Alternative ways to provide oxegyn


Hey,

I am getting tired of air stones and I am looking for a good way to distribute oxygen to the tank. Does anyone have any ideas on other good alternatives to air stones? Money isn't a real issue here but I would like it to be aesthetically pleasing if possible.

If you have enough surface agitation, there's really no need for an air stone in my experience.

Unfortunately I don't have a lot of surface agitation any suggestions?

Depending on the size of the tank, you can add a small power head or two just to circulate the water. This will greatly increase oxygen.

A spray bar is another alternative.

Ya know, we tend to put something in our tanks here on this forum that generates oxygen in substantial amounts... What we call it is escaping me, though...

Oh! That's right! Plants!

Touche good sir , I just like to add extra oxygen to the tank as the oto's and the panda garra's like the extra oxygen. I will find another way, do any of you know if there are any powerheads that you can attach the airline to?

BUBBLES

do not mean oxygen.

Air pumps are pumping pretty close to 80% N and 20% O and a trace of other things.
These gases do not really enter the water unless the tank is WAY deeper than any private aquarium I have seen. (Perhaps the 2 story high public aquariums...)

Air pumps "add oxygen" because the bubbles drag some water with them, from the bottom, rising to the surface. Water from the bottom may be low in O2 and high in CO2 (in a non-planted tank). This water sheets across the top, and the rippling means more surface contact with the air. When in contact with the air the water gives up the excess CO2 and picks up more O. Then this water sinks because more water is rising to takes its place.

To improve the oxygen level without an air pump is a piece of cake:
ANYTHING that creates better water circulation will help, and the best help is a water pump (power head, Koralia style or filter) that creates more surface movement.
In ponds and small lakes they will put a pump in the water that shoots the water from the bottom vertically, perhaps to fountain, or perhaps simply to ripple and flow across the top of the lake. This is called a flume. HIGHLY effective way to oxygenate the lake water.

Other ways to increase to contact between air and water is to spread out the water such as a stream or water fall. Not very practical indoors, though.

Many Loaches and Cats, and quite a few other fish come from shallow, fast moving water that is relatively cool. Hillstream Loaches being an extreme example. White Cloud Minnows, some Danios, certain Plecos, are some other fish from this sort of setting.
These fish may have poor oxygen coping ability and require very high oxygen levels in the tank.
Keep the water cooler. Cool water holds more oxygen. Do not mix warm water fish and cool water fish.
Keep the water moving. 20x the tank volume per hour is a minimum for these types of fish. This much water movement can be from a combination of filter and power heads. The surface should ripple pretty well.
Keep these fish in a wide, long, but shallow tank. Not a particularly deep tank unless you make a really good circulation system. Tanks like 'Long' and 'Breeder' are generally better than 'Show' or 'Tall'.

I have an ancient powerhead with the venturi nozzle, but I am not a fan of using bubbles/surface agitation for oxygen addition. I have found much higher success with over planting the tank. In doing so, I don't have to worry about gassing my stock either. Plants are the great equalizer of my tank.

Plants bro. A heavy planted tank produces good bit of air. In my 29g I have NO filter NO air stone with just massive amount of plants and fish are doing great. I even had my gourami pair pop out a bunch of babies. But another key is keep up with water changes.
