The Ultra Zap PRO is supplied with a Quartz Sleeve. The tubes attached to the U.V Sterilizer need to be checked and replaced every 9-12 months. The quartz sleeve prevents water from coming into contact with the UV tube and so can be used in marine or salt water ponds and food production facilities.
Fish ponds, tanks, aquaponic systems, or hydroponic systems with green algae is unpleasant and makes it really hard to determine if your fish have diseases or are possibly injured. The green algae build up also runs the risk of starving the fish and plants of the required oxygen levels. However, when utilising algaecides you may run the risk of over-treatment and possible chemical build within your system. The inhabitants, fish and plants within your system are to a degree sensitive to such algaecides and may affect them.
What does the U.V Steriliser actually do?
The UV Steriliser is important to maintain a clear fish tank or pond throughout the year without adding chemicals that may affect the fish. The unit works by exposing the phototropic micro-organisms (free floating single cell algae) to a dose of U.V. radiation. The U.V. Steriliser effectively assists in destroying harmful pathogens and algae that may exist within your system especially during the warmer months of the year. A U.V. steriliser is used to control infections by stopping the spread of microorganisms from one fish/coral/invertebrate to another through the water. It is also utilised in pond applications, aquaponic and hydroponic systems in order to control free-floating algae.
When operated correctly, free-floating microorganisms will be killed by the UV light. Note that the organisms must be in the water that flows to the UV steriliser. The Ultra Zap U.V. Steriliser will have no effect on the on the inhabitants that exist within your fish tank, water tank, or fish pond. The UV light has no residual effect and will not kill organisms attached to fish.
Installing the U.V. Steriliser
The UV steriliser should be the last piece of equipment in the system before the water is returned to the pond. It should be preceded by the biological and mechanical filters, and any chemical filter or heat exchanger in the system. These units have 50mm inlets and outlets and we use normal 50mm PVC pipe to join them into our systems.
The correct size is about the only complicated part to the use of a sterilizer. For proper use, the UV sterilizer must be matched to the proper flow rate to ensure an efficient kill dose for the organisms you wish to eliminate.

Bio Balls are used for biological filtration. The main advantage of bio balls over other biological media is that the surfaces are impossible to clog up (when used with a pre-filter). The reason is simple: the gabs of space within a bio ball is large and anything that can clog it up would already have been filtered by the pre-filter (such as filter wool, sponge etc). This is the reason why water filtration should always pass through mechanical filtration (pre-filter) before biological filtration.

An aquarium with clear water is an attractive feature, which brings many hours of enjoyment and relaxation. A green, algae infested aquarium is unappealing to look at and makes it difficult to determine whether your fish and coral have disease or have injured themselves. Algae also poses a threat as it starves your fish of the essential oxygen they require.
An Ultra Zap UV unit will eradicate free floating algae and maintain a clear aquarium throughout the year. The UV works by exposing the photo tropic micro-organisms i.e.: free floating single celled algae to dose of UV radiation. This destroys and prevents the regrowth of the algae. Ultra Zap UV’s have no side effects on the inhabitants of your aquarium and its environment.
Control free floating single cell algae and sterilizes the aquarium water with no side effects to your fish, plants or coral.
How it works.
An Ultra Zap UV Sterilizer will maintain a clear aquarium throughout the year without the use of chemicals. The unit works by exposing the phototrophic micro-organisms (free floating single celled algae) to a dose of UV radiation. This destroys and prevents the regrowth of the phototropic micro-organisms.
Safe to use.
Ultra Zap UV units have no side effects on the inhabitants of your aquarium or environment. If algaecides are used, you have the risk of over-treatment and/or residual chemical build up in your aquarium. The inhabitants, fish and plants, of your aquarium are to some degree sensitive to algaecides. With the use of an Ultra Zap unit you stand no risk of this.
Choice of unit.
There are four units available, 8 Watt, 15 watt, 30 watt and 55 watt. The use of a quartz sleeve is recommended with the use of UV units in marine reef aquariums.
UV-C (315-400nm) is often referred to as germicidal wavelength, because of its ability to destroy micro-organisms. The tubes in all of our UV sterilisers emit a wide range of ultraviolet with its most significant part at a wavelength of 253.7nm, which has been found to be the most efficient for germicidal action.

Bead filters are closed (pressure) vessels filled with thousands of plastic beads. These beads are very close together and form a layer through which the water is forced by a pump. As a result, the dirt particles stick in the beads. If the filters are used for some time, the biofilm (the sticky layer) around the beads becomes thicker, so that finer and finer dirt is caught.
