Article: Since cycling a tank can easily take up to six or eight weeks, aquarium owners have long been looking for ways to shorten this process. One proven way to do this is to introduce bacteria from a tank that's already been cycled to the new tank. Since you don't have to wait for the bacteria in your tank to start growing naturally, your tank should cycle quicker than it otherwise would. One great source of bacteria is a tank's filter simply switch the filter media from the established tank to the new tank for a potential boost. Try to use filter media from a tank that's a similar size and has a similar amount of fish. Mis-matching your filters (like, for instance, using a filter from a tank with just a few fish in it to cycle a tank with a greater number of fish) can leave you with greater loads of ammonia than the bacteria are able to process right away. In the same way as filter media can allow you to "transplant" bacteria from an established tank to a new one, an established tank's substrate (the gravelly material at the bottom) can give you the same effect. Simply add a few scoops of substrate on top of the tank's existing substrate to get the benefit. Living plants (as opposed to fake plastic ones) typically speed up the nitrogen cycle, especially if they're introduced from a mature tank. Not only can plants carry beneficial bacteria (just like the substances above), but they also pull ammonia out of the water directly to use in a biological process called protein synthesis. Fast-growing plant varieties (like, for instance, Vallisneria and Hygrophila) tend to absorb the most ammonia. Floating plants also generally work well. One possible downside of using filter media or substrate from one tank to transfer beneficial bacteria to another is that it's also possible to unwittingly transfer other organisms. Many parasites, invertebrates, and assorted microorganisms can be transferred in this way, so be aware of this possibility in advance and never transfer material from a tank that's known to be contaminated with harmful organisms. Pests that can be transferred this way include snails, harmful algae, and parasites like ich and velvet. If you have a freshwater tank, adding a very small amount of salt can help your fish stay healthy when toxin levels are highest at the start of the cycling process. It does this by reducing the toxicity of nitrite, the intermediate chemical in the nitrate cycle. However, you'll want to use only 0.4 ounces per gallon of water at most any more can be very stressful for freshwater fish. Be sure to use certified aquarium salt table salt isn't formulated for your tank and may hurt your fish.
Question: What is a summary of what this article is about?
Add filter media from a mature tank. Add gravel from a mature tank. Have live plants in the aquarium. Beware of the risk of cross-contamination. Add small amounts of salt to freshwater tanks.

Mechanical watches need to be wound by hand periodically to ensure that the mechanical parts are being given enough kinetic energy to stay in motion and keep time accurately. Rolex technicians recommend winding their watches about 20 rotations once a month or so; if you're using a knock-off, the watch will probably lose time faster and you might need to wind it more frequently. To wind a Rolex-style watch, unscrew and release the crown until it is in the first position. Don't pull it out any further. The crown will then be ready to rotated, winding the watch's mechanical innards. Wind the crown stem until you start to feel resistance, then push the crown back into place and screw to secure it. Wind your watch every few days to keep it from losing time. As a rule, the more you wear your watch, the better time it keeps. The kinetic energy generated by wearing the watch on your wrist as it moves is transferred to the watch to keep the gears running. Make sure your watch is getting plenty of wear, or you may find that it is becoming less accurate. If you're not in the habit of wearing a watch, or are for some reason unable to, consider purchasing a watch-winder. Watch-winders are small devices that rotate your unworn watch continuously, mimicking natural motion. Leaving your watch on a watch-winder when you're not wearing it can prevent it from losing time as quickly. Watches, like cars and other mechanical appliances, require regular service. Take your Rolex replica to a watch specialist once or twice a year to have it inspected for mechanical flaws. A watch specialist can alter and replace springs, repair broken gears and keep the watch running like new. Watchmakers and specialists can usually identify tough to explain mechanical problems that might cause your watch to run poorly or stop altogether. Certain mechanical parts may wear out faster on replica models. It might be a good idea to get these parts replaced every so often. Replica Rolexes, while fine watches in their own right, are not made to quite the same specifications as the real thing, and as a result are more easily upset or damaged. Try not to expose your watch to excess moisture, and be careful about dropping it or allowing it to absorb impact. Even if these things don't break your watch outright, they may hinder the internal mechanics enough to render it unusable. Mechanical watches are also susceptible to changes in gravity, polar positioning and magnetism. They require greater care and upkeep than digital and satellite watches. If you're planning any sort of dirty or physical activity, it may be best to leave your Rolex replica behind. These watches were designed more for casual wear, and while they may be more capable of withstanding a moderate amount of punishment, it's better not to take chances.
