ok sounds good sooooo.... for next time i try to cycle my tank how longs should you wait? or do you need to test the water for ammonia?
tank "cycling" is actually a process where two different species of nitrifying bacteria colonize your tank.
The first species converts highly toxic Ammonia NH3 (NH4 depending on pH) into nitrIte (NO2). During this period you will show high ammonia levels in water tests, but slowly you should see increasing amounts of nitrIte. At this point in the cycle you shouldn't see any nitrAtes (NO3).
The second species of bacteria colonizes the tank in response to increasing levels of nitrIte (NO2). NO2 is also highly toxic and dangerous to your fish. This bacteria converts NO2 --> NO3. NitrAtes are toxic, but less so, your fish can tolerate much more NO3 than the other nitrogenous wastes. The best ways to remove NO3 from the tank, is to change the water frequently and to plant live plants in the aquarium. Live plants will use the NO3 as fertilizer.
Given the time it takes for bacteria to reproduce and establish sufficient populations to handle the nitrogenous wastes being produced by your fish, it is generally recommended that for a new tank you allow 30-45 days for the cycle to complete. If you have a good test kit like the API master kits, you can do weekly water changes until your tank parameters read as this:
NH3(4):0, NO2: 0, NO3: any nitrates indicate the cycle is complete, but for future reference it's best to maintain nitrates < 40ppm with 5-10ppm being optimal.
It's also recommended that you do this before you put fish in the tank. There are fishless methods, and methods that use fish, but generally a small population of somewhat disposable fish are used for the cycling process rather than the fish you plan to stock the tank with.
Any questions?
