I had a 6 X 2 X 2 marine system, I had all different types of hard coral and soft coral, flame angle, blue tang, achillies tang, prawns etc. I use to properage the hard coral and give them away.
I use to do every week a 80 liter water change.
But no more! I sold it for $1200 au. First person that saw the set up bought.
The reason for selling being that I had to get someone to come over and check on it every couple of days when away and check everthing was ok and feed the fish etc. It flooded the lounge room on several occasions due to power black outs that were not my fault. In all to much stress.
Saying that even my wife who had a love hate relationship with the tank say's it was the best marine tank she ever saw and we travel all through out Australia. Checking out Aquarium shops for that next piece.
But she will never let me get another one again
