the cause might be a sick fish, a dirty tank, or over feeding.

How do foam nozzles work?

Foam nozzles work by mixing water and a foaming agent under high pressure to produce foam. The foaming agent creates bubbles in the water stream, which expands the volume of the foam. This foam is then used for firefighting or cleaning, as it is more effective at smothering fires or clinging to surfaces.


What causes fish pond water to appear soapy?

White foam in a fish pond can be caused by organic residue gathering on the surface. This can be from fish waste or plant matter.


What are the elements of the foam tetrahedron?

The foam tetrahedron consists of four equilateral triangles connected along their sides, forming a pyramid-like shape with a triangular base and three triangular faces. Each face of the tetrahedron is an equilateral triangle, and the edges of the foam tetrahedron are all of equal length.

What foam is?

The most general definition of foam is a substance that is formed by trapping many gas bubbles in a liquid or solid. It can also refer to anything that is analogous to such a phenomenon, such as quantum foam. Often the term is used in reference to polyurethane foam (foam rubber), XPS foam, Styrofoam or some other manufactured foam. It can be considered a type of colloid.(Copy from Wikipedia:Foam)To create a foam, you need to start with a liquid viscous enough to hold some shape. Water alone will not do this. Try taking room-temperature egg whites and whisk them in a large bowl. Do this vigorously until you produce... (ta daa!) foam.


What are the conditions needed to produce foam?

In order to produce foam, several things are required. First, the surface area needs to be increased. Soap bubbles are a type of foam, for instance. The surface area is increased by applying force. Next, certain reactive chemicals are required. In the case of soap bubbles, soap is required. There are many different types of foam, such as styrofoam, all requiring different levels of force and substances. Sea foam is another type of foam.


Which is the gas that helps to make foam that firefighters use?

Air is the gas most commonly used to create the foam that firefighters use. Most commonly, the foam is generated by adding a small amount (1%-5%) of foaming agent into the water flow coming from the fire engine. This is done by either injecting it into the water stream with a small metering pump, or with a foam eductor which draws the foam into the water stream using a venturi. A foam play pipe, or Foam nozzle is used on the end of the water line which is designed to draw air into the stream of water, and creates the foam. More recently air compressors (CAFS - Compressed Air Foam System) are being added to some newer fire apparatus which injects air directly into the water stream. This allows for even less water to be used in firefighting, and produces a more consistant foam.


Are soft drinks foam?

Soft drinks do not contain foam as an ingredient. However, when opened or poured, some carbonated soft drinks can produce foam due to the release of carbon dioxide gas.

How can you create foam?

Foam is essentially a mass of bubbles. Bubbles are pockets of air trapped by (usually) a liquid, held together by a phenomenon known as surface tension. To create a foam, you need to start with a liquid viscous enough to hold some shape. Water alone will not do this. Try taking room-temperature egg whites and whisk them in a large bowl. Do this vigorously until you produce... (ta daa!) foam.
