Thank you Matt!
Thank you Matt!
Just wanted to post a copy of a thread on my new Tunze 9020 Skimmer I got through this groupbuy and say how great it was for Matt and Natural Life Aquarium in Sunnvale to do this!
Tunze 9020 DOC Skimmer report
Hi everyone!
I have had my 9020 skimmer up and running for a week now and wanted to report to everyone since this is a new to the market.
Fist of all this is a link to the tunze site with specs/info:

The 9020 is actually dual reactors mounted in 2 of the tunze comline boxes side by side. This picture shows it from the back with the included skimate drain hoses

This picture shows a front view with the "standpipes" inserted for in-sump use

Note the (metric equivalent) of a 5 gallon bucket. This is how Tunze ships the unit and they suggest using it as a skimate collector--if you can imagine 5 gallons of skimate!
I actually bought this unit because Tunze has an alternate "plankton friendly" configuaration for in-tank use (although I still keep mine in the sump).
It basically involves removing and plugging the standpipe holes and each reactor has a sliding intake gate that regulates water circulation with sump or tank water. You can choose anywhere between 5%-70% water exchange with the lower the number the less likely to skim out plankton. The drawbacks are a lower efficiency in "agressive skimming" and you must maintain a fairly consistent water level at the top of the comlinebox (I just raised my sump water level) When using the standpipes (in-sump/not able to run plankton-friendly mode) the water level can vary between about 4-11 inches.
Here is a top-down view of skimmer operating in my rubbermaid sump--note that I switched out the Tunze 90 degree fittings for drain hoses with 45s to clear my not-perpendicular sump wall.

Although I never used a skimmer before because I was strictly using ATS filtration I will say that this skimmer really rocks! I am averaging 350ml of skimate every 1-2 days in plankton-safe mode. Run the other way I am sure it would be even greater (so maybe the 5 gallon bucket is not overkill!
Here is a dark picture showing a measuring cup of skimate above and to the right of skimmer.

And here are views of my display tank on the other side of the garage wall from my sump.

I would like to give a big thanks to Roger at Tunze for helping me with this purchase and an even bigger thanks to Matt Hopper aka Al G. Blenny for setting up a Tunze group-buy that made it economically feasible to buy this skimmer.
Thanks guys!
