Not bad considering the price and due to the fact that its covered for 12 months. You might want to enquire what flow rate the pump has (for that size it should be around 160gallons per hour or about 605 litres per hour) That can be swapped out later tho so its really not that big of a deal. Another question would be: is there a surface skimmer? You will need about 5.4 kg of sand and 4.5 kg of live rock (all of which can be purchased at a local fish store or online). The next question is whether or not you intend on putting coral in the tank or if it is going to be just fish. Regardless, you will need to do 20% water changes weekly. How much do you know about reef tanks? Do you know that you need to let a tank that size cycle for 1-4 weeks before you get any fish? Hope that helps, I'll be back a little later to answer any other questions. Oh and by the way :welcome to nanotank!!! The people here are awesome and you should find answers to any of your questions!
