chipping in my two cents..... currently have a nano tank with ios for abt 8 months. Definitely regret it to this day. Just waiting for a chance to upgrade soon. Main reason is the limited real estate. A nano tank definitely got me going in this hobby and i have learnt alot from it. But if you are anything like me, a few months down the road, confirm be itchin to upsize. The sunk cost for a nano tank isnt worth it Sent from Singapore Reef Club mobile app
