IceCap Reef Sump 30, 36, 36XL, 48XL Replacement Lid 3
Maintaining clean, uncontaminated freshwater in an automated top-off reservoir is vital for preserving exact salinity levels across large marine and reef aquariums. The IceCap Reef Sump 30, 36, 36XL, 48XL Lid 3 (SKU: IP-RS30-L3) is the official OEM replacement acrylic cover plate engineered specifically for the dedicated freshwater ATO reservoir across the IceCap Reef Sump 30, 36, 36XL, and 48XL series.
The IceCap mid-to-large reef sump lineup integrates a dedicated freshwater reservoir compartment right into the sump chassis to automate daily evaporation replenishment. Because these sump sizes share a standardized reservoir top opening, Lid 3 provides a universal fit across all four platforms. Without a properly fitted cover, this pure RO/DI water chamber remains vulnerable to airborne dust, salt spray from turbulent drains, and ambient lighting that promotes nuisance algae buildup inside the reservoir. Lid 3 drops flush over the top rim of the freshwater section, sealing out external debris, slowing evaporation of pure RO/DI water, and maintaining pristine water purity for your dosing and top-off gear. Over time, original acrylic lids can become scratched, chipped, or misplaced during system maintenance. Replacing a damaged cover with an authentic IP-RS30-L3 restores proper enclosure aesthetics and protective performance.
Ideal Replacement Scenario
If your original Lid 3 has cracked, warped from close proximity to high-output lighting, or was misplaced during routine tank maintenance, installing the authentic IP-RS30-L3 restores secure cover protection for your freshwater auto top-off supply.

Installation & Replacement Guidelines:
Lift and remove any broken or old lid fragments from the freshwater chamber rim.
Wipe down the upper rim and recessed seating ledge of the chamber to remove dried salt crust and moisture.
Rinse the new IP-RS30-L3 acrylic lid with fresh RO/DI water and dry with a soft microfiber cloth.
Route your auto top-off pump power cable and water feed tubing through the factory clearance notch.
Lower the lid flat onto the recessed lip of the freshwater reservoir chamber, verifying it sits level without binding or pinching cords.
Pro Tips:
- Wipe Down the Divider Before Refilling. When adding fresh RO/DI water to the top-off reservoir, wipe down the adjacent divider wall and rim first. This prevents dried salt creep or stray minerals from falling into the freshwater reservoir and altering your display tank's salinity.
- Maintain Distance from Refugium Lighting. Because Lid 3 is positioned near the center of the sump body on larger configurations, ensure that high-intensity refugium grow lights are mounted at least 6 to 8 inches above the sump rim. Placing heat-producing LED lamps directly on acrylic lids can cause heat warping over time.
