LoveMyPlatys Posted May 25 Share Posted May 25 Someone started a topic on changing substrate but different situation. I’m not sure if I’m supposed to add my dilemma to that discussion or start a new topic so starting new. I have a 20 gallon with gravel that I want to put sand in. The gravel is from Menard’s and has been in my tank since I started fishkeeping in January. I bought pool filter sand at Menard’s and washed this week. Others online say this sand is safe but I’m a little nervous. I can’t afford expensive aquarium sand so considering this alternative. My big question is how in the world do I change from gravel to sand with all those live fish in there? Is there a way to minimize debris and dust? And is it a good idea? And how do I make sure not to kill the good bacteria? I have a hang on back filter. Link to comment Share on other sites More sharing options...
