I have been keeping planted tank now for about half a year and think of keeping discus with it.
Living in a tropical country I do not need a heater in my planted tank yet. But since I keep discus, heater is a must. But I read form a book that normal glass heater is not good as the substrate may turn anaerobic. Causing harmful product like hydrogen sulfide which can kill fish. And it advise to use substrate heater. Substrate heater is expensive, I don't think I can afford one.
Is there anyone that keep discus with just normal glass heater?
I need some advise in this.
