Will adding maybe an inch or two of osmocote plus to an established tank cause problems for the inhabitants..like an ammonia spike?
excuzzzeme;54051 said:Osmocote Plus should never be used in a tank containing Inverts as the amount of Cu is .05% which is a toxic level for some fish and most inverts. For inverts it should not exceed .01%

Which one I would get?
Osmocote Plus 15-8-11
Osmocote Plus 15-9-12
The Osmocote Plus I use is 15-9-12, though the difference is not significant.
