Oxydator

[JohnA26]

In a nano, 13.5 gallon? InWhere is the best placement of an oxydator? Should it go in the return area where activated carbon is? And shouldn’t it be just 4% hydrogen peroxide?
Or is it not recommended for a mixed reef tank?

Anywhere it can fit, the placement will not matter. That small of a tank it won’t matter

i know folks using 12% use what you have
