Hi,
This is my third reef tank, it has run for one years, but it takes me about six month to deal with the problem of hair algae(Bryopsis) from previous tank, after long time fighting and I almost restart the whole system, everything have go back to the normal track. Fortunately I have not lost many old SPS coral in this process, so I could rebuild this tank with many mature corals from old tank.

The right side of the tank, almost all the coral is come from old tank, some of them is over four years in my tanks.

On the left side it is mixed with old corals and new corals.
The lighting of the tank is 3 x 400W XM 10000K only, but now I am planning add some VHO and LED as the blue light supplement.
