so i found a "100" the measurements make it a 125) gallon fish tank less then a half hour away from me for $75! it comes with a saltwater light which i wouldnt need because ima freshwater guy, however its just the tank... would it be better if i spent $200 for one that had filters and the full setup? any help appreciated as this is my first attempt at getting a"big" fish tank, largest ive had was a 30 gal acylic that unfortunatly broke on my years ago
