well i am not new to fish keeping but i need a lil advice on filtration for my new set up. i am buying a 37 gallon tall i know its an odd size but hey in my new apt its all i have room for. i was talkin to the owner of the LFS and he suggested a HOB and an undergravel filter for my new tank. he knows i like to overstock and i always have been one to go a lil on the excessive side for filtration but i have never used an undergravel filter b4. i was doin a lil pre shoppin and noticed at bigalsonline the rena filstar canister filters i was very impressed with what i saw . so if anyone would care to chip in thier two cents on UG filter and HOB or cannister and HOB i would greatly appreciate it.
