fertilization for plants and charcoal in HoB filter
Ok please dont laugh kinda new to planted tanks had saltwater tanks for 25 years and decided to try my hand at freshwater planted tanks. I was told that any fertilizer you put in the water for the plants will be filtered out if you run Activated Carbon in your filter system, so my question is is there any truth to this?
thanks in advance
