I bought the same skimmer for my 46gal FOWLR
. As soon as I put it together I knew that it would take so much away from my tank (aesthetically) that I couldn't use it. I packed it up carefully and returned it.
There are several skimmers that appear to be much less intrusive on the tank appearance. I'll let someone else make recommendations on this.
I decided to buy a wet/dry and put everything down below. Skimmer, heaters & probes are all out of sight. It also increased my total volume of water by a few gallons. If I had it to do again the only thing I would do differently would be to use a larger wet/dry or a large sump.
