Hello, I just finished cycling my tank but I'm a bit disappointed with how it looks. When I first started this project I did not intend on making as big of an investment but at this point, I've spent so much on the lighting, filtration ect. that I might as well have purchased a more quality substrate (the one I have is hard as rocks and my plants don't seem to be entirely fond of it). Can I do like a tank reset so to speak? I want to remove everything and redesign it but not have to go through the same cycling process. I have 8 tiger barbs and a pleco in this tank as well. Should I keep some of the water or does that not matter?
