cleaning dirty spots on substrate?
i have in certain places, dirty (surface) spots, dark areas os sand where i suppose waste or excess foods build up. my substrate is crushed argonite, and moving it around only clouds up the tank.
a turkey baster wont works well either. the sand isn't awful or putrid, should the sand and microbes get to it in time, or should i get a sand moving detritovore.
my only sand movers are some small nassarius snails
