Hi,
I was posting as you were replying to Gerry, so you kind of answered the main questions. It is a conversation.
I keep tanks with inert substrates and they are just fine, they simply require a little different strategy. Frankly, the black gravel is dramatic, a very good look. Rather than switch out substrates, think pots with enriched soil and Osmocote.
The lack of CO2 is going to be a challenge, though not insurmountable.
How are you set for water changes? I am guessing the tank is not drilled.
I think you are going to need to back off the light, removing bulbs, adding shade cloth or a screen. Perhaps floating plants, or Tiger Lotus, even aponogeton to get leaves on the surface to cut the light.
How is Miss Odessa these days?
