I just got a 40B from PetCo during their sale and am in the process of setting it up. question about the Miracle Gro Organic Potting Soil, did you just dump it in and add the sand substrate or did you do any preparation to the potting soil?
edit: also, where did you get the clip on CFL's and what is the rating on them? ie: 6,500k? seems cheaper than LED's/T5 route
