Hello,
I need some help please with my two-year-old Bio Cube 29. It has always been relatively stable. I do regular partial water changes with Nutri-SeaWater. I use Seachem matrix carbon, Purigen, and Chemipure Elite in a media basket and have a protein skimmer. I have lots of live rock with copious amounts of coralline algae.
I had several soft corals, Kenya tree corals, mushroom corals, several polyp rocks, two feather dusters, a small coral banded shrimp, a red-legged hermit crab, a serpent star and five small reef fish. All were doing well and some of the corals were actually flourishing.
About a week ago the tree corals, which had always done very well, began to die, followed by the coral banded shrimp and then the feather dusters. The water turned slightly cloudy. I removed as much of the dead carcasses as possible, did a partial water change and changed out the filter media. A few days later, all the invertebrates in the tank, including my serpent star, began dying wholesale. The fish seemed unaffected. I checked for any kind of metallic poisoning, but couldn't find any possible source. I checked the water parameters: ammonia: 0.02; O2: 8.1; pH: 8.2; nitrate: 5; phosphate: 0.0; temp: 78-degrees F; specific gravity: 1.025.
The ammonia was slightly high due to the die-off, so I did another partial water change. The water is still slightly cloudy despite the new filter media. The rest of my corals are looking really bad and more have died. The fish still seem to be behaving normally and are apparently unaffected.
I am puzzled as to what is going on. Doesn't seem like anything is helping, the tank continues to die. The only changes prior to this happening was the addition of a small rock covered with mushroom corals and they were doing well. No equipment changes, medications added or lighting changes were made.
Any ideas?
Thanks,
Kerry
