I have a 37 gal. tank, with 35lbe of live rock, and a uning a 400 skillter filter. I've had this tank for 6 months and untill and week ago all was great, then one of my clown fish died the the other the following day. Then 4 days later the damels i have in the tank died leaving me with no live fish out of 6. All test were good except nitrates were at 40. The fish all seemed to be fine till near death when there eyes became puffy and breathing picked up rapidly. What could this be, what should I do, how will I know when it will be safe to put other fish in the tank again. My emerald crab and tubro snails, and anemoie still seem to be doing fine. Any help would be grateful.
