Today I bought a new tank, 5.5 gallon. I already have my betta in a different tank but I’m planning on moving him to the one I bought today. I got aquarium sand, dumped it in my tank, added water but it was really clumped together and floated at the top so I kept stirring and emptying the water out. Once I finished, there were very little (small) clumps of sand together but my water was cloudy. What should I do?
