An experience in anaerobic metabolism

Recommended Posts

I decided to experiment with some anaerobic metabolism by trying to grow anaerobic bacteria laying down spiral bio rods in the substrate, unsure if it will work but seemed like a good idea to me.

Anyone else tried to do something similar?

Interesting idea, how are you planning on measuring if it is effective?

Ha! you ask the difficult questions.

I was thinking of capturing a baselined of the tank in 6 months time, then take them out and see what happens over a month or two after that.  If there are any interesting differences, I will repeat it a couple of times to see if there is a correlation between any change in tank chemistry and when the rods are in or out of the tank.

What do you think, any suggestions on how I could test it?

All other things being equal (fish stocking, plant stocking, water changes etc.) comparing nitrate readings from when the rods are in and out is probably as good as you'd get.  It won't get you published in a scientific journal but as a home experiment it'll be interesting to see what happens.

Do you think having the rods sitting on the substrate will be enough to anaerobic conditions or are you going to bury them under the substrate?

@Skippy - thanks, good advice. They are burried, see the photo of the aquarium in the other post. Although I also think the depth within the substrate might also affect the results - so I might get some more sand to top up the levels. Well until the cichlids decide to dig them out.
