Pond Destratification for Year-Round Fish Health The Atlantic Water Gardens Deep Water Diffuser is designed to sink to the bottom of your pond and release a fine column of air bubbles that creates a complete circulation loop from bottom to surface. This destratification process is the most effective way to maintain uniform dissolved oxygen levels throughout the water column, preventing the dead zones that form in warm, still Canadian summer conditions and in ice-covered ponds in winter. Why Bottom-Mounted Diffusion Matters When air is injected at the bottom of a pond, rising bubbles carry cold, oxygen-depleted water upward while pulling aerated surface water downward. This convective loop eliminates thermal stratification — the condition where a warm, low-oxygen layer sits above a cold, potentially toxic layer of decaying organics. Koi and goldfish in destratified ponds show improved feeding response, faster growth, and lower stress, especially during extreme Canadian summer heat above 25°C (77°F). Placement Weighted for bottom placement Bubble Type Fine bubble / micro-diffusion Tubing Connection 3/8" barb (standard airline) Compatible With Typhoon Air Pumps, TPD aeration cabinets Safe For Koi, goldfish, turtles, aquatic plants, wildlife How to Use Place the diffuser at the deepest point of your pond. Connect 3/8-inch weighted airline tubing from your Typhoon or cabinet compressor to the diffuser inlet. Start the air pump and confirm bubbles are rising in a uniform column. For ponds deeper than 1.5 metres (5 feet), use at least the 30 LPM Typhoon model. Replace diffuser membranes when bubble patterns become uneven. Safe for all pond fish, plants, and wildlife. Ideal for Canadian koi ponds and water gardens over 1 metre deep where thermal stratification is a seasonal concern.
