Cycling fish tank was foggy and now clear. Almost done?

you could test the water by throwing in some feeder fish that cost like 10 cents each. see how they do. if they live or die then you have your answer.

Using plain non-detergent ammonia is the best way to cycle the tank without fish.

I have a 72 gallon and added a teaspoon of ammonia per day. If you can get some used filter media from someone that has an active fish tank and wring it out & shake it in your tank, that'll help the cycle along. I had a test kit for ammonia, nitrites, and nitrates. Once the ammonia and nitrites have gone away (before adding the daily dose of ammonia) the tank should be safe for fish. At that point only your nitrates should be present, so you can do a partial water change to lower it (or get some live plants to help). You might only need 1/5 TEAspoon of ammonia per day to establish and feed the ammonia bacteria... Mine actually stabilized in about 3 weeks. I used filter media from my other tank too.

cycling tank takes 4 to 6 weeks especially with small tanks like yours. no,it's not finished cycling yet. you're still short 5 weeks and a day. i haven't experienced putting something dead when cycling a tank. chances are, it would be the wrong kind of bacteria that might flourish your tank. it'd be better if you put some live hardy types of fish like maybe wild guppies as you must take into account that it is the presence of ammonia that is necessary to allow for the growth of the nitrifying bacterias and any fish put in the water,will automatically produce ammonia. also if you can,you can float a few stems of anacharis or hornwort in your tank to hasten the cycling process if you will. much luck.

The only real way to tell is to wait for the test kit, but, if it's only been a week then my guess would be that no it isn't cycled. And with the shrimp method I'd leave em in until just before you add fish.
