Deltec​ i-Series internal skimmers

Deltec has launched a new skimmer series, known as the Deltec i-Series. With many new features, this series of skimmers will outperform most other skimmer brands even more.
What are internal skimmers?
Internal skimmer have the skimmer pump built on the inside of the skimmer unit. This means that the skimmer can be used as a stand-alone, and does not require the purchase or installation of an external pump. 
The Internal skimmer stands within the sump, and needs to be partially submerged to function.

Deltec i-Series

The Deltec i-series has a great set of improvements compared to its predecessor, the SC series. With this new internal skimmer series your aquarium will enjoy the best skimmer performance possible against the highest efficiency.


The benefits of the Deltec i-Series are:

  • Highly efficient cylinder shape

  • Safe by newly developed emergency overflow with water level indicator

  • Whisper quiet through a new hollow chamber floor

  • Extremely low power consumption

  • Quick and easy removal of the pump

  • Variable adjustable pump (with the i-models, not the ix-models)

Manuals for skimmers:
Emergency Overflow

Deltec skimmers are characterized by particularly good skimming results. The Deltec Skimmer i- and ix-Series has a newly developed emergency overflow. This prevents the "overcooking" of the skimmer when the water level in the skimmer rises. This can happen, for example, by discontinuing the conveyor pump and by adding additional water to the filter sump. But even if there are problems with the air supply, e.g. by bending the silicone hose or foreign body in the air intake line, the water level increases. This can cause the skimmer to "boil over" and the water rises so high that it is pressed into the foam pot and the broth is rinsed back into the aquarium. This leads to an extreme load of water. Due to the emergency made by Deltec this is prevented and thus the aquarium protected from impurities.


Emergency overflow pipe & regulator pipe

The water level in the skimmer can be read off at the emergency overflow pipe. In addition, the minimum and maximum markings help to optimize the water level. By the possibility to exchange the emergency overflow pipe with the regulator pipe, the user has the possibility to decide how the pipes are arranged.



The Deltec Skimmer i-Series are operated with the Deltec pump DCC of DCS. This 24V DC pump can be controlled via an eight-stage controller and can be optimally adjusted to the water level and the water load. See below for specific details per skimmer within the i-Series.


The ergonomic cylinder shape

Thanks to the ergonomic cylinder shape, the Deltec Skimmer i-Series achieves the best results with skimming. The shape of the skimmer does not taper upwards. This allows the small air bubbles to rise unhindered, are fully saturated and burst only in the riser of the foam pot. From there, the collected broth can be discharged via a drain hose without having to take the foam pot down.


Hollow Chamber Floor

An additional innovation of the Deltec Skimmer i-Seriers is the hollow chamber floor. This helps to dampen the noise still further, whereby the already quiet Deltec Skimmer i-Seriers is called "whisper quiet". In addition, the water flows back through the hollow chamber floor. The water is fed at the lowest possible point out of the skimmer, as a result of which almost no air bubbles can flow into the aquarium.


Dismantling, Dimensions & Construction

The regular cleaning of the pump is very easy thanks to the simple and fast dismantling of the skimmer. Deltec Skimmer i-Seriers can be mounted and disassembled without tools. Our tests have shown that the pump can be removed from the skimmer in less than 20 seconds.

The dimensions of our skimmers are chosen so that they can be placed comfortably in their filter basin. Due to the high volume of the cylinder shape, a small base area is sufficient. You can operate the Deltec Skimmer i-Series variably in 15cm to 25cm water depth.
