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: http://www.tunze.com/149.html?&L=1&...r_tunzeprod_pi1[predid]=-infoxunter028=infoxunter028]Tunze Comline Doc Skimmers

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.

Here is view of the skimate drains into a plastic cereal container.

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

If these pictures don't post please go to my gallery where they are located.

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!
 
Sorry about the links, they only work in the original post in the eqipment forum. You can see the photos by going to my gallery.

Wow - that is a lot of dark skimmate for a couple of days; how big of a tank is it running on?

I think Tunze does have a winner here; I just put the 9015 skimmer in my aquarium to replace a 3130/2, and as promised, it is a much more aggressive skimmer. I plan to experiment with the 3130/2 with a mesh over its inlet to help in raising clownfish fry. It might be able to help keep the water non-toxic without removing too much of the food for the fry.

Hi James,
That is a lot of water to process, but it certainly looks to be doing a good job. I have the 9015 on a 30 gal cube so it isn't having to work so hard!
