Why do you need the aeration? Enhanced Oxygen LevelsMaintains dissolved oxygen (DO) above 5mg/L, critical for koi respiration, meta-bolism, and stress reduction.Prevents hy-poxia during hot summers or icy winters.Improved Water QualityBreaks down organic waste (fish waste, uneaten food) through aerobic bac-terial activity.Reduces to-xic am-monia and nitrite buildup by promoting nitrification cycles.Al-gae SuppressionLimits nutrient availability (phos-phates/ni-trates) for al-gae growth by accelerating organic decomposition.Disrupts stagnant water conditions that favor al-gal blooms.Thermal Stratification ControlEliminates temperature layers in deeper ponds, ensuring uniform water conditions.Prevents "de ad zones" where oxygen-depleted water accumulates.Fish Health & VitalityStrengthens im-mune systems, reducing susceptibility to para-sites and inf-ections.Supports vibrant coloration and active behavior in koi. DUAL-FUNCTIONAL - Safe & durable for 24/7 use. Keep your fish happy throughout the year Why do you need aeration in winter? Winter Survival Support Maintains ice-free openings for gas exchange, preventing to-xic gas buildup (e.g., me-thane, hyd-rogen sul-fide). Preserves a stable thermal refuge (2–4°C warmer at depth) for overwintering. Energy Efficiency Reduces reliance on high-wattage de-icers in cold climates (30–50% energy savings). Extends equipment lifespan by preventing ice-related damage. IMPORTANT - Winter Operation! During the winter, move the air stones to HALF your maximum depth. This will help reduce ice formation and keep a "pocket" of warm water for your fish at the bottom of the pond. Easy-to-Clean Rubber Diffuser Super strong, diffuse rich bubbles and very easy to clean comparing with the air stones. Self-sinking Weighted Airline This heavy duty rubber airline is easy to hide and sinks to the bottom to keep your air diffuser in place. Hose Clamp A hose clamp connects the airline and air diffuser, making them super tight during use. Air Flow Regulator It is easy to adjust the air flow of the pond aerator with a solid air flow regulator.

DUAL-FUNCTIONAL - This pond air pump can not only work as a pond aerator, but also helps prevent ice formation in the cold winter months, ensuring your koi have a ventilation hole for breathing!
PREMIUM QUALITY GREAT SERVICE - As we've been supplying to big brands for years, we ensure the customers of premium quality and 7/24 response.
DIAPHRAGM REBUILD KIT - If your air pump stops working because of the breakdown of the diaphragm, you only need to replace the diaphragm to make your machine work normally. Search code "B0C8MMWYPF" to get it.
The product arrived fast, was well packed and in perfect condition. While there were no assembly instructions it became quickly obvious how to plug the components together, we had it in our koi pond within minutes. The unit is very quiet and small so visually unobtrusive as well. We have 24 koi most over 24” long in our 3,800 gallon koi pond and while the pond already had great filtration and surface agitation from robust fountains and spitters we felt the augmentation of underwater aeration would allow our filter to operate more efficiently and the added oxygen would be effective for boosting our koi’s immune system and be helpful in maintaining good water quality in the winter months. We are very pleased with the purchase.
