Bought this single Solar Oxygenator Air Pump with Battery Backup about 1 month ago for my medium size pond and it's far exceeded my expectations, on a mixed sunny/cloudy day the sun had gone at 4pm and this was still going when I checked at 8:30pm, I think it needs full sun to charge up initially but it's an excellent addition to my pond.
Solar oxygenator
Only recently bought but is running very well in small fish pond.
Impressive
Powerful and creates a great whirlpool for the fish even when no sunshine. At 7am , cloudy and it was going like the clappers.
Solar Oxygenator Air Pump with Battery Backup
for the price this bit of kit is brilliant, it is more consistent than any other air pump we have had basically the battery backup smooths out the cloud cover and lets it run for longer we needed this as we have 20 Shubunkin which are well pleased with the results :)
