I'm pretty sure that my question has been asked in this group before; however, I am a noob to platned tanks. Do dirted tanks run out of nutrients? I want to dirt my tank with MGOCPM. I did some research on Google and I keep getting mixed information. Some people say that dirt runs out of nutrients, and others say it wont run out because the fish poop and other waste mater will keep it mineralized. I was wondering, what are other alternatives to MGOCPM?
