Aquiflor's opinion: Japanese HiBlow air pumps equip the ponds of our most demanding customers: quiet, energy-efficient, and durable. This HP-150 kit comes with diffusers, weighted hose, and a manifold, ready to install.
This HiBlow HP-150 aeration kit includes all the equipment needed to oxygenate a pond with a surface area of 120 to 150 m²: a HiBlow HP-150 air pump delivering 150 L/min, 5 weighted Japanese micro-perforated Air-Aqua diffusers measuring 90 cm, 50 m of weighted hose (10 m per diffuser), an Aquaforte 5-way 9 mm valve (PP tube, ABS/HDPE valves), one outlet per diffuser, as well as the SC214 connection kit and 12 stainless steel hose clamps. Each part has been selected by the Aquiflor team to fit together without modification.
For what volume?
To calculate aeration requirements, we start with approximately 1 L/min of air per m² of pond surface. With its 150 L/min, the HP-150 covers ponds of 120 to 150 m². Depth also matters: the deeper the diffusers are placed, the more pressure the pump must overcome and the more the actual flow rate decreases. If your pond is deep, heavily stocked (koi, sturgeon), or at the top end of the range, choose the larger kit or send us its dimensions: we will advise you.

Why a HiBlow pump?
HiBlow pumps propel air using an electromagnetic diaphragm mechanism: no oil, no lubrication, and very little vibration. They are designed for continuous operation and are used by Japanese koi breeders. The HP-150 delivers 150 L/min of air. The HiBlow HP range operates between 31 and 45 dB according to our pump data sheets.
Each Air-Aqua diffuser combines an AISI 316L stainless steel weight and a micro-perforated membrane held slightly above the bottom: very fine bubbles, good mixing, and a diffuser that stays in place.
Commissioning
- Place the pump in a sheltered area, on a stable and ventilated support, ideally higher than the water level; otherwise, install a non-return valve. Never place it underwater.
- Connect the pump outlet (Ø 18 mm) to the valve using the SC214 connection kit.
- Cut the weighted hose into 5 lengths of 10 m and connect each valve outlet to a diffuser. Secure each end with a stainless steel hose clamp.
- Place the diffusers on the bottom, away from the filtration pump's intake.
- Turn it on, then adjust the valves to achieve even bubbling. Do not close several outlets at the same time: too much back pressure will wear out the pump diaphragm.
Winter aeration
In winter, place the diffusers halfway up: the bottom keeps its water warmer for resting fish, and gas exchange continues at the surface.
Maintenance throughout the seasons
The pump requires no lubrication. Regularly check the air intake filter foam and clean the diffusers if the bubble flow decreases. Diaphragms and valves are wear parts: our experts recommend replacing them approximately every 5 years. For the HP-150: HP-150 / HP-200 diaphragm and valve set or HP-150 / HP-200 diaphragm set. All parts are grouped on our HiBlow guide.
Aquiflor's tip
Keep a spare HP-150 diaphragm and valve set: in case of wear, you can replace the parts without delay and the pond will not be left without air, especially in summer when warm water naturally contains less oxygen.
