I'm about to buy a CO2 system, and it's asking for "hose fitting size" for the reactor (http://www.aquariumplants.com/AquariumPlants_com_s_Own_External_Reactor_p/ext5000.htm). The choices are 1", 1/2", 3/4", and 5/8". Since this is the first time I'm going with a pressurized system, I don't have a clue as to what I should get.
What size should I choose? Why would I pick a larger size over a smaller size or vice versa? This is for a 150 gallon tank, btw.
Thanks.
