I know you can't put fertilizer in the water of an axolotl tank but can you put fertilized substrate under the sand in your tank or is that bad too? A couple of my plants have turned a little brown and I just want to perk them up a bit. If I can't put the fertilized substrate in with my axie I plan to just put my plants in a fertilized fish tank for a few days/weeks.
