Opinions on Tunze DOC 9010 Skimmer

[Timbo1519]

Hi everyone - I am looking for a new skimmer for my sump. I have a 125g FOWLR tank and need a new skimmer. I currently run a Coralife Superskimmer 125 and really hate it.
I need something that will fit in the sump. My space is 8" x 13.5".
The Tunze really looks like a nice fit for the space and size tank.

Any opinions or other advice would be greatly appreciated.

Never used it but I'm interested in how well it works. I may buy this to replace my AquaC EV-120.

I use a Nano 9002 on a total of 70 g tank and fuge/sump. Grabs what I need. Remember, 9002 is small!!!!

That's good considering it's rated for tanks up to 52 gallons.

Ya, learned lessons. Sometimes just because a device is in mainstream use does not mean it is fantastic. Did research on Tunze and found many high end aquarist use this companies devices. I am sold on the Tunze line.

They work, but for the $$ there are better skimmers out there. some people really have trouble dialing them in, others work perfect out of the box. A good friend of mine had a difficult time getting it to perform when nutrient levels were lower...not that there wasnt anything to take it, but it struggled.


For a small footprint look at the ATI BM160 and the new MSX/Octo line....both utilize a sicce meshwheel and will inject more air for it's size than anything else currently available.

Are external skimmers an option? I used a DAS EX-1 on my old 125 reef and would highly suggest looking into them if you're not limited by it's dimensions. If you can afford it an EX-2, would be even better.

The new Tunze Master DOC Protein Skimmers beat out every other manufacturer for air/water intake. The Tunze 9460 ($1,818 ) has 634 GPH air capacity with 1,030 GPH throughput and uses 69 watts (rated for up to 1,585 gallons)! The Bubble King 300 Internal ($2,069) has an air capacity of 528 GPH with 1,585 GPH throughput and uses 58 watts (rated for 700 gallons). ATI Bubble Master 250 ($840) has an air capacity of 528 GPH and uses 80 watts (rated for 500 gallons).

And what pump do those tunze models use?

the sicce psk2500 ...i left those out as I dont believe they are in his price range. (FWIW, you may want to check those numbers you posted against real user #'s ) rumor also has it the ati controlable sicce's will have a 1:1 air/water ratio

the highest air/intake/watt will likely be by the RD2 with hastelloy mesh...but I dont foresee too many people purchasing that unit

The ATI is 528 GPH.

* Using modified EHEIM / ATI-pumps, it is possible to achieve the exceptional air intake of 2000l/h.
* Small footprint and a low clearing height of the skimmer. This will allow the skimmer to fit into the sump without taking too much space
* Silent operation of the skimmer attributed by the pump as well as the employment of air-filters.
* Ease of maintenance, especially the collection cup which can be easily remove with just one hand
* Competitive price when compared to other commercial skimmers with the same specifications.

For every 3 parts of water each pump pulls in 2 parts air for an efficiency rating of approximately 67%. Most other skimmers on the market have an efficiency of less than 35%. Power Consumption: less than 40 Watts/0.6 Amps per pump. Warranty: 1 year. Recommended Tank Size: 500+ gallons.

Where did you get your stats?

[glassbox-design]

I do not believe that info is not complete. The eheim was used on their "twister" model. They use a modified sicce psk2500 on the bubble master...fwiw, most air intakes are measure in lph/scfh.

The sicces with a meshwheel pull ~40-50 scfh. Dual sicces at 50 scfh (msx 250 or ati 250, is more air than 9460 at lower wattage due to increase in air)

A proper designed meshwheel will pull more air than a proper designed NW. (ati v tunze)
