Filters, skimmer, pumps are all inclusive as are lights. Its a complete all in one setup. You may need to add a chiller for warmer Australian conditions and a pump for that. There is provision in the back for the pump.
I added an extra bit, a two little fishies phosphate reactor. Took a little bit of time to drill and cut the holes in the back but works well.
I also added a wavemaker to get a bit of different currents happening.
I would love for redsea to put out a replacement hood with LED lights installed rather than the T5's which need their tubes replaced every 6-9mths for full spectrum lighting.
In the end I am happy I only got a 3ft tank as I am using salt mix to do my wc and that stuff is expensive to buy. It is quite a small tank for corals and anemones to grow in and stretch out tho.
