Roger,
Just found the info on the Master DOC Skimmers!
Looks very promising!
Did you have the reaction chamber dimensions for the 9440 and 9460?
Saw it listed as 480mm x 580mm on the 9440, and 480mm x 700m on the 9460. I am guessing these are footprint sizes.
Can do the mm conversion if you don't have inches available.

Been looking at H&S, but this looks very good!
Do I hear beta tester?

Thanks,

Todd
 
That is the total size with the pump but the skimmers don't really have a base , it is just a round black PVC plate the size of the tube, the pumps and outlets add a few inches to the diameter. Off the top of my head, the big skimmers have a 14" tube diamter. The smaller ones about 8-10".

We don't have beta test models, the products are tested at the company store and by the product developers.
 
I'm really excited about these skimmers. Does Tunze have any pics of these models in action?

I considered getting the 9015 for my 180g. But since I keep a well fed emperor and two tangs, I figured one of the Master DOC models may be a better fit. Not sure though, since I've never seen any of these skimmers in person.
 
I don't have any pics. I did see them, the models as the Interzoo show were hand made without the final tooling and since some of the tolerances are very exacting and they were mainly just to display a concept, they didn't work perfectly.

At the factory they did have perfect working models but they were unattractive for the same reasons of being really hand assembled without the jigs and tooling that will be used in the production version.

They worked well but I really had nothing to compare it to and it is hard to say from a one time observation, you see a cup of skimmate and the foam and that is all you can judge. What I thought was really neat was 3 things:

The energy efficiency, we can get 800l/h of air for 23W when the competetion needs at least 55W to get 600l/h of air.

The concept of self regulation with no adjustment necessary. Through a complicated feed back system changes in surface tension restrict and open the air inlets to control the foam production automatically and prevent a foam over.

Skimming stops when the cup is full and the cup lifts off with no union or coupling or mechanical seal of any type, instead a bath of water forms the "gasket".

The down side is they must go in sump and they have a huge footprint, the smallest ones require a sump that is 19" across. The majority is the large diameter of the tube.
 
When you say 19", you mean width of the sump? Or length? I keep my skimmer in a 40g breeder sump that is 36" by 18". Would a master DOC with 2 pumps fit?
 
The size is basically a diameter, including pumps and stand pipes. It would fit because the pumps can be removed and connected with a pipe or hose instead of directly to the side of the skimmer and this buys a couple inches.
 
Have a g-6 in in a seperate compartment in my sump, it barley fits, looks like the master will be close. Looks like the reaction chamber will be about the same and the pumps a little smaller.

The Comline DOC skimmers will fill that end. These were specifically designed for big tanks.
