AllPondSolutions Pond Air Pump, Garden Outdoor, 16 Outlets Ultra Quiet Oxygen Pump, for Large Koi Ponds up to 50000L – Includes Outlet Adaptor. Low Power 90w

If you have a large garden pond and need better aeration across it, then this is the pump for you. I was inundated with mosquitos due to my water not moving enough, but installing this air pump with air stones after cleaning out the pond and run made a huge difference. It not only stops mozzies, but keeps the water oxygenated, especially in warmer conditions, which is great for your fish. You will need air line and stones to attach to the pump (get good quality items and sinking air line if you can) but once set up, it will be a wise investment.

Bought this to replace a blagdon pump that was running a number of large airstones in the pond. This pump is way more powerful and does literally boil the water…. lol. When the replacement pond arrives, it’ll have no problem running the aerated bottom drain. Not quiet, but wasn’t expecting it to be.
