How can i tell if my tank is cycled or not? I know that it is when all of the bad ammonias are out of the water and such but i dont have an ammonia test kit as of yet. I am cycling a 90 gallon using 6 longfin zebra danios. I took the filter media out of my pond, cleaned it in some water from my pond, ant put it in my 90 gallon tanks filter. I also took about 15 gallons of water and a PVC pipe i had in my pond to further help the cycling process. The danios are extremely active, and are eating extremely well on bloodworms. The tank has not gotten cloudy once. Now i know danios are very active and can tolerate a some very extreme water conditions, so i took a goldfish that was supposed to be a feeder out of my pond and put him in. He is also acting very active, picking through the sand looking for food, what he usually did in my pond. Now i plan on getting a test kit sometime this week when i have free time. But, can anyone tell me from the info ive given you if it is cycled or not? Oh, and its been about 2 1/2 weeks since i got the danios, about 3 weeks the water has been running in the tank.
Is my tank cycled?

it should be cycled when you test your water and get 0 ammonia, 0 nitrite, and a little nitrate like 10. good luck with the new tank
BTW: whats going in the tank?

I gaurantee your ammonia is at 0 but nitrites may still be high once that is 0 u are ready it usually takes 4 -6 weeks to cycle a tank

I agree that it usually takes 4-6 weeks to cycle a spankin new tank, but he used established filter media and water when he started it up. I did the same thing. I took a bio wheel, about 5 lbs of gravel, and 30g of water from my 55 and had an insta cycled 90g. Never had 1 NH3/4 or NO2 spike. I would guess that since the fish show no signs of stress and established media was used that his tank is fine. b/c if there was a No2 spike the fish would not be happy campers.
I have successfully "cycled" several tanks by just borrowing media from my own established tanks. I have never seen any ammonia or nitrites of any significant levels. Everytime I have slowly added stock to ease the bio load of the new tank......never a problem.
During these new start ups, I still tested the water....just never detected anything. Never lost a fish either.
