Unexplained Deaths
First post so please excuse and rookie errors!
I have come back to reefing after an extended period off and have researched more but have come up with no answers to my problem.My tank is 250 litre with LED lighting live rock and protein skimmer on a sand base.
My problem is the fish in my tank all died. Full explanation:
1)Tank cycled for three months with live rock.
2) During this time (at about 6 weeks) my neighbour passed on some Zoos a staghorn type coral and a few corrilamorphs (Excuse spelling) that he was giving away. These have thrived and grown significantly since.
3) 2.5 weeks ago I populated the tank with 2x clowns and 1x blue tang (all small in size) over the next 2 weeks alll died. I replaced the tang but it also died.
Water parameters are as follows:
Ammonia 0
Nitrite 0
Nitrate 6.01
Salinity 1.026
temp 25.5
alkalinity 7.2
calcium 470
magnesium 1450
phosphate 0.08
All of these measurements have been stable for the last 6 weeks aprox. Even after the deaths.
I am confused as I thought anything that would kill off the fish esp. the hardy clowns would also sow/damage the zoos and coral. Any help would be much appreciated
