Hey John, Rex can be a little blunt at times but reading a number of his posts I think he means well. It's just frustrating sometimes to read something that just looks wrong to you. I can assure you that many of us manage to raise someone elses hackles when we post here. I know I've gotten someone's ire up recently. But I also know that the desire to help other people have stable healthy tanks is the driving force of the discussion and the immediate results of overly forceful remarks like mine will meter out into better discussions not bad blood.
Ok, did you know that a plant grows new root hairs every day?
The substrate of a planted tank has a lot more O2 in it than a plantless aquarium but it is not fully aerobic, infact it changes over the course of the day.
Having some anoxic conditions occur in the substrate is important to the process of releasing nutrients in the form the plants need.
Gasses that form in the aerobic substrate, CO2
Gasses that form in the anerobic substrate, CH4, N2 and N2O, H2S, CO2.
Anyone want to add to the lists?
