Feb 28, 2013 - Cycle with fish can successfully complete the aquarium nitrogen cycle too if it is done correctly. It is also known as the fish-in cycle.
25. *How can I keep my bio-filter healthy down the road? The great thing about building a large bio-filter with fishless cycling is that it is a self-sustaining system that requires virtually no further work from you. The only things to keep in mind are to never throw away old filters until they are falling apart, and always seed a new filter before you throw the old one out. Also avoid doing heavy vacuuming of the substrate (floor of the aquarium). While most of your bacteria do live in the filter, plenty of it is also in the substrate. I recommend vacuuming only small sections of the gravel at a time. Last thing, if you are doing a large pwc, don’t take a lunch break in the middle of it. If you leave the tank walls without water for too long, the bacteria on them can dry out and die.
Nitrate is the end product of the nitrogen cycle. The simplest way to remove nitrates is through regular water changes. For the most part nitrate is not harmful to fish unless in enormous quantities and for prolonged periods of time, and even then it is only some types of fish are at risk. You will most likely not run into this problem in a regular home aquarium. Nitrates can actually be beneficial if you have live plants, as it is a nutrient for them. Tanks without live plants to utilize this nutrient however, can get excess algae growth. This holds true for both freshwater and saltwater fish only aquariums, but not for the reef aquarium. Nitrates are usually strictly controlled in the reef aquarium because they can cause undesireable algae growth.
Cycling An Aquarium With Fish Food

The process known as cycling is a way of cultivating necessary bacteria in a new aquarium. The bacteria are necessary to decompose the waste products produced by fish and other inhabitants in the aquarium. An aquarium will always need a combination of suitable bacteria cultures and frequent water changes to stay clean and provide the fish with a good environment. If you add fish to an improperly cycled aquarium they can quickly fall ill or even die, since their waste products will pollute the water. Some fish are more tolerant to moderate levels of soluble waste than others, but no fish will appreciate an aquarium with high levels of these toxic compounds.I would encourage all fish keepers to gain an understanding of the nitrogen cycle as this will help you understand exactly what is going on inside your tank and how you can deal with water quality problems should they arise.The simple answer is yes, an aquarium must be cycled properly before you can safely add your fish. It doesn't matter whether the tank is 15 gallons or 500 gallons, it's still got to be cycled. If you were to simply fill your tank with water and then add all your fish at once then there would be such a massive buildup of ammonia, the chances are your fish would be dead within a few days.Traditionally, there are two ways to cycle a fish tank. Both methods will involve introducing ammonia into the tank which will be the food the bacteria need to survive. The most common method of cycling an aquarium is to use small community fish that produce the ammonia themselves. A kinder, more acceptable way to cycle a fish tank is to use a method called the "fishless" cycle. This also involves adding ammonia to the aquarium, but as a name suggests you do not use live fish. In this article, we are going to use fish as it's probably easier for a beginner to undertake, and we wouldn't be happy with youngsters handling pure ammonia as it can be dangerous. If you would prefer not to use live fish then read this article on how to carry out a fishless cycle.We would recommend that you use small community fish like the Barb. The Tiger and Cherry Barb are absolutely ideal as they are quite a hardy species of freshwater fish and unlike some more sensitive species, won't turn belly up as soon as they are exposed to ammonia. If you are cycling a very small tank less than 20 gallons then you are probably better off using much smaller fish like guppies or neon tetra. Your fish store should be able to give you advice based on what fish they sell.It's important not to add too many fish as this will create a large ammonia spike very quickly which will probably just kill the fish within a few days. For a 55 gallon tank, 10 barbs would be appropriate. For a 75 gallon tank, you could go up to 15, for 100 gallons plus, you're looking around 20 upwards.It's become quite popular to kick start the cycling process by seeding your new aquarium with biological media that already contains live nitrifying bacteria.
