Coloring up the plants
I have a 40 gallon breeder planted tank. The plants are doing well without algae issues. And the fish are doing great.
The problem is that I can't get some of the plants to color up red. They get 4wpg, pressurized co2, and they get regular ferts every other day except Friday. I do a 50% water change every Saturday.
Like I said, the plants are really growing nicely and they pearl a lot too.
What could be the problem? Maybe it's iron?
I appreciate any help that I can get.
