The design supports top or bottom water entry via a second dividing plate, and it includes optional precipitation tank and high-grade board to widen filter box capacity. Tank width guidance is specific to 40G breeder dimensions, so users should measure before purchase.
Adjustable Sump Baffle Kit for 10G Tank

This kit tailors filtration for small saltwater systems by creating dedicated chambers for skimmers, media reactors, and refugia in a 10-gallon tank. The adjustable water level ranges from 5 to 8 inches, suitable for various skimmer heights and flow requirements. It is designed for Aqueon 10 gallon glass aquariums with an inside width of roughly 9.85 to 10.2 inches. Accurate tank measurement is recommended before ordering to ensure proper fit and effective filtration.
Aquarium Sump Refugium DIY Kit for Protein Skimmer Sump (10 Gallon)

This 10-gallon DIY kit includes three acrylic dividers to create customizable chambers for skimmers, refugia, and reactors. The board width is 9.92 inches, aligning with many standard 10-gallon tanks. Users should verify their tank’s inner width before ordering. The dividers help establish proper chamber heights to optimize flow and filtration efficiency, accommodating a range of protein skimmer designs and ensuring a stable sump layout.
Aquarium Sump Refugium DIY Kit for Protein Skimmer Sump (20 Gallon Long)

Designed for a 20-gallon long sump, this DIY kit by Bubblefin provides chamber dividers to create dedicated spaces for protein skimmers, refugia, and media. The larger volume supports higher water throughput and enables more flexible equipment placement. As with other DIY kits, measuring the tank’s inner dimensions is essential to ensure a proper fit and avoid filtration bottlenecks. It supports varied filtration strategies and can be adapted to evolving tank needs.
Reefing Art Ceramic Bio Filter Media

Reefing Art ceramic bio filter media provides a vast surface area for beneficial bacteria, supporting ammonia and nitrite removal in sump and canister setups. The product is sold as a box containing multiple pieces, suitable for freshwater, pond, and saltwater systems. Its inert ceramic composition helps maintain stable pH while enhancing biological filtration. The media can be placed in dedicated reactor chambers or filter baskets to maximize contact with water flow and improve overall filtration efficiency over time.
Buying Guide: Key Purchase Considerations
When choosing a sump setup, consider compatibility with tank size, available space, and filtration goals. Look for adjustable water levels to match skimmer height and living refugia needs. Chamber dividers offer flexibility for future equipment changes, while high-grade boards and leak-resistant fittings improve durability. For refugium-centric setups, prioritize wide, accessible refugium sections to support macroalgae and Pod production. Filtration media like ceramic bio media enhance biological filtration without altering water chemistry. Finally, ensure the sump kit’s dimensions align with your tank’s inner width to avoid misfits and water level issues.
Comparisons Across Perspectives
- Size and compatibility: Smaller tanks benefit from compact 10G kits, while 20G Long and 40G Breeder setups provide more filtration space for larger systems.
- Filtration emphasis: Sump kits focus on mechanical and refugium filtration, whereas media like ceramic bio media emphasize biological filtration.
- Upgrade flexibility: DIY divider kits offer customizable layouts but require careful measurement of tank dimensions.
- Maintenance and accessibility: Larger sumps with clear chamber separation simplify maintenance, skimmer access, and media changes.
