Anaerobic Sand Please Help
Hello, I have bought most of the things for the 120-gallon tank I will be setting up. I will be having a 1.5" layer of organic dirt and then areas from 1" to 6" of pool filter sand. I have already bought the sand and the dirt and today I read that the sand could become anaerobic. Would that be a problem? The tank will be a low tech highly planted tank. I have read about the MTS but do not want them as they can reproduce out of control. Please let me know if there is a problem and if there is a solution to it. Thank you very much.
