I used the poor mans method. I set up my sump first (40 gallon berlin style) I used a gallon size container of the "mineral mud" and I think I used a bag of the aragonite but I cant remeber for sure and I used a bag of sugur sand then I started getting my sand from the beach. I went to an area that is not a real touristy area in the shallow water, all the sand in the area was made up of broken shells so its pretty varried but the top layers are have a medium grain size id say definately not fine. I think a cucumber would have trouble eating in it. when I got my engineer gobies sugar sand was the top layer and they never dug. that sand did seem like it would be pretty hard to dig in but then when I put the "beach sand" in the tank they started digging within a few days. I started adding beach sand about a week after I got the gobbies. the main tank is a 47 bow with nothing but "beach sand" about 3-4"
