Bought a used 65 Gallon reef tank
filteration: built-in overflow with a prefilter
20 gallon sump w/skimmer and refug
about 100 lbs of live rock
Tank has been running for several months
Ammonia, Nitrates and Nitrates are good
Problem is: My Chromis, Royal Grammas and Perculas keep dieing
My dragon Wrasse is fine and my Blue and Yellow Tang is fine.
I've gone thru 4 grammas and 9 perculas and over 20 Chromis
in the last 5 months. My other tank these fish are hardy but
when i buy some for my new tank they die within 1 to 2 weeks.
I was thinking maybe the old used crushed coral gravel is bad???
any Ideas...please guys I could use some help here
