Ok Is your goal to cycle the tank? If so then I'd stop putting fish in there. Don't add any fish until it's cycled.
If you want to start over (which I suggest just incase it was some kind of disease) then I'd dump your tank out, clean it with REALLY hot water and vinegar (I wouldn't use bleach. It takes WAAAAAAAAAAAAAY too long to rinse. I mean like over 50 rinses too long. I wouldn't try it. Vinegar is an acid and will get any residue on the glass of and do so in a gentle non-toxic way. =]), wash all the decor and gravel in hot water and vinegar, rinse everything 2-3 times then start over.
Before you start cycling this time you'll need a test kit. The API Freshwater Master Test Kit is the one you want. =] It's a liquid test kit so it should last you AT LEAST a year and it gives you the most accurate results possible if you follow the directions exactly and clean the tubes well after each test.
When you start over you'll want to add an ammonia source such as raw fish, fish food, or pure
ammonia. And by pure ammonia I mean no other additives. ACE Hardware sells pure ammonia. It's their store-brand Janitorial Ammonia. Here's a link.
Pure ammonia is the most precise route but you have to be careful to feed the tank enough or else your cycle will crash. The Raw fish method works but you need to be careful to take the fish out before it molds./ after that you just let the water sit. Then with the fish food method you do the same thing as the ammonia method but there's a big chance that you'll get a major algae bloom because of the phosphates that can sometimes be found in fish food.
The cloudiness in your water that you were trying to get rid of was mostlikely the bacterial bloom that you wanted.
If you tank water get cloudy during he cycling process it's most likely the good bacteria booming. This is a good thing.
You'll want to refer to these links
as well as the cycling sticky
before you attempt to cycle again.
You could also fish-in cycle I guess but since you're out of fish any-way I'd just go ahead and cycle it before getting any more.
If you want to fish-in cycle though I'm pretty sure there's info in the cycling sticky about it. Basically if you're doing the fish-in method you make a lot of small water changes but never do a 100% change. eventually you'll get the ideal readings and your tank will be cycled.
Bacteria in a bottle is worthless btw. I wasted my money on it once and regret it.
Good luck with your cycling this time around. =]
