Thanks for the advice. I added live rock and a damsel 2-3 days ago to help cycle the tank. The water was clear. My ammonia levels were .50-1.0 because of the city water. I added ammo lock. This morning I turned on my tank, noticed the water was cloudy, my fish had died (*sniff*) and I have these light brownish worms with many little legs in my sand and on some of the live rocks, I believe they are called "Bristol worms", I haven't done research yet. I tested my ammonia and it spiked to 2.0, I added more ammo-lock (it says add every 2 days- and after 7 days if still present, do a water change)...
Here are my questions/concerns:
1) Are those worms harmful? I haven't seen them before adding liverock, so I am assuming they came with it. What should I do? I don't want them to multiply and over take my tank.
2) Is my ammonia supposed to spike because of the cycling process? I thought the liverock would have brought it down.
3) Can I use my freshwater master test kit to test saltwater? The Nitrite test says its both for salt and fresh. My ammonia test says freshwater, but my local fishstore guy said I could use the freshwater ammonia test kit to test my saltwater.
Any advice/help is greatly appreciated!
