Okay for all of my fish keeping life(2 or 3 years) I have used gravel, but I'm about to do a planted tank, and I was thinking about using sand, however I have some questions first. How do I clean the sand? What kind of sand do you recommend?(The only places I can get sand from are Petco, and Petsmart, well the only fish places). I will be using HOB filters. Please help me.
