Anybody have any experience with the large CPR hang-on refugium? Would it work well with a 75 gallon reef tank with 80lbs live rock? In addition, how many fish are too many for a 75 gallon?
I would recommend the biggest fuge that you can fit in your setup. A 6 gal fuge is on the small side, but if that's all the space you've got, it is better than none.
i use one on my 100 gallon, it works well but i always think it is too small. i dont have room for a big refuge so i think it is better then nothing. i put chaeto in mine and some sand and rock.
