my second loss

[medic_eva]

kay here are the parameters

salinity 1.025
calcium 660 (holy freaking high)
phsopahte 0.5
nitrate 5
carbonate (alkalinity) 100 (so it's about 5 points low)
ammonia 0.2-0.3 (i assume because of two dead animals in less then 2 days)
nitrite 0.1


any ideas? going to do a water change tomorrow, about 2.5g on my 25g tank. nothing else seems to be having problems in these parameters. no corals are closing up or anything. i dunno. i am at a complete loss of idea of what happend.
