My girlfriend bought this tank. It is a very nice tank. She is now regretting the purchase however. She wishes she had an Auto Top Off (ATO) with it. We can add it but it won't be as clean as an ATO going into a sump in a stand. She added a protein skimmer that fit in the back chamber but this removes one of the filter socks. You could do hang on back but aesthetically it may not be to your liking. Without an ATO the water level changes and the skimmer does not run optimal. She spent $300.00 on an LED light that has an on and off with moon lights. Now she wishes she spent more for a light with a controller so she could setup a custom scheme where they come on at X time, gradually get to full power, and then build in less lighting throughout day for rest periods, and then go off at night without having to do a thing.
Overall it is a great tank but as you learn more about saltwater you may have wished you bought something else that can be customized more. I would do a lot of research on the differences between an AIO system and those that have built in over flows that go into a sump. If you are looking for a basic saltwater tank with fish and live rock this may be your ticket. If you are going to get into corals I would research the benefits you can gain by having a built in over flow that goes into a sump.
