Yellow,cloudy water

Question
I just bought a  new 27 gallon fish tank. And when I put all my fish in it they all died. But now the water is really yellow and very cloudy. I dont stand why either of them problems even happened. I need help !!!

Answer
there are many reasons why this is happening.
in a new aquarium your tank must be rid of chlorine with the water conditioner you find at your favorite pet store.
also the tank that you bought them with may carry some harmful bacteria so in the future fish them out with a net and put them in your tank.
yellow water is produced  by fish waist,new drift wood, or DOC (dissolved organic carbons) the best way to fix this is change the carbon in your filter and do a 25%water change every 3rd day.
when you first start off an aquarium research the fish your buying for temp,food,size,living conditions ect.
and bring your aquarium to the standards of the fish before you introduce them to your tank.
you might also want to buy water test for chlorine,nitrite,nitrates,ammonia,water pH,hardness.
do your homework to keep a healthy happy home for your fishy.
hope this answered your question!
