Aquiflor's opinion: Japanese HiBlow air pumps equip the ponds of our most demanding customers: quiet, energy-efficient, and durable. This HP-80 kit comes with diffusers, weighted tubing, and a manifold, ready to install.
This HiBlow HP-80 aeration kit includes all the equipment needed to oxygenate a pond with a surface area of 60 to 80 m²: one HiBlow HP-80 air pump with a capacity of 80 L/min, 4 weighted Japanese micro-perforated Air-Aqua diffusers measuring 60 cm, 40 m of weighted tubing (10 m per diffuser), one chrome-plated Aquaforte 4-way manifold with 9 mm outlets equipped with a valve, one outlet per diffuser, as well as a 19 mm connecting tube (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 tubing + 2 stainless steel 18-25 mm hose clamps for the 19 mm connecting tube. Each part has been selected by the Aquiflor team to assemble without any modifications.
For what volume?
To calculate aeration, we start at Aquiflor with approximately 1 L/min of air per m² of pond surface. With its 80 L/min, the HP-80 thus covers ponds of 60 to 80 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 if you are at the top 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 to run continuously and are used by Japanese koi breeders. The HP-80 delivers 80 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 check valve. Never underwater.
- Cut the 19 mm connecting tube to the required length and fit it onto the pump outlet (Ø 18 mm) and the chrome valve inlet (Ø 20 mm). The assembly is simple: pump → 19 mm tubing → chrome valve → 9 mm weighted tubing to the diffusers.
- Cut the weighted tubing 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 filtration pump's suction.
- Turn it on, then adjust the valves to obtain uniform bubbling. Do not close several outlets at the same time: too much back pressure fatigues 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 on 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-80: HP-60 / HP-80 Diaphragm and Valve Set or HP-60 / HP-80 Diaphragm Set. All parts are grouped on our HiBlow guide.
Aquiflor's tip
Keep an HP-80 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.
