Why not to use sand

so your always going to get some then. any detritus will have proteins etc which are carbon based..

Proteins contain sulfur as well as carbon. Fish is high in sulfur as are eggs hence the strong smells associated with each as they age.

By stirring do you mean just stirring quickly or do I need to move all the decor and put them back in after stirring?
Take it slow when you stir. You don't need to stir around in a hurry. Use chopsticks or fork or you could always use the trumpet snails to help with the process.

Unless your decorations have holes in them to allow circulation of air underneath, then the decorations need to be moved around as you stir to prevent dead pockets from forming below.

Every living thing has anaerobes in it, not just aerobes. Although in humans, anaerobes are often responsible for sinusitis, tetanus, dental absesses and many other health problems, they also play an important role in body functioning such food digestion. My point here is, that not all anaerobes are as bad as this thread made it sound to be nor is it that living beings do not have them in them which is one of the few points to consider.

true, but not all proteins contain sulphur. only those that contain sulphur containing amnino acids in their R group (like Cysteine) will.

this thread is turning into a biochemistry refresher lol
That's what makes this thread scientifically interesting.;)
 
wc and tank maintenance is addicting
its one of the factors that keeps me in the hobby

i use both sand and gravel
stiring sand and vac the gravel is fun for me
 
Okay fellas, I emailed this concern to my bio professor I'm doing undergrad research with.

this is his reply :


Hey,
Great question. I have mud on the bottom of most of the tanks in 101,
and in fact, it does trap anaerobic deposits. Sand does a fair job of it
too, especially the fine stuff. Whenever I clean out, or stir, one of
these aquariums, I get a little whiff of hydrogen sulfide. so, yeah.
thing is, I have never ever known fish to be harmed by it. Can you
imagine? In the wild, if a little bubble of swamp gas killed fish?
I don't know what you are keeping, but the usual aquarium species can take a
little harmful gas.
