well i just had like 3 fishes died in my tank and i dont know what the reason for its death. my water condition is fine. ive even tested it too and its safe, but the strange thing is i just did a water change like 3 days ago, for some reason the tank is still kind of murky. you can see it has a white cloud over the water. does that mean my water is not cycling properly? i have a 12 gallon nano cube
 
you say readings are fine then ask if its cycleing.If you know readings you would know if it was cycling.
What are you testing for?
How old is the tank?
 
the tank is about 2 months old but the first time i changed the water for my tank after a day the water is all clear. but 2 days ago was the second time ive changed my water, after 2 days the water is not clear, you can see a white mist in the water and im not sure what that is?
 
that white mist in the water is calcium, you should mix your water well with a heater and a power head and let it set for 3 days for the water to stabilize, and slowly drip the water into the tank, for such a small tank any sudden change in water parameters will cause a shock in the aquarium, some fish will not tolerate sudden changes in PH or water temp and they will go into shock, cushion and patience are the key to success in keeping these delicate animals.
 
so the white mist is the calcium, i see. cause i just added some calcium for the first time in my tank and i didnt know how it should look like, and my corals are actin funny too, i thought they were dying. but i got another question for yall what type of corals would u recommend for my small tank? right now i have a blastomussa wellsi, euphyllia divisa, and a duncan.
 
I would wait a couple of months before adding any more corals. Let the tank settle. Did you use RO/DI water or tap water for the change. How much did you change?
What are your params - particularly calcium. You said that your levels were fine so I am not sure why you added more calcium. Tell us Alk, Calcium, Nitrates, Ammonia Temp and salinity. It will help in establishing the cause of your problems.
Also - what 3 fish were they?

3 fish in a newly setup 12 gallon sounds like a lot of bio load. What kind were they and did you add all 3 fish at the same time?
 
well when i say my params were good i just meant the ammonia and nitrate i didnt know i need to add calcium and alk. the place where i bought the corals and fishes said i dont need it. they were like i just need to give it some light. but i went to the same place and another worker told me i needed calcium so he recommended me buying BIO IONIC 1 & 2. Well the 3 fishes that died were a clown, and 2 damsels. i used tap water for the change
 
Lack of or slight excess calcium won't kill your fish but using tap water could. That is the most likely cause of your problems. Only us RO/DI water.
