Is there a significant difference between the 2. I need over a gallon for my new FX5 I'm picking up and I was wondering if it would be better to use the pond or the regular? Anyone have any experience with the two?

Or is it better to use the more expensive FLuval Biomax?

or you could be like me, have a sump and use matrix, rings and bio balls because youre an idiot and didnt plan ahead. at least I'm covered for different scenarios I guess
