Effectively aerating a pond will help prevent algae growth, reduce muck and decaying organic matter, and provide a healthy environment for fish to thrive. While there are other conditions to consider, the depth and size of the pond are the two main factors in choosing the right air pump.
The pond depth will directly impact the amount of air that is diffused in the water. Depth creates back pressure on the air pump—the more back pressure, the less oxygen is diffused into the pond. Click the following link for more details on what causes pressure in an aeration system, and ideas to limit the pressure and maximize aeration.
Below are general recommendations for choosing a pump based off the size and depth of a pond.
* for any depths greater than 6’, you may want to consider bumping up to the next size to offset the loss of air from the increase in pressure
*If breeding specific types of fish, we would recommend consulting with an aquatic specialist before selecting a pump as certain breeds require different levels of oxygen
*If you have an odd or kidney shaped pond, it may be advisable to contact a pond distributer for guidance as you may need multiple diffusers to properly mix and aerate the whole pond
*As mentioned in the link above, diffuser type and pipe size may also impact the size of the pump needed

aerator pond 1/2 ac max depth 9ft
I’d probably recommend either the HP-100LL or HP-120LL at 9′ depth. Depends on how many diffusers you have. If you have 2 then the HP-100LL should be fine. If you have 3, then I’d go with the HP-120LL.
Would like a price on 3ea. Ep-80’s
We make either an HP-80, XP-80, or WG-4 which all have equivalent air flow. Please contact our info box and we can steer you to a distributor. info@hiblow-usa.com
2 acre pond with 2 diffusers and max depth of 12-15 ft?
Hi BJ- First, I wouldn’t exceed 10′ in depth with our aerator. Will it run at 12′? Yes, but the air flow will be minimal, and the diaphragms will rupture faster than normal. If you get the pump to 10′, I think you would need more than 1 aerator and definitely more than 2 diffusers to mix the pond. Perhaps you could buy 2 HP-120LL’s with 2 diffusers attached to each. We are launching a new adjustable height diffuser in which you can raise the diffuser 2.5′ off the bottom. Check back in August for more information.
We have a HP-100LL with 2 lines. It’s on 8-14 hours/day depending on the season. We live in KY, electric is 13cents/kwh. Do you know about how much it costs to run per year?
Thanks
Hi Lorinda! The HP-100LL runs on about 75 watts of power (like an old incandescent light bulb in our living rooms). Running on average of 11 hours per day, your estimated cost per year would be $40. Energy efficiency is one of the greatest advantages of our aerator!
