C02 and sump

[Joeg123]

So I have a waterbox 110.4 that used to be a reef and I swapped for freshwater and then recently started plants... so I've got co2 up and running currently have the atomizer just below the return pump and the co2 is being sucked in and fed to the main tank.. its working well but still quite a few bubbles are coming out of the return and going to the surface.. I have one of them bazooka atomizers

I feel like a reactor or inline diffuser is more efficent but the tubing I have for my return pump (vectra m2) is 25mm and I cant find a inline difuser that will fit

just wondering as I have the sump could I just get a seperate pump to sit in the main chamber of the sump and hook up a inline diffuser to that and have that leading to the pump chamber? not 100% sure how the inline diffusers work so if it was possible would I need a pump with a minimum flow?

Yep, you can get a separate pump for the inline diffuser and run that to either the display tank or the pump chamber. Or you can plumb in a 'bypass' on your return pump which is just a pair of T fittings and valves so you can control how much flow goes to the diffuser.

Thank you, I have a spare ehime compact 1000 would this be strong enough?

Yes, probably? 🙂 I only use CO2 reactors and with them I never measure flow rate, I simply adjust the flow rate to be as strong as possible but so that no bubbles of CO2 make it into the display and no bubble of CO2 forms at the top of the reactor.
