Aquarium Advice FINatic
I have FINALLY begun injecting co2 into my planted tank.
My kh/gh are both 2.
I am trying to do this without additional buffering if I can since I have softwater fish/plants.
Oh and running my controller without the co2 plugged in told me that my co2 is 6.5 in the morning (after the plants have been on lights out all night) and 6.7 in the evening.
I calculate that by running the controller at 6.4 I am adding 12 ppm of co2 for a total of 16 ppm.. The charts show more .. but they also seem to say I have 13 ppm naturally which makes little sense.. so I think they must be at least 8 ppm off from other acids in the tank. Instead of reading the chart exactly I am instead subtracting 8pmm from the final result.. Oh and a great chart with moveable rulers ... http://www.dennerle.de/HG07UG07.htm
So, in a tank with Apisto cacs, soon to be evicted rummynose tetras, soon to be added pencil fish, otos, a couple of bristlenose plecos and some featherfin rainbows, how low a ph can I maintain?
I'd love to get the co2 concnetrations at 6.3 or 6.2 if that is okay for the fish. The charts say 6.3 gives me a perfect 30 ppm of co2, but if I subtract 8 ppm from the total.. the ideal co2 levels seem to fall at ph 6.2.
I can buffer and bring the co2 concentrations UP, but since the co2 doesn't seem to be bouncing around any, I'd like to try to do this without additional buffering.. I can be talked out of this if I am taking too great a risk.
thanks!!!
