I just upgraded my tank to a 20 gallon and I used my quarantine tank to house the fish plants and wood while I was making the transition I’m planning on getting some more fish and my question is do I need to sterilize my quarantine tank before I get them or should it be fine? There is a bit of mulm and gunk in the tank from the plants and wood and I cleaned out the majority of it I just dont know if I need to sterilize it or not or would it not matter? Since I was just using it to temporarily house the things in my main tank.
