I currently have:
Aqua one 580 (35 gal tank)
2 T5s 15 watts each
Dymax cooling fan
i started my nano reef last june 2011. I cycled my tank for 6 weeks using uv filtered water sold from DLDB with sands and rocks all bought in carti. i have 4 fishes, 1 velvet damsel, 1 percula, 1 pink spotted goby and 1 mandarin. they are all healthy and fat fishes. Now, i added my first elegance coral. It was healthy for a week however, it died after. i tried another coral but sadly the result was the same. my water temp is 28 degs my water salinity is within the green zone of the hydrometer. i dont have a skimmer or a sump. and i also put drinking water every water loss. are these the reasons why my corals are dying? i follow the coral requirements like placement and water flow in live aquaria. thanks and advance merry xmas reefers!
