Compact & Built to Last

Master crafted from robust PVC and high quality acrylic. All components are marine safe and refined in every aspect to provide the latest enhancements in foam fractionation and the highest in quality.

The elegant “Beer Bottle” curve of the skimmer body naturally stabilizes the air and water mix as they transition upward within the reaction chamber. An impressively compact footprint makes it the ideal candidate for tight sump applications. Every aspect of the skimmer disassembles completely for easy service.

Quiet Performance & Control

At the Core of the K2, you will find the always reliable and Italian made Sicce skimmer pump with a proven track record for being highly durable and packing a ton efficient performance. 

The pipe less output offers fine-tuning and trouble free underwater outflow plus quiet operation. The wedge pipe commonly used on other skimmer to channel outgoing water often causes performance inconsistency and additional sound. Our pipe less design not only saves on space but also allows the outgoing water to exit on the side of the skimmer and below the water surface providing splash-free circulation in the sump.

Located much lower in the reaction chamber, the unique bubble dispersing chamber offers a multi stage diffusion of water, additional contact time for enhanced foam stability.

Helpful Tips


Protein skimmers only work in saltwater. A steady specific gravity of 1.023- 1.025 is recommended.


It is recommended that the sump water level stays stable at all times. The use of dedicated baffles or auto top off unit allows for more stable filtration from the protein skimmer.


Never adjust a skimmer after servicing the aquarium or feeding.

Skimmer pumps are normally louder during the first 2-3 weeks until a bacterial coat lubricates the rotor.

Safety - Never allow the skimmer pump to run dry. - Do not insert/pull the power plug with wet hands. - Only clean the skimmer with vinegar and water. - When servicing the skimmer please remove the plug from the power socket first. - Must be used with intended power source only

  1. high quality skimmer at entry level price. Review by daniel

    This skimmer impressed me from the moment it was unpacked. The first thing I noticed was how well put together it looks and feels. All parts seem sturdy and durable, also very easy to completely dismantle and reassemble for cleaning and maintenance.
    Setting up is very easy. And the overall foot print is somewhat smaller then other protein skimmers of comparable volume rating. At 17x15cm it is certainly the only skimmer in its class that would fit in the small space I have available in my sump. As with most skimmers water level is key. The recommended 8inches deep works well for me.
    Operation is near silent, even with cabinet door open.
    Adjustments are easy to make via the large outlet adjustment knob controlling a paddle shaped gate over outlet. Due to size of the knob and the fine guage bolt it drives adjustments can be very precise.
    Collection cup drain is very neatly plumbed ready for drain hose connection.
    Unit comes fitted with a water level sensor in the collection cup lid that once connected to a control unit will be set up to turn off the skimmer if collection cup nears overflow. Preventing scum overflowing back into your tank. Control unit was not available when I purchased this so I have no.comment on its effectiveness but I do find this a useful feature and look forward to testing it in the future.
    Manufacturers guidelines rate this from 400l lightly stocked down to 280l at heavy stocking. My tank is only lightly stocked and with a total system volume of just under 200l I fall well below the recommended tank size for this skimmer. This has meant that I have to run with the outlet valve dialled to around 80%closed but still works very well. At 1 week in I am getting a good thick dark sludgy skimmate.
    While this is the only skimmer in this size class I have used personally. At close to half the price of some skimmers of a similar volume rating I see the microbe lift skimmer range as an extremely well put together, value for money, product. Perfect for those starting out in the hobby who may be scared off by the price of some other models. (Posted on 17/04/2016)
