Hi fellow reefers....
I'm new here but need some advise and opinions please. I'm confused with all my setup. It all happen when my sea apple went missing one day and died inside the LR. All the livestock went berserk and eventually died. I managed to save my lionfish, blue damsel and watchman goby but I lost 4 fishes. As for the corals and anemones I can't save them. I feel so devastated and almost give up the hobby. I have to do a major cleaning on the fish tank as well as the LR. Then started a new cycle again. The problem is after 3 weeks of cycling the water, I put in my corals in stages and eventually introduced my fish into the tank. However the corals closed up and my inverts started to dies off after the 2nd week. I tested the water parameters is ok but I'm still losing them. My calcium is about 440 mg/l and the temperature is at 25 degrees. Did 30% water change but it worsen the situation and finally lost my inverts & corals again. It was a heart pain to see the lost ( feeling guilty and horrible). Now I only have FOWLR and a dying tube anemone also died two hours ago. What went wrong when I'm still using the same setup to cycle the water?
FYI I have 4x2x2 tank, eheim cannister filter(pro II),overhead filter, Atman chiller, prizm and queen turbo skimmer, actinic & white light(55watt on each side), #0 substrate at 4" depth and 3kg LR. Please help and do explain it in a simple way as I'm new here
