Copper is routinely used in small ponds to control algae and treat certain fish diseases, but there's a fine line between the medicinal dose and the toxic dose. Copper is also toxic to snails and zooplankton (a.k.a. fish food), so your fish might need more supplemental feeding if there's copper in the water. The toxic component is soluble copper ions -- if the copper is bound up in chemical complexes, its toxicity is much lower. Some of the following measures may help to prevent copper poisoning:
1) To minimize the amount of copper that leaches into the water, your water should have high alkalinity, low acidity, and low chlorine. (Alkalinity is different from hardness or pH.) If your water is acidic or has low alkalinity you may need to add corrective chemicals, and you should use a chlorine neutralizer if you're filling the pond with chlorinated tap water.
2) Certain pond weeds -- Elodea and Centella -- absorb copper (this is called "phytoremediation") so growing them in your pond can help to prevent copper from building up if it does leach from the fountain. Remove older and dying bits periodically to make room for new growth.
3) Decomposing organic debris also absorbs copper. Normally people try to reduce the amount of organic debris, as too much of it can cause other pond problems. If you do leave some in for copper absorbtion, you should periodically clean it out and replace it.
4) Activated carbon absorbs copper, so incorporating an activated carbon filter into your recirculating system can help to prevent it from building up.
5) Measure copper periodically, and do a partial water change if the concentration gets too high.
It is both. The plural form is the same as the singular. This is generally true of the word 'fish' on its own or used as a suffix. I don't think 'fishes' as a plural is incorrect, but it isn't commonly used.

Both Indoor and outdoor fountains for wall mounting are usually constructed of marble, glass, slate, copper and a light weight resin or some combination of those materials. There are generally no screws or glues used to hold the pieces together. The stone is generally cut in a manner to fit together naturally with the rest of the pieces. The reason is that water would loosen the hold of many glues and it is very difficult to drill into stone without cracking it. The metal is bent to the desired shape through the use of machines and the glass is cut and molded to the correct size and shape. The wall fountain is set up with a pump at the bottom that cycles water up from the base or pond through a tube. The water then runs back down the indoor our outdoor fountain and collects again in the pool. Most fountains are electrically powered, but some use solar power. The copper used in wall fountains is burned to give it a unique and interesting coloration. This process is called teening. After the teening process the copper is powder coated to prevent it from turning green when it ages. Many pictures of wall fountains can be found at www.watergifts.com if a picture image would help you visualize a constructed wall fountain. The last step of the wall fountain creation process is hanging the wall fountain on the wall. A wall fountain can be hung by first attaching a piece of metal to the wall and then attaching the wall fountain to the metal. A video of the fountain hanging process can be viewed by clicking on the word fountain or going to http://www.wall2wallfountains.com/wall-fountain-installation.html
Ceiling fans typically use copper wiring for their electrical components. The amount of copper used in a ceiling fan can vary depending on the size and design of the fan, but it is typically a few pounds.

The ratio of the height of a fountain to the width of the pool below typically depends on the specific design and aesthetics of the fountain. Commonly, a ratio of 1:2 or 1:3 is used, meaning the height is one to three times the width of the pool, but these proportions can vary significantly based on the intended visual impact and the overall landscape design. To determine an exact ratio, one would need specific measurements of both the fountain and the pool.
The Trevi Fountain is made out of cement, rock and marble.
A pond filter is a device used for clearing a pond of micro-organisms. It is a must have if your pond has fish and they are having problems.
"Fountain pen liquid" is typically referred to as "fountain pen ink." It is a liquid dye or pigment used for writing with fountain pens. Fountain pen inks come in a wide range of colors and properties to suit different needs and preferences of fountain pen users.
The fantail goldfish is a good choice for beginners since they are very hardy and due to the fact that Fantail goldfish can be kept in temperatures close to the freezing point. Fantail goldfish are also an ideal choice if you want to keep some type of fancy goldfish in garden ponds due to the earlier mentioned reasons. Fantail Goldfish are recognized by their medium sized double/split tail fins. You can judge the breeding quality of a Fantail goldfish by looking at how far their fins are split. The tailfin of a high quality Fantail goldfish is almost completely split down to the root. You can find Fantail goldfish in a number of different coloration and with metallic, matt scale or nacreous types. Fantail goldfish doesn't grow as large as many other gold fish types and seldom reach a size of more then 16 cm / 6 inches which is small in comparison with other goldfish types such as comets goldfish that can reach over twice that length. They are best kept in cold water and a fantail goldfish aquarium tank or garden pond should be decorated with open areas for the fish to swim on as well as heavily planted areas. The bottom should be covered with a large grained substrate if you want to give any eggs that might be laid a small chance to survive with their parents. (Which is better then no chance) The fact that Fantail goldfish wants to be kept in cold water narrows down the number of (in the aquarium trade commonly available) plants that are suitable to be used in an aquarium with Fantail Goldfish. Pond plants and aquatic plants found in garden centres are often better choices. There is however a number of commonly available plants that are suitable to be kept in an aquarium tank with Fantail goldfish such as Crinum, Elodea (Egeria) and Anubias species. Java moss is another suitable plant to be used that also help give fry a chance to survive in your garden pond without extra help. Fantail goldfish should never be kept alone and always in groups. Fantail Goldfish accept most food sources and can without problem be kept on a diet of flake food and pellets as long as you make sure that the food you use contains vegetables. It is important to adjust the amount of food given to the temperature in the aquarium/pond at any given time. Fantail Goldfish is one of the easiest of the fancy goldfishes to breed. Make sure that you keep your fish well feed on a varied diet to get them in spawning condition. You will also need to lower the temperature in the pond or aquarium for a period of time to simulate seasons to get them to breed. Once the fishes have been kept in colder water for about a month or so you should slowly begin to raise the temperature and this process will trigger well feed, mature Fantail goldfish to spawn. You will have to protect the egg and fry from the parents or the parents will eat them if they get the chance. Some fry might survive and grow up in a well planted pond or aquarium. Large balls of java moss increase the chances for the young Fantail goldfish to avoid being eaten by other larger goldfish. Fantail goldfish can in other aspects be treated as the regular goldfish and we recommend that you read our articles about how to care for regular goldfish if this short article didn't answer your questions about Fantail goldfish and how to care for them.
Yes it/they can. Care should be taken to let the temperature of the water the fish is/are in slowly equalise with the water in the pond before releasing the fish otherwise it/they may die from temperature shock. I used to place a bucket containing the fish in its/their original water beside the pond and slowly replace a cupfull of water at a time over about 30 mins or so before releasing the fish into its new home.
