Dissolved Oxygen

I have read quite a bit on different methods for increasing Oxygen levels and in particular O2 ppm in the aquarium for breeding. Interested to see if there are many people achieving 8-10ppm and if so the different ways in which you achieve it.

Kind Regards

There's an article on Oxygen levels in Shane's world.

Simply put, it's about getting surface movement and circulation [so that the oxygenated water moves to where the fish is!].

I bought a chemical oxygen test, but it was totally useless, so without a very expensive digital meter, I have no idea what value my tank is.

Bear in mind that at 30C you will reach 100% saturation at 7.45 ppm, and at 25C, 100% saturation will be at about 8.2 ppm, so the values you're after may be a bit optimimistic.

The best ways to achieve good oxygenation is by......

Having a tank with the largest surface area/volume ratio possible.
Not having a hood or condesation tray.
Providing maximum agitation and turnover of water surface.

I would also recommend not having any bogwood or plants in the tank, as any decomposing material will suck up available oxygen.

Hope this is of some help.
