Hi all, I have decided to come back after 4 years of leaving this wonderful hobby. I am going to set up a 3x2x2 rimless with sps and lps mixed reef. Did some research and still considering to get LED of t5. If i were to get t5, ATI will be my choice and no doubt about it. For LED I am considering between Mazarra S and Radion. Seen the Radion demo at Iwarna, I am impress. I was told 1set of Radion is able to cover the entire tank and it cost slightly more than 1k which is about the same
