On 01/08/2005 I started the setup of this aquarium. After going through a soft corals aquarium and another more mixed one, I decided that this time my aquarium would be mainly of SPS corals. My entire lighting has been changed and replaced by T5 light tubes (2 canopies 1.20 T5 ATI 4x56W + 2 canopies of 90 T5 ATI 4x36W). Until present this kind of lighting remains in my system, eventhough I've changed on a regular basis the light tubes (every 6 months), and I'm satisfied with this kind of lighting, both on the level of growth rate and coloration.

This system has 150 Kg of live rock and 10 cm of sand bed. The sand bed is a mix of several granulometries, being mainly CaribSea.

My name is Julio Macieira and I am the administrator of a marine aquariums forum in Portugal (www.reefforum.net) which has been serving me for several years to learn and share knowledge with Portuguese speaking aquarists.

I am very honored for the fact that Advanced Aquarist has chosen this time my aquarium.

I do not know how to speak in English, but with the help of a friend, I will try to answer you all, about any doubt that you may wish to place concerning my tank.

Thank you,
Julio Macieira
