Upgrade your IceCap 10G or 20G All-in-One (AIO) reef tank with the Roller Mat Filter & RollBot—a smart, compact, and hand-crafted mechanical filtration system designed to deliver crystal-clear water with minimal maintenance.
This innovative drop-in roller filter fits perfectly into the rear filtration chamber of both the IceCap 10 and 20-gallon tanks, replacing messy filter floss or sponge blocks with automated mechanical filtration that actively removes waste before it can pollute your water.
Built for both form and function, this roller system transforms your IceCap tank into a high-performance nano reef—perfect for reefers who want a clean aesthetic, ultra-low maintenance, and superior water quality.
Perfect Fit for IceCap Nano Tanks
This roller mat filter is designed to drop into the overflow chamber of the following tanks:
-
✅ IceCap 10G AIO
-
✅ IceCap 20G AIO
Both of these sleek AIO systems are known for their ultra-clear glass, compact footprints, and clean layouts—making them ideal for reefers who want simplicity without sacrificing performance. But like most AIO setups, the stock filtration (floss, sponge, or sock) can quickly clog and must be manually changed, often daily.
This roller filter solves that problem with smart, hands-off automation.
Powered by RollBot – No Sensors, No Problems
At the core of the system is the RollBot, a float-free controller that automatically advances filter paper at user-defined intervals. It eliminates the need for float switches, optical sensors, or calibration—making it more reliable, easier to maintain, and perfect for compact AIO tanks.
RollBot Features:
-
🧠 Time-Based Control – No float switches or water sensors to fail.
-
🔁 Fully Adjustable Daily Roll – Set between 100mm and 2000mm/day (200mm default).

Why Roller Mat Filtration?
Traditionally found in high-end sump systems, roller mats are known for their ability to trap fine particulates and remove waste before it breaks down, reducing nitrate and phosphate buildup. Now, with this compact design, you can bring those same benefits to your IceCap AIO setup:
-
✅ Eliminates detritus and suspended waste
-
✅ Reduces algae-causing nutrients
-
✅ Keeps your water crystal-clear
-
✅ No daily filter floss changes
-
✅ Increases biological filtration efficiency
Unlike filter socks or pads that sit in the water and break down waste after it begins decaying, the roller mat lifts waste out of the water column immediately—stopping the nutrient cycle before it starts.
Prototype Status – Hand-Crafted & Continuously Improving
Each Roller Mat Filter is handmade from laser-cut acrylic and 3D-printed components. This is an actively evolving prototype, and we are constantly refining the design based on real-world testing and user feedback.
🛠️ Because of its handmade nature:
-
Units may show minor cosmetic imperfections from 3D printing or assembly
-
These do not affect function or reliability
-
Each batch may include slight design upgrades
You're not just buying a product—you’re joining a growing community of nano reefers who value innovation and performance.
