A bubble box is designed to connect to your downpipe (weir connection), allowing water to flow into your sump at a gentler rate. This simple but effective piece of equipment provides several key benefits for marine and reef aquariums:
Reduces Water Loss & Maintains Salinity: By controlling flow, a bubble box reduces evaporation, helping maintain stable salinity levels—critical for reef systems.
Minimises Micro Bubbles: Water flowing through the bubble box experiences less turbulence, reducing nuisance microbubbles in your display tank.
Controls Salt Spray: Prevents excessive salt from spreading outside the sump, reducing maintenance.
Reduces Noise: Smooth water flow significantly cuts down on loud draining sounds from the sump.
Increases Oxygenation: As water gently falls and breaks the surface inside the bubble box, oxygen levels in the water are improved.
How It Works:
Water flows from the weir, through the pipework, and into the bubble box. By reducing splashback and controlling the flow, the bubble box improves efficiency and creates a quieter, cleaner, and more stable aquarium environment.
