I have a 50 gallon, moderately planted community tank with pool filter sand for substrate that I’m really beginning to regret using. I’d like to switch it out for a darker colored substrate such as Aqua Soil but I’m not sure where to start or how to go about doing this. I have sterbai Cory so I do not want to use gravel. Is anyone willing to give me some tips or walk me through the process? Thank you. Edited to add: I do have an empty 26 gallon that I could temporarily House everyone in but it would quite cramped. I’m most worried about starting a whole new cycle.
