Hi guys. Need some opinions here. I need to leave a tank for a few weeks with no livestock at all in it but liverock and sand. Do you think it important to still run a skimmer? The water will still be circulating but lights will be off as there will no fish or corals that would need the lights.
So please answer the poll yes or no and give me your reason.
