Get home from work today; we have a dead bangai cardinal; 2 dead firegobies; one dead pink seacucumber; and one dead foxface.
Nothing in the tank looks good. Tested the water; PH is high (8.6); nitrite's ok; nitrate's a little high (15-20); been higher in the past and no problems; calc is 400 and alk is normal. Salinity is good. Water temp is the same and normal.
The skimmer is working overtime like crazy though. I can't figure out what's wrong.
Any ideas?
