Do they only create waves or do they also oxygen the water?

They can help oxygenate the water by creating water movement and surface agitation.

It creates waves. But if it is aimed at or is close enough to the top, it breaks the water tension oxygenating the water. If you're wanting oxygenation and water movement, get a powerhead that has a venturri.

As the others have said the waves that are produced help to break up the surface of the water. This action helps to facilitate the exchange between the oxygen at the surface of the water and the gas produced by the break down of organics in the aquarium.

Yes, surface movement promotes gas exchange. You won't regret the purchase, it's a good pump.

Well normally when the surface of the water is broken it helps bring oxygen into the water. As least to my knowledge.

The best answer is both. They resist when you push down or out and their buoyancy makes you work harder. They definitely add resistance to your work out.

It does chirps when it is done. There is a line that you fill with water at the bottom and when it runs out, I believe is when it chirps. They do come out perfect every time. It is Awesome. I love it and so does serval of my family and friend I purchased for.

If the surface of the water is moving, then yes. Led lights will give you that shimmer effect, and these are led lights.

They apparently are zipped through on the air currents. They can't get into the net with the fan on, without going through the blades, which all the ones I have seen do without getting killed. However, a few hours of constant air current with no water to drink, and they dry up and die.

Yes they do' but the air is not helium. This is a good pump. It will do the job very fast.

Ozone system has a ozone generator to help kill bacteria in the water. But it only works on "boost" cycle. Just a fyi.

Yes they shoot up water even though there's not a lot of bass.The water shoots up higher the louder you turn it up.

Yes they do. They come with everything you need except for the water to activate it

It sounds like theirs air getting in somehow? If it's sucking all water it shouldn't put out bubbles

Not fully. They've gotten wet and survived on mine. But they ran a little different and noisier after I did.

They are shielded inside with a metal surrounding. Basically they steam with the water. Works great.

Yup, they float. I even threw a couple in our little outdoor kiddie pool and my kid loves it.

They float. I love mine propulsion is greatand they are my main surf rescue fins.

Yup, mine do. They don't end up getting down in to the rest of the water so I don't mind it too terribly much but it does get annoying after a while.

The fountain and filter move the water around, which helps aerate it. Usually if your water is lacking oxygen, it is due to too many fish or too much uneaten food in the water. The filter helps with removing contaminants which while decomposing will deplete the oxygen.

They seem to when they have been exposed to the air. Mine never did when I first opened a bottle but they do seem to later.
