Sand has its pro's and con's.
Ive had it and still have it in tanks, stay under one and one half inch thick or you will have anaerobic problems. Poops doesnt settle in quickly either, it pockets and sticks to still spots in the tank, also you have to stir it unless you have burrowers and inverts to do that job, but it has to be cleaned by hand still.
Here are my three sand tanks.
This one was perfect, never had any issues
this one got the sand removed.
and now looks like this
And last but not least my 40g rio negro biotope.
Sand isnt bad if you know how to manage it, I didnt use any ferts in the first tank and well all those plants are in the 3rd pic now( got rid of the tank).
If you have melting plants or plants that melt, do not use EXCEL it will melt them off completely.
