Who Gives A Fish Forums

I've heard Anubias can yellow if they're not getting enough CO2. Even with Excel, it might not be enough. Have you considered a CO2 system? It's a bit of an investment, but it could help.

That's a wild take, but it makes sense. Plants need some nutrients from fish waste. OP, how stocked is your tank?

If you're not ready for CO2, you could try increasing your Excel dose slightly instead of cutting back. It's a balancing act, but some plants respond better to more carbon. Just keep an eye on them for signs of melting.
