HELP! My 100 gallon fish cistern freshly go blurry?

On Monday I set up my 100 gallon freshwater tank.
On Tuesday I put 10 Danios and 1 freshwater red tiny crab.
On wednesday the water was really clear and dependable.
TODAY The water is blurry!! is is not perfectly clear anymore.

I just tested the hose down and it is fine.
should I return all the danios and the red crab and just cycle my tank for 2 weeks near no fish? I thought the danios are sopose to start up my tank and help with microbes and such?

why is it blurry today?
It cycles next to or without fish and part of that is an infusoria bloom, which is tiny little bugs munching on the fish food. They will die contained by a day or two and you will get an ammonia reading, then the germs convert that into nitrite followed by nitrate. Carry on this is supposed to happen.

I don't know who told you 100 gallon will cycle in two weeks, but whatever they be smoking was good stuff. More like 4-6 weeks and later gently increase the number of fish, two or three per week.
OMG, did you do any reading on the cycle at all ? That's whats supposed to happen, the fish create waste(ammonia) and after the good bacteria start to grow. The cloudiness you see is bacteria growing also call a bacterial bloom. It could take anywhere from days to weeks for it to fully establish and once it does the cloudiness will go away.

Also the freshwater crab wants a spot of land to get out on, its not fully aquatic and wont live long whether it has no place to get out of the water.

Also 10 danios is mode too many, take 5 back. \

Good Luck
Answers:    The cloudiness you see IS the bacteria. At the start of every cycle, there is a stage within which a "bacterial bloom" is present. It is when ammonia occurs and the population of bacteria explodes- but quickly dies down as ammonia is used and cannot support such a huge number of them.

Since the cycle is already started, newly let it run its course.
It is cloudy because it is going through a nitrogen cycle. With care, you should be able to hold your fish through this process. Here is a website with more information for you.
