Just starting my planted tank and am trying to decide on which co2 diffuser to use. I have a 55 gallon tank with a fluval 305 filter that I will soon be upgrading to something a little more powerful. I have a hydor inline heater connected to my filter. I am trying to decide if I should get a inline co2 diffuser and connect to my filter or get a bazooka type in tank diffuser? which ever way I go I am going to get two so I always have one to swap out during cleaning.
