I was wanting to get some of your opinions on filtration options for my 75gal. I've decided not to go reef with this tank, and stay FOWLR. So far I have been running my Emperor 400 & 280 with no problems, but am wanting to get away from them and go with something a bit more hidden. There are so many options out there now that I am completely confused about what to do. My tank is not drilled, so if I went with anything I would have to use an overflow box. I also dont have the money to invest in a nice acrylic refugium or sump. I do have a few spare 10gal aquariums to make one with, but have no clue how. Should I spend the money and get a good canister filter or try to make a fuge out of a spare tank? Also, would a 10gal be big enough for a fuge? What is your favorite canister filters? Thanks for any info I can get, still trying to learn all I can!
