So, I've been thinking about what to do with the 20 gallon that I custom built into an AIO with customer stand and canopy. I've been debating on a freshwater planted tank with an amazon theme or to try again as an SPS tank. My fear with this is, I had it up as a reef tank twice and the green hair algae took over even though all my params checked out. What do you guys think I should do? I do still have my rock. Dried out by now. I plan on soaking or boiling it before I put it back in the tank.
