Tank Crash
So this is on my 5X2X2 system thats been up and running for almost 6 months now, all was well running with 6 fish and heaps of corals until i went out and bought 3 tangs including a kole tang labelled "needs TLC", a foxface and 6 chromis (all in one day), all was well for about a week after the purchase. The first to die was the kole tang which was looking very skinny, then another week later the foxface died, then the blue tang, then a few chromis, some hard corals, then the blue tang, then a few more chromis,, more corals, you get the picture. The strange thing is that it wasnt a "tank crash" in the way of all of the fish dying at once, but more random death over time, also fish that were previous inhabitants started dying so it wasnt just a batch of "dud" fish from the store.
Ive had the water tested at home and at the LFS and all levels are good (i dont have the exact parameters), so i have basically no indication of what is killing my fish and corals. lately ive been thinking the crash is over as i havent lost a fish for a few weeks and the corals are looking better (except my zoas which are all closed) but today i woke up to find my Yellow Tang floating on the surface and now unfortunately its on its way out.
The only other thing worth mentioning is that there has been heaps of cyanobacteria lately so i have purchased a phosphate reactor, however i doubt a high phosphate level is the cause of all the death.
