many of us here either use childrens playsand,or pool filter sand.
either one is ok,i don't have experiance with the pool sand,however
i have play sand,i can not tell you how much you need to wash it ,as you need to do it over and over and over again,and a few more after that....
i have gravel at the back of the tank,and sand at the front,as i intend to keep
plants....water lettuce..for the top...it floats
vallis...to name a few.
