I can't seem to keep any fish long term. I have a 4ft 120g tank with a 125g basement sump. Roughly 190 gallons of water volume and aproximately 140lbs of live rock. The list of fish I have lost over the last year is as follows: 12 blue/green chromis, 3 bangai cardianls, 3 anthias, 1 gold bar cardinal, blue damsel, yellow corris wrasse. The only fish I had left 6 weeks ago are a kole tang, yellow tang, blue mandarin. I had 9 chromis, 1 bangai cardinal, 1 blue damsel, 3 anthias. After looking over the tank and testing the water parameters and also having the local fish store double check my results I decided to add more fish to the tank again. I added 9 chromis, 3 gold bar cardinals and a hector goby. That was a week ago. I have currently lost 3 chromis ( one jumped into the overflow and died in a sock filter overnight) and a goldbar cardinal. I checked all the parameters again. Nothing is out of whack. I feed well, twice a day alternating between small pellets, flakes, nori, mysis, and krill. The fish seem to do well at first then will start becoming anti social, stop eating then die. I don't see any signs of disease or trama to the dead fish. Any ideas?
here are the test results and for whats its worth, I've been tracking these two weeks (1 week prior to adding fish)
sg 1.025 steady
ph 7.85-8.04 over the two weeks
mg 1300-1400 over the two weeks
ca 560-600
kh 7-7.95dkh (was dosing and raising to 8.5ish but had a coral stress out so stopped dosing for 3 days until kh dropped back to 7.5dkh
No3 0.0
Po4 0.05-0.13
temp 77.9-79.9 doesn't have any major swings, less than 1 degree change over a 24 hour period
ammonia 0.0
