Thank you Anastasia, that's a better idea, and I like the fact of not having to add anything cumbersome coz the airlocks are incorporated into the tubing

DollyAmbition, there has been a change of plans :-/ I won't be traveling out of the country anymore, however this weekend I'm going on a group trip first camping :s and then in a hotel room with other people who don't know and I won't tell them about brava... so this presents another set of challenges I'm already laughing thinking about how am I going to conceal the domes and the noise once the smartbox goes off in the middle of the night! Lol
