I hope your new plant choices work well for you. I will say that if they don't you can still change out your substrate WITHOUT another tank. I just went to Home Depot and got a 33 gallon rubbermaid container and used my tank water and moved my fish over into that. (My thread is 126g at bottom if you want to read the story.) I put my new soil in. I even had to leave my fish in the container for over a month and I only lost 4, 2 ottos (they aren't a hardy fish) and 2 khuli loaches who committed suicide. Since I used ADA AquaSoil and had to wait for it's cycle I couldn't put my fish back in right away. You could do it in a day. Your fish would be fine. Anyway you have a plan B if your new plants don't work.
