IME Before I got my seaclone 100, I didn't think it would work (because of others' biases as well as my own). But after having tried it myself, I have had luck with it. Then again I have it on a 10gal. What size tank are you putting it on? How will you be stocking the tank? Granted the Seaclone 100 is probably not the best, but it works for me.\
