I have a 55 gal
tank that I want to eventually be a reef tank. It been running about 6 months with 30lb of LR
from a previous tank with an additional 50lbs of base rock. A tomato clown a 3 stripe damsel and assorted hermits and snails make up the livestock.
PH 8.4. Kh
12. Salinity 1.025. 0 nitrate 0 nitrite
Berlin style sump with protein skimmer
So 3 days ago I add 3 green chromis, they all look fine after acclimation. This morning I wake up and my 3 stripe and 2 chromis are dead along with an emerald crab! Any help is appreciated, because my first feeling was to tear down the tank and start again. Thanks for looking.......John
