Tunze Comline DOC Skimmer 9004: Clean Water Without the Fuss

If you’ve ever battled mysterious algae blooms or wondered why your reef doesn’t quite "sparkle," the Tunze Comline DOC Skimmer 9004 might just be the unsung hero you’ve been missing. Designed for saltwater tanks up to 66 gallons, this skimmer packs serious filtration power into a sleek, compact body—no complicated setup, no noise tantrums.

What Makes the Tunze Comline DOC Skimmer 9004 a Favorite Among Reef Keepers?

It Skims Smart, Not Hard

Tunze’s signature Flash Skimming Principle pulls surface gunk fast, using microbubbles so small they could pass for soda fizz—except they’re trapping proteins instead of tickling your nose.

  • Microbubbles measure between 0.1 and 0.3 mm

  • Effective surface suction to catch organics early

Engineered for Peace and Quiet

Let’s face it, nothing ruins the Zen of your reef tank like a buzzing pump. Thankfully, this model runs quietly enough to live in a bedroom tank without disturbing your sleep—or your fish’s.

  • Built-in self-cleaning impeller

  • Whisper-silent operation—seriously, it hums less than your fridge

Smart Design That Just Works

Not everyone has space for a bulky skimmer—and that’s where the 9004 shines. With a small footprint and included magnetic holder, installation is as easy as click-and-stick.

  • Fits glass up to ½ inch thick (12 mm)

  • Designed for rear chambers or compact sumps

Dial In  on Your Skimming—Without Guesswork Involved

Some reef tanks need more aggressive skimming, others less. Tunze makes it simple with a tiered system based on what’s in your tank.

Tank Type Adjusted Volume Recommendation
Leather corals / anemones Use full rating
Mixed reef Reduce by 40%
SPS corals (low fish) Reduce by 60%
SPS + heavy bioload Reduce by 70%
Plankton-rich tanks Reduce by 70%

Why Reef Hobbyists stick with it

  • Reduces algae growth by pulling out nutrients before they fuel the problem

  • Improves water clarity—say goodbye to yellow tint

  • Protects coral health in even the most sensitive reef setups

  • Set-it-and-forget-it reliability for hands-off maintenance
