No issues. Does not move water like an fx4 or fx6 but holds lots of Bio. You can get two for under 200 bucks which would do the trick. I have a pretty high bio load in my tank....what are you keeping?? I have a Mata mata turtle in my 120 along with two 7" plecos, 5 SDollars, a 10-11" Lenticulata Pike and a huge sydont cat.
I have a lot of different small and medium sized stuff. Mollies sharks tetras, gouramis. Just regular stuff
