Hello, I live in Australia.
4 days ago I bought myself a large 120 liter fish tank set up for saltwater fish.
The tank has a below gravel filter system and a thermostat, the temperature varies from 24 degrees to 26 degrees, which is what is recommended. The water was added with the correct amount of salt given to me by the aquarium who sold me the set up. The first day I added the water, salt, get the temperatures to the right temp and then added about 3 or 4 small pieces of live rock.
On the second day I took some water to the aquarium for them to sample, and they said the water was perfect and was cycling well. I bought and added another 5 or so large pieces of live rock, and placed them in the tank. The water seemed extremely clear and seemed to be doing very well.
The 3rd day I went in to get the water sampled and again, it was doing very well. i added 4 more pieces of live rock to finish the tank off
After adding the live rock I watched the tank for a little while and managed to see alot of little creepy crawly's get about the tank.
This morning when I got up the tank looked rather cloudy, but I was late for work so I didn't get much of a chance to look at it.
When I got home I notices some white cloudy stuff growing on the surface of the water, and a lot of the creepy crawly's looked lifeless.
I checked some of them, and it appears the miniature life is dying, I have removed 2 dead crabs and a dead snail so far.
I'm extremely worried, as I have done everything perfectly by the book, yet it seems my tank is dying.
Unfortunately I won't be able to get the water tested until Tuesday, should I be concerned or is this simply part of the cycle which gets the tank going?
