Do you get air built-up in external CO2 reactor ?

[PeterGwee]

You shouldn't get much if the system is setup properly. Are you having problems with the CO2 level or just bug by the level of air buildup in the reactor?

Recently I noticed air buildup quite fast in my internal reactor - 3/4 filled with air in 2 weeks !

Is the reactor powered by the filter or a powerhead? If it's the filter, the flowrate might have drop quite a bit due to clogging of the filter mediums. You need to clean it.. Personally, I would rather run my CO2 reactors with individual powerheads as they don't clog like filters and flowrate remain quite constant which is important for good mixing.

juggler,

I got 2 of those. Horrible I should say. It doesn't work and it leaked.

Sleepy_lancs, where did you get those reactors? DIY? They should work well imo/ime and should not leak if they are properly sealed.

diy myself. when I finally got it to work.. the rate isn't good enough. Basically the water never gets filled up in reactor.

flow rate not good enough?
or co2 does not get dissolved well enough?
get a bigger diameter tube?
