Dead spots

[Tropjunky]

Recently i've heard a lot about `dead spots` in sand. what are they and why should i care? I've had sand in my tank for about a year and there's been no problems so far.

So back to the point what are they and what do they do?

Places where no water current reaches and are often places where dangerous gas pockets can build. IMO, anything under 2" shouldn't be a concern as there's not really enough depth for the pockets to form.

thanks.

anyone else wanna explain in more detail

dead spots are just another name for stagnation in sand (can happen in mud or gravel-but not as much in gravel as there are more 'holes' for the water to flow through). It is not good because bad bacteria can cultivate there and cause disease in your fish. What is needed to prevent stagnation is oxygen/water to flow through the sand. I also heard that plant roots will cause oxygen to circulate but I'm not sure how it goes or if it's true...?

Snails and digging fish or animals can also prevent the pockets.

i have no idea wot ur talking about

stagnant = no movement (ie. no water flow)

Where there is no movement, bacteria builds up, as the others have explained.

exactly so it you dont want to run a chop stick through your tank you should buy some banjo catfish, (about 1 to every 10 gal. you wont see them much and they only get about 1.5 inches, very interesting fish for only 1.50$)

Banjo catfish eh...? Can they dig 2 inches deep too- if they can that would solve a lot of my problems...
Are they comunity or agressive??
