Hello, what the easiest way to make my small hydor powerhead shrimp safe in my nano?
thanks

sponge filter fit onto the intake works crazy good. and in a nano, it would be plenty of filtration for the whole tank!

almost at the bottom of the page it shows a pic of powerhead with the intake connected to the lift tube of a sponge filter.
