Aquarium Advice Regular
Just make sure when it`s running that it leaves you enough room for the back flow if the power goes off. Or dreill a small hole in the return line at the top. I dont have hole drilled in mine but my refuge handles the backflow.
The only thing I see has already been covered. I like the media shelve you put in.
I have a 55 gallon that I turned into a sump.
