Canister and inline equipment recommendations?

[malfist]

Hi all,

I'm upgrading my boyfriend's 75g to a 125g and taking his old 75 gallon. I currently have a fully planted 55g with pressurized CO2, although I'm using a ceramic diffuser in the tank to diffuse CO2. I'm also currently using two marineland emperor 400's as filters

I'd like some recommendations on upgrading. I want to replace the emperors with a canister filter, and if possible I'd like to pull my heaters and co2 diffuser out of the tank and run it inline with the canister.

What should I look for? What do you guys use?

I would get two canisters, I prefer eheim, and put an inline heater on one and an inline diffuser or reactor for the co2 on the other one.
