Hello, I've had a 125 gallon saltwater tank for about 8 years. I ran into this site yesterday when I was troubleshooting the cause of a cloudy tank. It's been so long since I have had any problems that I am very rusty at what to do. Anyway, as you may have guessed, what I discovered is very sad!
Corals are all but lost, fish are still okay, but I'm afraid that it is a matter of time since the tank is cycling. Most of the stuff in my tank has been around for about 4 years (since the last tragedy hit while I was out of town and as a result lost all my fish except "Lucky" who is still alive today). Anyway, this site is very helpful.
I suppose at this time I just need to wait out the bateria bloom with frequent water changes and hope for the best. Any other ideas? I lost an anenome about a week ago that I had just bought, which may have started the problem, but I didn't notice anything until after I did my regular water change on Saturday. I used Amquel (which I never do, but I ran out of Stresscoat) to condition the water. I have since thrown the bottle away. I don't know if it was bad or I already had something going on in the tank before that. I don't have an ammonia kit and seeing how it is Christmas can't run out and buy one, but nitrites are quite high right now.
