cobalt

[odjbo]

Hello,

I am trying to prepare my own fertilizers, and have discovered a 'Chelated Trace Mix' commercially available, but it contains cobalt.

Not being familiat with Cobalt, any reasons why this would not be good in aquaria would be warmly welcomed.

Kind Regards,

David, England.

No reason as long as there's not much, like most trace metal co factors.
