i am setting up a regular 29 gal tank and was wondering what would be good filtration choice. i am wanting to make it a reef tank but i am not sure if this is possible. I was going with a cannister style filter but i am not sure which is good and what flow rate would be sufficeint. for lighting i have 175 watt MH or i ahve a 96 watt PC. Any help would be greatly appreciated.
