Recently set up a 46 gallon tank.
Moderate to heavy planting, varied types of plants.
120 watts of lifeglo flourescent light.
12 cardinal tetras.
About half of the water in the tank is from an established tank.
The biological filter is well established.. again taken from another tank. It is set up so as not to disturb the surface water of the tank, to prevent co2 loss.
The plants will take some time to get acclimated, and start producing oxygen. Of course they will need co2 to do this, and I have 2 diy yeast co2 injectors going.
Unfortunately, the fish appear to have used up all of the oxygen in the tank... they started hanging out near the top, and I immediately introduced aeration, and in a short time all was well again.
Of course this means that any co2 I am introducing into the tank is not staying in the tank for long, and the plants will be needing that c02 if they are going to get acclimated and start producing enough oxygen for the fish.
So, if I aerate, the plants die, and if I don't the fish die.
Is there any way to introduce oxygen into the tank without reducing the co2 levels?
Please ingnore my newbishness... this is my first attempt at a planted tank.
