Aquiflor's opinion: Japanese HiBlow air pumps equip the ponds of our most demanding customers: quiet, energy-efficient, and durable. This HP-200 kit comes with diffusers, weighted hose, and a manifold, ready to install.
This HiBlow HP-200 aeration kit includes all the equipment needed to oxygenate a pond with a surface area of 150 to 200 m²: one HiBlow HP-200 air pump with 200 L/min capacity, 7 weighted Air-Aqua micro-perforated Japanese diffusers measuring 90 cm, 70 m of weighted hose (10 m per diffuser), one chrome-plated Aquaforte 8-way 9 mm manifold with valves (7 outlets for the diffusers, one spare outlet), as well as a 19 mm connection hose (5 m, to be cut to length) between the pump and the valve, and 16 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, we start at Aquiflor with approximately 1 L/min of air per m² of pond surface. With its 200 L/min, the HP-200 thus covers ponds of 150 to 200 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 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-200 delivers 200 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 fit it onto 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 7 lengths of 10 m and connect each valve outlet to a diffuser. Tighten each end with a stainless steel clamp.
- Arrange the diffusers on the bottom, away from the suction of the filtration pump.
- Turn it on, 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-200: 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 an HP-200 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.
