A few years ago, a barebottom tank is the usual recommendation for keeping Axolotl. I always thought it felt a bit unnatural and set out to try using different substrates. After 2 years with ControSoil Powder planted aquarium substrate, I can say that while it appears safe for Axolotl, it does have the problem of disintegrating over time. In the future, I would probably go with sand and plant stem plants in pots, or simply rely on bare roots plants like Anibus, floating plants, and house plants that are abovewater.

One interesting experiment I did with this tank is to use Sweet Potato. It has been wildly successful in terms of nutrient export as well as aesthetic, I could not be any happier!
