Hydrogen Sulfide in Deep Sand Bed
Hello! I have very fine sand in my freshwater aquarium - about 2-3 inches deep and I have a large fish that frequently burrows in the sand and disturbs it regularly. I had someone in another forum state that at some point hydrogen sulfide built up in the sand will kill my fish (guy was jerk but brought up a potentially serious issue). I can’t seem to find information on a how to prevent this from being an issue and it seems most people aren’t even sure this is a thing. Is this something I should worry about or be addressing in my tank? The most common solution is to not disturb the substrate - but what if I have a fish that digs deep all the time? Thank you for your help!
