After having my NPT tank go toxic I have gone back to gravel, small smooth river stone type. What plants can I grow in this? I have anubias, java fern, java moss, banana lilies, and a crypt.
I wouldn't mind adding ecocomplete in the back area but afraid of another huge mess. Will jungle vals work? I guess I'm trying to avoid root feeders at this point unless they can be potted.
Hi psalm, good to see you. The breakdown in organics is why I never use straight potting/topsoil, I always mineralize it first.
A good mineralized topsoil, ecocomplete, oildri, SMS, Turface, fluorite, etc, won't have a breakdown process that will foul up the tank water, so don't be too afraid to use them.
If you do decide to go with stones, you still have several options. Vals will grow in just about anything, just add some root tabs or liquid ferts every now and again. Java fern, anubias, java moss are all good plants that grow in most anything as well.
If you really wanted you could leave something like crypts potted, they'd just be constrained to the pot area.
