• ReefCan 18 Auto Top Off Reservoir — 18-liter (4.75 gallon) gravity-fed ATO reservoir with integrated pump and level sensor. Connects directly to your MAX NANO or REEFER sump for hands-free evaporation replacement.
• ReefATO+ Retrofit Kit — Adds automatic top-off functionality to MAX NANO & REEFER models that don't have it built in. Includes optical water level sensor, tubing, and all mounting hardware.
• NanoMat Automatic Roller Filter — Replaces traditional filter socks and sponges with a self-advancing fleece roll. Automatically feeds clean media as the current section clogs, keeping your water crystal clear with zero effort.

• Complete automation package for evaporation top-off and mechanical filtration
• Designed specifically for Red Sea MAX NANO G2 and REEFER G2 systems
• ReefCan 18 holds 4.75 gallons — enough for several days between refills
• NanoMat roller filter eliminates the need for filter sock cleaning
• All components integrate seamlessly with existing Red Sea cabinet and sump design
• Suitable for saltwater reef aquariums

Will this kit work with my original MAX NANO (not G2)?
The ReefATO+ Retrofit Kit is designed for MAX NANO and REEFER models. Check Red Sea's compatibility guide to confirm fitment for earlier generations.

How often do I need to replace the NanoMat roller filter media?
A single roll typically lasts 4–6 weeks depending on tank bioload. Replacement rolls are available separately.

Can I buy these components individually instead of the kit?
Yes, all three items are available separately, but the Pro Kit bundles them at a better value than purchasing each piece on its own.
