Woke up this morning and all the fish are dead. The bristle worms are still out and moving slowly, I don't know if they will make it or not. All was well last night when I went to bed. I did a water change yesterday afternoon, so I'm assuming it somehow ties in.
Background: 36 gallon bow front tank, fish only with live rock, tank has been set up 3+ yrs and was moved (sand, rock, water, and fish) from 55 gallon set up that was set up in 2009. Inhabitants: 2 damsels, 1 clown, crabs, bristle worms, apstasia (sp?). Water top offs every 3-5 weeks, water changes (1/4 to 1/3 of tank) every 6-10 weeks. I use tap (soft tap water locally) and treat with stress coat marine, then add instant ocean sea salt until at ~1.023 specific gravity (aiming for that in the tank, obviously may need lower sp. grav. if there has been a lot of evaporation), add aqua vitro eight.four. Let it sit, then add to tank. If it is a water change I add trace minerals, and aqua vitro calcium, ions, and fuel. Hang on back filter and heater set at 80-82. It does have the pretty red hard stuff on the rocks and back of tank. The rocks also have that thick green bristly stuff growing on it.
The clownfish in the tank I've had since 2009. She's been sitting on the rocks a lot more recently, but doing okay and getting to the food okay. The tank was getting a little more green algae to it, so this change I changed out closer to 1/2 tank. I also added top fin bacteria supplement. I've never added it to the salt tanks before, but it is marked for salt water tanks. Is this what killed everything?
I also topped off the 55 gallon but didn't add supplements. All fish are fine in that tank.
The temp was a little low in the 36 gallon tank this morning (78), which it has gotten down to before on cold days without any dead fish. I checked ammonia (between 0.0 and 0.5), pH (8.0), the nitrates and nitrates were high (not normal!), and the water read as really hard (this is what they normally read in the tank).
HELP!
I don't want to put anything in the tank until I know what caused the problem.
