X-FLO Protein Skimmers – By RK2
Professional grade protein skimmers for the home aquarium
The most important things to consider when purchasing a protein skimmer are performance, reliability, and durability. The XFLO aquarium protein skimmer combines all the above to deliver one of the most innovative protein skimmers available today!
Don’t be fooled by sleek looks, gimmicky twists, or exaggerated needlewheel performance!
If a protein skimmer looks good and doesn’t perform, how good is it?
RK2 set the bar for protein skimmers in the public aquarium and aquaculture industries and has been the industry standard for over 25 years. Now you too can use what the professionals use! Let’s take a look at what makes the XFLO aquarium protein skimmer stand out from the ever varying protein skimmer designs in today’s market.
6” Diameter Reaction Chamber – allows for proper flow rates and contact times
Counter current flow – allows maximum soluble organic removal
High Mounted Water Inlet – Stable water level control without the need for weirs – NO FLUCTUATING FOAM LEVELS!
Baffle Plates – stabilise the foam head and direct foam towards to the collection cup
Pump Not Inside Skimmer – maximum volume for contact time
XFLO’s Domed Lid – allows foam to roll away from riser tube and into the collection cup
Cleaning the XFLO – Quick, simple, and does not require tools.
Flexible Installation – can be installed in or out of the sump
Choose Your Own Pump – Pick your preferred brand .
Collection Cups – Sealed with a simple o-ring that allows for easy removal

Demand a Higher Standard: XFLO Skimmers by RK2
From materials, to research and testing, RK2’s XFLO skimmer was developed and designed with a higher standard in mind.
XFLO is made from the highest quality materials available. Our moulded bases are made from High Density Polyethylene
(HDPE) that doesn’t require gluing or bonding to fabricate. The reaction chamber is made from a single section of acrylic tube. The riser cone, collection cup, and collection cup lid are made from nearly non-breakable polycarbonate material and our Mazzei Air Injector (Venturi model only) is made from highly durable ozone resistant Kynar. This guarantees it will not break down when exposed to ozone.
XFLO has been tested and designed to run at specific levels of air injection. Don’t believe that the more air/bubbles you inject the better the skimmer will perform. The concept of increasing air flow while increasing contact time is scientifically impossible. Too much air, and the reaction chamber only fills with foam, which displaces water and decreases bubble contact time with “dirty” water, along with the true tank turnover rate.
RK2 Systems, Inc., the parent company of XFLO, has been the industry standard for over 25 years in the public aquarium/zoo sectors. We’ve taken their knowledge and applied it to making a protein skimmer designed for the home aquarium.
Made in the USA!
XFLO Skimmers are designed and manufactured in the USA with the highest-quality materials in the industry.
RK2 AC Series Foam Fractionators
Meet the newest models of RK2’s commercial foam fractionator lineup! Our AC series is designed for low flow rate applications while keeping the performance and quality that larger RK2 models have become known for. RK2’s nearly 30 years of engineering experience combined with the extensive R&D we are proud to offer a truly commercial grade foam fractionator for aquarium professionals, home hobbyists and aquaculture professionals alike. These units are built to withstand the most demanding applications. We utilize a design that is based on proven science and volume metrics to bring you the best performing fractionators available today.
All RK2 fractionators utilize counter current design. This means incoming (dirty) water enters high on the reaction chamber or vessel. The incoming water then travels downward through the rising air, which is injected low inside the reaction chamber, before exiting the bottom of the reaction chamber. In comparison, a co-current designed model has it’s incoming water and air/water mixture entering at the same level inside the foam fractionator. Once inside the fractionator, both the incoming water and air/water mixture travel in the same direction, which offers little to no mixing and operates with a much shorter contact/dwell time.
The AC series is made from the highest quality materials available. Our molded bases are made from High Density Polyethylene (HDPE) that doesn’t require gluing or bonding to fabricate. The reaction chamber is made from a single section of acrylic tube. The riser cone, collection cup, and collection cup lid are made from nearly non-breakable polycarbonate material and our Mazzei Air Injector (Venturi model only) is made from highly durable ozone resistant Kynar. This guarantees it will not break down when exposed to ozone.
When coupled with the recommended L1/L2 Vectra pumps, our foam fractionators operate at approximately 1amp of power at 12VAC. Simply put, there is no reason to look anywhere else for your foam fractionator needs! Whether you are a hobbyist in need of a fractionator for your larger display tanks or an industry professional in the aquaculture or public exhibit sectors, the AC series fractionator by RK2 is your answer!
