Thanks for the suggestion. I think you've hit the nail on the head as I could actually hear water trickling through it when I tried to set it up initially. I'll try it out again this weekend.

You inspired me to build the reactor in the first place and now you say I don't need it? I think it would be better to have one, especially as I will shortly be replacing my yeast CO2 with compressed CO2 and plan to use higher bubble rates than I'm getting from the yeast.

I've got a couple of spare powerheads lying around, so if the priming doesn't work and I can't find any other solution, I may give a powerhead a go at driving it.
