aquarium bubbler for pond?

[micaaronfl76]

assuming u keep the unit dry can u use one in an 400-500 gallon pond?

There are diffusers you can get for ponds, that will handle larger quantities of water. We have one and use it when the water temps are 80 or over to add more oxygen to the water.

i was just thinking because i have a bunch of old aquarium bubblers to add one just for aesthetics. Wasnt sure if there was any problem with that.

Aquarium air pumps are designed to be used in water no more than about 2' deep. If your airstone is much lower than that, you may not get much air out of it.

I have one from petco and it has 4 outlets and cost less than 30 dollars for 6 years and it still works great .I just protect it and most aerators need protected any way

I have one in my pond and I just only allow the tubing to go down a foot or so and it creates some nice fine bubbles that the fish like to swim through. Then I have the big air pump I bought last year and I will hook that up for a much bigger bunch of bubbles shortly. Just bought some round airstones to hook onto the twelve little stems w/ tubing attached to each one. That way I can use longer and shorter tubing on each stem to provide air to different area's of the pond instead of one giant volcano of air in one spot.

On the pond at the old house I used a medium sized air pump for an aquarium and placed the air stone in front of the skimmer. This added oxygen to the water for the bacteria in the filter, Helped keep food out of the skimmer, and it brought gunk up from the bottom so the skimmer and leaf net could remove it. I used the aquarium pump for two years and it worked great. But like Sissy stated, I also had it protected from rain and the elements. They aren't really designed for outdoor use.

a skimmer by itself will do more to oxygenate the water than a bubbler will. especially an aquarium pump. theyre actually about as effective as you can get for oxygenation.
heres a cut and paste from an article on skimmers and aeration:

The pond skimmer does more than clear the surface of the pond. Pond skimmers increase oxygen levels in ponds helping to further purify the water, and of course provide rich oxygen for your koi and pond fish. Pond skimmers can do as much or more than any sort of submerged aerator, and they do not disturb the surface of the pond, allowing for nice visibility and reflections to be enjoyed from the surface of your pond.
Did you know that most oxygenation for ponds take place by way of the ponds surface area absorbing oxygen directly from the atmosphere. Those air pumps we use that create thousands of little bubbles that rush to the surface of the pond and explode really do very little to oxygenate. For oxygenation to occur those bubble need to have contact time with the pond water so they can give off the oxygen but they move so fast that there is really minor oxygenation that takes place. It is where the bubbles break up the surface of the water that the oxygenation takes place. Well a pond skimmer is constantly and rapidly breaking up the surface of the pond too. Pond skimmers oxygenate at a much greater pace, with more oxygen being absorbed into the water because the skimmer is constantly increasing the ponds surface area.
** the preceeding was a cut and paste from an article by Mike Gannon.

i dont use a skimmer on my outdoor pond. but i do use one on my indoor pond for wintering my fish. i just net by hand outside. but fines and DOCs tend to accumulate in the top layer of water so i built a DIY fines skimmer that does a fantastic job of removing them, any floating solids (fish poo mostly) and aerating too.

( this could easily be ran to a bio filter instead of just back into pond).

We have a skimmer as well. I wouldn't put in a pond without a skimmer at this point. It does go a long way towards keeping the leaves and crud from settling into the pond.

The thing that is nice about the diffuser is that we can turn it on if we go away for any length of time and shut off the main falls. This way, if there are any problems, we won't come home to an empty pond. Several years ago, we had a hose blow and lost about a quarter of the pond before we realized the hose had blown. With the diffuser, this won't happen if we are out of town.

no skimmer but I put the air hose in both of the filters and I really think most all aerators need protected no matter what .I got my other aerator and neighbor bought it from me and now have to get another one I guess .
