Sand thickness

[anna]

Was just wondering what is the maximum thickness that the sand should be when you have live plants in the tank? I read somewhere that the root systems of live plants help prevent those bad air pockets so was curious if the max thickness can be upped or not?

yea its true that root systems help prevent air pockets. i would have it about 4-6 cms thick. it will take at least 5 plants scattered throughout the tank to prevent air pockets in a 3 ft. how big is your tank?.

You can take large rocks and put them over plant roots; this will help keep them anchored.

Am getting a 3ft soon. Atm I am keeping my axies in a plastic underbed storage container as my 2ft has some major problems and I cant keep conditions stable enough. Stupid tank!
