Hi all. I have a 55 gal. long planted tank and a co2 system and a Cascade 1000 canister filtration system. I am currently using the little in tank ceramic defuser, but I am not satisfied with the difusion of the co2. I am planning on going with an inline reactor to be attached to the outtake hose. There is the Sera Flore Active co2 Reactor that comes in size 500 and 1000. Which one will fit the hose of the 1000 cascade canister filter hose? Is there a better inline reactor than the one I am looking at?

I guess the problem I am having is I don't know what size the hose to the 1000 canister system is. Any help would be appreciated.
