i have just upgraded my 72g to a 120G and feel the need to increase the depth of my sand bed. I have recently returned to the hobby but when I first started doing this a few years back the rage was Southdown Sand from HD. Doesd anyone know if there is an equivalent today?
I need to purchase RO DI unit - what would you recomend? I have a RO unit under the sink (was there when I moved in) with a tank. I would like to remove this unit and fit the new unit to the storage tank
