What causes cloudy water in an aquarium and how can I get rid of it?
Answer: Cloudy water can be from many causes -- but usually it is from particles floating in the water requiring mechanical filtration. Or, it is from free-swimming white bacteria that come in to the aquarium through air contact or from living or dead organic materials in the aquarium. These bacteria are eating organic matter in the aquarium and rapidly reproduce.The bacteria population makes the water cloudy white. The bacteria can be killed by using an antibiotic that kills gram positive bacteria, such as erythromycinand can be removed by effective filtration. But you will still need to find the cause for having the bacteria and getting rid of it. The mechanical filtration can be aided by good quality activated carbon in the filter and from surface charged ceramic filter materials, such as Kordon's Bio Mech. Cloudy water often happens in new aquarium and pond start ups, because excess organics may be present in the water. A good practice is to be sure there is plenty of aeration from the start so that the fish receive ample oxygen. Bacterial blooms in the water consume a lot of oxygen and can deprive other aquatic life including fishes of the oxygen they need to survive.
Your Kordon AmQuel product says that a test kit using nessler reagents will register false ammonia test-kit readings when AmQuel is used to condition the water. And that instead a salycilate test kit should be used. How do I tell whether my test kit is nessler or salicylate when it doesn't say which it is on the box or in the instructions?
Answer: If the color chart for the ammonia test kit is in shades of amber it is a nessler test kit. If the color chart reads shades of yellow to green and may also read into shades of blue, then it is a salicylate test kit which is the one to use with Kordon's AmQuel.
For your information the salicylate test kit is the preferred kit for aquarium and pond keeping because it reads the low end of the range 0-1.0 approx. ppm (mgL). Even a small amount of ammonia less than 1.0 is toxic to aquarium and pond fishes. It is very important to read this low range. The nesslers kit reads in a range up to 9 or 10 ppm (mgL). It was originally developed for live sea food, such as lobsters, crab and shrimp, and mollusks, for which readings of several and more ppm (mgL) of ammonia are important in their survival.
Does Kordon's NovAqua contain bacteria that remove nitrate from the water ?
Answer: NovAqua does not contain any bacteria and does not remove nitrogen compounds such as nitrate.
Does NovAqua remove chloramines from the water?
Answer: First, an explanation about chloramines. Municipal and other water suppliers need to kill bacteria and viruses in their water supplies. This is especially so in municipal waters systems that are older and have corroded piping systems.These older systems provide many nooks and crannies in which harmful bacteria and viruses congregate. One way to kill these potential pathogens is by adding toxic chemicals to the water that kill bacteria and viruses but are safe for humans to drink. One group of chemicals used is the chloramines, which are made up of chlorine and ammonia. These combine together to provide a compound more toxic than if used separately. Chloramines are lethal to fishes and other aquatic life. Now for the answer to the question: NovAqua breaks the bond between chlorine and ammonia, keeping them separate in the water and thereby much less toxic to fishes and aquatic life than when the chemicals were joined together. NovAqua then removes the chlorine instantly, leaving the ammonia as a less toxic chemical in the water. Ammonia needs to be removed from the water by Kordon's AmQuel, which eradicates it within several minutes, or it needs to be removed by aquatic bacteria over days or longer, consuming the ammonia as part of the nitrogen cycle.
There is a great difference in strength and efficacy between the various treatments for aquarium fish on the market. All Kordon treatments are full strength and professional grade. Therefore, they should not be overdosed unless you know what you are doing. There are two general groups of treatments for diseases of aquarium fish - the antibiotics for bacterial infections for which it is essential to reach a threshold of treatment, and the chemicals for treating protozoans and multicellular organisms. The chemicals themselves can be toxic to some fishes and many aquatic invertebrates, particularly if over treated or the fishes to be treated are in poor physical shape.
Answer: The only function that the two products share is their ability remove chlorine from the water. Otherwise they are quite different, and each performs a different set of tasks very important in setting up and maintaining aquariums and ponds.
Is it all right to use two or more medications at the same time in treating an aquarium or pond?
Answer: No. The use of two or more medications at the same time is extremely stressful or potentially lethal to many fishes. It is often true that when fish are ill, they can have several different kinds of infections. For example, a primary infection of one pathogen can weaken the resistance of the fish to other pathogens. Even so, it is best to determine what is the primary infection and treat it first. It is possible that the fish, after overcoming the first infection, has also built up a resistance to other infections, and returns to being healthy. If not, after the first infection is resolved, then use a medication for the next most important infection, and so on until the fish is healthy again. The quality of water conditions and environment is an essential factor in the fish overcoming diseases. Be sure that all has been done to maintain optimum conditions in this regard. When fish become sick, they often refuse to feed. Therefore, be sure not to overfeed, which will rapidly degrade water conditions. Special effort should be made to ensure that the food offered is appropriate to the fishes diet and of the best quality available. . Whenever possible, use a "hospital tank" to treat sick fishes until they are fully recovered and will not pass on pathogens to other fish. This recommendation is all too often ignored, causing serious problems in community aquariums and ponds.
