One important thing is to check the glass on the tank first.
If it is a Hagen Tank the bottom is going to be tempered and can not be drilled. So you have to drill the back.
Also being a freshwater tank for so long you have to be careful because if you have use copper based medical treatments in the past the residue could be toxic to your corals.

I am using that skimmer and I have a 10g tank right below it... just in case it over flows... again.
