Installation and maintenance

The Laguna 24 installs in minutes thanks to its integrated rear filtration. Place the filter floss and activated carbon in the rear chambers, connect the return pump, and fill with saltwater. The 2-gallon filtration chamber offers enough space for a heater, a compact skimmer (Reef Casa Bubble Beam Mini), and a bacteria block. Maintenance: change floss twice a week, carbon every 1-2 weeks, and perform a 25% water change every two weeks.

Reef compatibility

With 24 gallons, the Laguna allows you to keep a variety of corals including SPS, LPS, zoanthids, and soft corals. The higher water volume provides more stable parameters than nano aquariums. The Laguna is suitable for breeding clownfish pairs, dwarf wrasses, gobies, and a full cleaning crew. Its shallow format maximizes light penetration, ideal for demanding photosynthetic corals.

Frequently asked questions

Is the Reef Casa Laguna 24 the largest Reef Casa aquarium?

The Laguna 24 is the largest shallow model in the Reef Casa range with 24 gallons. It shares the same 22" x 20" footprint as the Tide 12, but measures 12 inches high instead of 7, doubling the available water volume.

What lighting should I choose for a Reef Casa Laguna 24?

The Manta 75W by Reef Casa is the recommended lighting due to its 24" x 24" coverage which perfectly matches the Laguna's footprint. For demanding SPS, some aquarists combine the Manta with an AI Prime or a Radion to increase light intensity.

Do I need a protein skimmer with the Laguna 24?

A skimmer is not mandatory for a 24-gallon aquarium, but it is highly recommended to maintain crystal clear water and reduce nutrients. The Reef Casa Bubble Beam Mini is designed to fit directly into the Laguna's rear filtration chamber.
