I just wanted to show my Elos 120 with an SM-100 ATS. The tank is 340 liters. The lights are DIY 280W LED + 2x54W t5 Actinic.
I have had the tank for 14 months. The ATS has been running since April, and for more than two months it's now the only N&P export. No skimmer, no filtersocks, no GFO, no GAC and no biopellets. I feed quite heavy with live phyto, reef pearls, D&D SPS food etc. I'm cleaning the media once a week, sometimes more often. I have a lot of SPS and at least three Gorgonias that are Azoox. I have a lot of different tubeworms/cocoworms and a couple of Tridacna clams. I have at least five different Zoas and a lot of different discosomas. All livning things seems to love the free floating food which is abundant.
One week of growth
After cleaning ATS-media
It's very bright (there's a window next to the tank) so it's hard to get a good picture of the whole tank. But this is it anyway. The rocks on the right are just added after a rescape due to fast growing corals.
