Greetings fellow fish-keepers! I currently have a 3-gallon Betta tank and I soon want to replace all the decor and gravel in it. I want to switch it up because when I originally got my tank, I put glow in the dark gravel and neon/rainbow/unrealistic colored decorations in it but now as I get more drawn into the fish-keeping hobby, it's starting to look pretty ugly. I want to take everything out of my tank and replace it with natural looking substrate, natural looking decor (driftwood, mini-logs), and even some plants. My problem is that I'm concerned about damaging the beneficial bacteria in the tank. Does anyone have any tips or anything helpful to say to help me through this process without running the risk of hurting my tank's bacteria or water parameters?
