I love my tunze 9002 aswell, it can be set very easily to only remove the nastyest brown gunk... its silent, no micro bubbles and been running about 4 months now and no problems

How large is your tank and what kind of bioload?

33 gallon right now, with 20 gal sump. I have a small bio load though, softies, goby, pistol shrimp, snails and hermits.. but the skimmer still removes nasty brown stuff.. thick and gross

Hey Oscar, if you were thinking on getting the Aquamedic Turbo-flotor, Red Coral in Calgary carries them (a Canreef sponsor). Not sure I'm a big fan of the original Turbo-flotor but I'm sure there are people on here that you can ask since it's been around forever.

One last try with this skimmer. I turned it 180 degrees so that instead of emptying into chamber 3 it empties into chamber 1. This is an AIO tank with overflows in chambers 1 and 3 and the return pump in chamber 4.

Now the water exiting the skimmer has twice as far to travel before endng up back in the display. We will see how this works since now 1/2 of the water it is skimming is previously skimmed.

This would be a similar effect to some of the nano skimmers which appear to have their intakes and exits either in the same chamber or right beside each other.

This skimmer has always produced a reasonable quantity of skimate it has just been madening with the micro bubbles.
