Aquiflor's opinion: Japanese HiBlow air pumps equip the ponds of our most demanding customers: quiet, energy-efficient, and durable. This HP-120 kit comes with diffusers, weighted hose, and a manifold, ready to install.
This HiBlow HP-120 aeration kit includes all the equipment needed to oxygenate a pond with a surface area of 100 to 120 m²: a HiBlow HP-120 air pump with a capacity of 120 L/min, 4 weighted Japanese micro-perforated Air-Aqua diffusers measuring 90 cm, 40 m of weighted hose (10 m per diffuser), a chrome-plated Aquaforte 4-way manifold with 9 mm outlets equipped with a valve, one outlet per diffuser, as well as a 19 mm connection hose (5 m, to be cut to length) between the pump and the valve, and 10 stainless steel 11-16 mm hose clamps for the weighted hoses + 2 stainless steel 18-25 mm hose clamps for the 19 mm connection hose. Each part has been selected by the Aquiflor team to fit together without modification.
For what volume?
To calculate aeration, Aquiflor starts with approximately 1 L/min of air per m² of pond surface. With its 120 L/min, the HP-120 thus covers ponds of 100 to 120 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, very heavily stocked (koi, sturgeon), or if you are at the top of the range, choose the higher-end 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 to run continuously and are used by Japanese koi breeders. The HP-120 delivers 120 L/min of air. The HiBlow HP range is 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 out of the rain, on a stable and ventilated support, ideally higher than the water; otherwise, install a non-return valve. Never underwater.
- Cut the 19 mm connection hose to the required length and connect it to the pump outlet (Ø 18 mm) and the chrome valve inlet (Ø 20 mm). The assembly is simple: pump → 19 mm hose → chrome valve → 9 mm weighted hoses to the diffusers.
- Cut the weighted hose into 4 lengths of 10 m and connect each valve outlet to a diffuser. Tighten each end with a stainless steel clamp.
- Place the diffusers on the bottom, away from the suction of the filtration pump.
- Turn it on and then adjust the valves to obtain even bubbling. Do not close several outlets at the same time: too much back pressure wears 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 foam of the air inlet filter 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-120: HP-100 / HP-120 diaphragm and valve set or HP-100 / HP-120 diaphragm set. All parts are grouped on our HiBlow guide.
Aquiflor's tip
Keep an HP-120 diaphragm and valve set on hand: in case of wear, you replace the parts without waiting and the pond does not remain without air, especially in summer when warm water naturally contains less oxygen.
