i am in the process of redecorating my 75 and want to use sand for the bed. i am just not sure what type of sand to use if i decide to go this route. my question is can i just go to home depot and buy sand or go to the beach and get sand? i plan on keeping a few plectos, a school of neons some bala sharks, i prefer hardy fish cause im not really that skilled at growing them, so i have have something that is hard to kill. any suggestions would be helpful.
