience in using Alum (KAl(SO4)2*12H2O) as a flocculent is that above pH 7, anyway it hasn’t been a problem.

Maybe time for a mason jars some water a few pieces of aluminum and some Daphnia and see what happens. Would be nice if you told us what happened.
