When I set up my tank in February I had no idea that the inches of sand for the substrate was important, so I just dumped in a couple bags of fine, dry, white sand from Petco. I don't know- that might have given me 3 or 4 inches of sand. Since that time I have vacuumed out some sand in a desperate attempt to clean out some of the cyanobacteria (which was mostly successful). Now my sandbed is very uneven- ranging from 1 inch to 4 inches all over the aquarium. SO is this a DSB or a SSB? My main concern is that at some point a disturbance to the deep part would release something toxic. I have two nassarius snails. Thank you for any input you give!
