So I am setting up a heavily stocked 30g nano with 10g sump, and I would like to try going all Tunze for flow and filtration (I already have 1073.020 return and a 6015). I was thinking I would wait until the pinwheel skimmer models come out. I read Tunze reps at last MACNA were not only talking up this 9004 model, but another replacement for the 9002 that will have pinwheel impeller, keeping the 9002 dimensions (9001?).
I suspect I'll go with the 9004 upon its release, but I was wondering if the 9001 model still planned as well? Also do you know what airflow numbers and pricing to expect for these new needlewheel skimmers? Thanks.
