I bought a Tunze 9001 for my AIO 55litre aquarium. It fits nice and snug in the first chamber. It's been running for 1 week and produces nothing more than an almost clear wet skim. It's at the right water level etc... The air intake is currently at max meaning maximum air is allowed in to the skimmer. I assume that may be a place to start but how would I go about dialling that in as the bubbles currently go half way up the neck as they should? Another thing is it is quite noisy but it should be rather quiet from what I understand? Thanks.
