Anyway, after a good cleaning, a bit of bleach and a thorough rinsing I am ready to move on to the next stage: substrate! Which brings me to my question; Will any brand of play sand do? Which brand of play sand is best? I went to Home Depot to look for play sand, they had very few options and I didn't like most of them. I couldn't tell exactly what each brand of sand looked like (the packaging wasn't see-through, I had to examine what was leaking out of the bags) but they all seemed to be pretty rough/coarse. The sand I have is more rounded/finer and my crabs really seem to like it. In an article about substrate from the Crab Street Journal there is an image comparing three types of sand but it does not say which one is ideal. My sand resembles the sand on the left and the stuff at Home Depot looks like the sand on the right. The article also says that "sand that is too coarse can cause harm if lodged in the shell". Is this true and, if so, how coarse is too coarse?

Thank you in advance for your advice.
