Hello everyone. The fateful day has come when I have to move my aquariums to my new home. I've got the moving procedures down, not worried on that end. But I figure since I would be removing and replacing everything I would change the gravel to sand. I decided on pool filter sand per many statements saying it was a better choice. My question is, did I get the right kind? It is all the hardware store had so I'm hoping it is. Here's pictures of the front and back.
