To avoid anoxic regions, don't use a very deep sandbed. Also, there's a way of running the siphon over the surface of the sand without sucking too much up.
i know im new to it but sand just has mor personality to me . gravel allways looks flat but the sand in my tank forms small hills and dunes and little rifts all over the place because of the current.
my cories love the sand they will dig in and almost bury themselves im tempted to take my other corys out of their gravel tank and put them all in the sand tank
i may put them in my 5 gallon sand tank after it cycles. shouldt be long its usein a used filter
only thing ima use my gravel tank for is my plantign exsperiment
cant use sand in that tank cause its a small acrilic
i just swiched to sand because i have eels. i use very fine sand, which i don't like that much because i can't shuffle without making a mess. but if the sand would be like the one i use for my marine tank, which is not as fine, then that would be great. sand looks fancy. :dance:
