One more thing I wanted to ask about is.. Heating
Should I consider a under gravel or under tank heater to promote good water flow and bacteria growth in the substrate, as well as promote healthy root growth? I really would like to leave the tank up for awhile without a substrate overhaul.. but idk if 5 years is really the goal here. Thanks again for all the advice love all the tanks and people here ^.^ hope to hear from you guys soon!!
