Product Description

Size Name:3.5W Panel + Aerator + Battery

Oxygenating your pond is vital for fish and underwater plants, especially when the weather is warmer and oxygen levels drop. This premium 3.5W solar pond oxygenator with battery backup will oxygenate your pond thoroughly without any cost, maintenance or hassle.

The unique feature of this particular kit is the built-in battery backup. The solar panel charges the battery when it's sunny, so your pond continues to be oxygenated even when it becomes cloudy or there's little sunlight. On fully charge battery the pump will work for 5-6 hours.

A mains adaptor is also included so if you prefer, you can charge the battery or power the pump directly from mains power.

Adequate oxygenation will mean that your pond environment remains stable with clean, clear water. This solar-powered pump will ensure that oxygen is delivered efficiently through the air stone provided.

Note: This oxygenator is easily set up in under 2 minutes, with no maintenance required afterwards.

The oxygenator kit arrived promptly, it was safely and conveniently packed. The kit was easy to put together, it took less than 15 minutes start to finish. I then simply plonked the air stone in the little pond, switched it on and left it alone. It`s been sitting there pouring out a vigorous stream of bubbles for a few weeks now. Obviously, at night the batteries run down and the flow stops. But when daylight returns they seem to charge up surprisingly quickly and off it goes again. Even on not particularly bright days.
Very pleased with it so far.

I am really pleased with this. Despite the reviews which said that it only worked in bright sunlight, I have found that even when it is quite overcast, there is still some activity. In fact I could still see a very slow stream of small bubbles in the middle of a black sky downpour this afternoon. In full sunlight, it is like a mini-jacuzzi in my barrel pond! Some reviews say that it is noisy....well it is a pump, so you might expect a little noise, but I found that it was at such a low level that I didn't really hear it unless I focused on it (a low-level clicking sound, but fine). Within two days, my pond water was as clear as glass and the goldfish are obviously happy too, as I have been able to clear some of the oxygenating weed which had really taken over, and they now have room to swim a bit more - I can see the smiles on their little faces from here :-)

After having others, this is by far the best, and most expensive! While the volume pumped is less than a two stone version offered elsewhere, this model has two advantages.
The solar cell will work even in dappled sunlight
The battery charges quickly and keeps it going for an hour or longer after the sun stops shining. On a typical mixed day, this means it is running all the time.
I had a problem at the outset and the supplied provided a new battery box by return and all has been well ever since.

I purchased this item to use in an 80 litre water barrel where we have some goldfish. The barrel is situated in the shade so the solar panel had to mounted so it could see over a neighbours fence to gain a south facing view (photo attached).
With the clear south view in April, the pump will run all day (on not necessarily a sunny day) and for a few hours till after dark.
My only criticism is the pump does make a noise, a hum that can be heard over 10 feet away.
I would recommend this unit for aerating water where it is not possible to get mains electricity supply, it does a good job.

Perfectly good enough. Although it makes a noticeable noise when at full speed (full sun or mains powered) so I'm considering burying it in a sealed container, most of the time it just ticks along discretely even on a cloudy day.
Unless you're after a lot of bubbles all the time, this little pump does just fine as a little oxygen booster while running on solar power alone.

I bought this to aerate a pond which is in the open, but sometimes shaded by trees (not overhanging, just nearby). The solar panel only produces enough power in direct sunlight, unlike those for a couple of cat scarers which charge from just a bright sky.

In direct sunlight the water fizzes andthe fish enjoy the spa effect.
