Aluminum in aquariums?????


Larval Mass
Does aluminum have the same effect as copper on octopuses? The reason I'm asking is because I have a cooler I found for my tank that has an aluminum coil set-up. Can some one give me some advise? Will this work? Thanks !!!!

Aluminium is toxic to marines, it will soon corrode in saltwater. I would advise against using it. Aluminium could also cause problems with low pH if I recall correctly.

aluminium breaks down slightly in saltwater, even though it doesn't rust, in a small environment like a tank it becomes deadly for inverts...thats why they usually coat any alum parts in working pumps, etc. It doesn't effect vertebrates that much, so often a dealer will sell a standard chiller to an invert keeper innocently. That is why it pays to shop at a local store where they keep reef tanks, and know what they are doing...

I know this thread is 5 years old, but I've found myself in a similar situation. Does anyone know what coatings can be used on aluminum to render is safe for a marine aquarium?
