Although systemic treatment of a display aquarium is often necessary, when possible, treatment in a quarantine tank will avoid the above problem in the first place.
Please see this article for further information about medications: In a healthy Saltwater fish aquarium nitrates should be below 40 ppm.
In a healthy Marine Reef aquarium nitrates should be below 20 ppm or even less, many reef keepers aim for less than 10 ppm. In other words, the ammonia and nitrites have gone up then back down which can take from 10 to as long as 45 days depending on method tank size and temperature.
I will note that method one if done properly rarely results in an ammonia and nitrite spike, this is why it is my preferred method WHEN possible.
Regardless of method used, a product that can further aid in establishment of your bio filter is AAP Shieldex. This is NOT a cycling aid, rather it is a slime coat and water conditioner that also works extremely well as base for nitrifying bacteria to cling to.
One simply needs to squirt some of this product into their bio filter media and it will then make for a base for these bacteria to get a jump start in seeding further. AAP Shieldex Water Conditioner, Beneficial Bacteria Base Finally, before I jump into different cycling methods, I would like to note that testing your and keeping a journal of your water parameters during the cycling process as well later on, but not at as frequent of intervals is important in my opinion and will help you note subtle changes.
Reference for further information: Aquarium Chemistry  Seasoned Filter Media: My preferred cycling method is to transfer filter media. Sponges work well as Autotrophic nitrifying bacteria tend to cling to sponge media in high quantities and sponge media is easily transferred, although floss, ceramic media, volcanic rocketc.
To prevent this transfer of disease pathogens and parasites, only use a media source where no new fish have been added in 30 days, ALL water parameters are good, and if possible has UV Sterilization although not necessary. Unfortunately this filter itself would not be fully seasoned as it would have needed to be running in the established aquarium for weeks for this to happen, so starting a new aquarium with a filter not allowed to fully season will result in poor results in the new aquarium.
If fish are not added before days, I suggest adding a small amount of liquefied fish food to feed your growing bacterial colonies. I will also note that the days seems a bit vague, however this can vary due to temperature, amount of bacterial seed, and other factors, so I would not be overly concerned about the exact timing as I have added fish as soon as 2 days and as long as over a week with no problems.
In Marine tanks I still prefer to added aged media not essential, but still better along with lbs 2. This method added media will give you more instant bio bacterial colonies and this is method that is used by far the most by the professional aquarium maintenance community which needs faster more sure results for their clientsdespite the internet popularity of the next two cycling methods.
We used this method for our Aquarium Maintenance route for years and never lost a fish to Ammonia or nitrite poisoning, and disease transfer was minimal.
It should also be noted that when done properly, you will rarely see ammonia levels rise past. In this case, I would recommend one of the next two methods.
Further seasoned media cycling method tips An ammonia spike is not uncommon with the use of seasoned media for there to be an ammonia spike when more fish are added, often this spike may take a several days depending on the amount of fish added as well as the bio load that the seasoned media has grown to handle.
Generally this is not too much of a concern, but the use of Prime, cutting back on feeding, and definitely placing the addition of any other fish "on hold" until the nitrifying bacteria "catch up" with the new bio load are good practices.
As an example of what happens and this is NOT scientific, just an analogy: If say you added a sponge filter from a 20 gallon tank that is fully seeded to another 20 gallon tank that is brand new or restarted after bleaching. I should note that with the use of seasoned filter media, generally the nitrifying filter media will quickly colonize the rest of the tank, so waiting weeks to add more fish is rarely necessary at least I have never observed this in many trials using seasoned filter media.
Add drops per gallon pure ammonia so as to bring your ammonia level to ppm. Then repeat this a few times, each time waiting for the ammonia level to get back to "safe" before. Continue to add ammonia into the aquarium until the ammonia level goes to zero within hours after the ammonia is put in.
As well the nitrites should also come down and stay down at 0.The biggest environmental impact of disposables happens before you buy the product. The majority of a product’s impact—energy, resources, carbon emissions—come from sourcing the materials, manufacturing and transportation.
