What I have is a 29 gallon growout that is bare bottom. I wanted to add some plants into it so that my little flowerhorn spawn could run and hide from each other. I have a Broadleaf Anubia? attatched to some driftwood. Is it dying? Or is that just some algae growing on it...
Also is there a "best brand" for the liquid nutrient stuff? I don't want to lose it as I've invested a lot of time and effort to get it to attach to the driftwood
Dosing more broad spec fert blindly is worse than doing nothing. Most likely you are lacking in potassium, but without testing the levels, it will be impossible to say for sure.
