30W UV STAINLESS STEEL STERILISER

Single cell algae’s forming green water are not just unpleasant to look at, but at the same time contribute to lowering the “kh” value which is so important to fish health, and to the nitrification process within the filter system. Algae’s also contribute towards lowering oxygen levels, whilst meanwhile increasing “ph” levels – both of which are not desirable. The use of Ultra Violet is the safest of international techniques for obtaining clear water, and unlike many chemicals detrimental effects of pollution or over-treatment are impossible. In addition general plant and pond life are unaffected with a UV.

HOW THEY WORK

The actions of ultra violet light onto single cell algae does not actually kill them, but converts the algae’s DNA structure to the point where they flocculate together, and thus form larger particles which will not so easily pass through the mechanical filter mediums. The amount of sunlight which the pond receives is the biggest of factors in the promotion of algaes, and for such reasons the selected size of a UV unit should take such environmental aspects into account (see UV Calculation Chart Below).

WHY BUY CLOVERLEAF

The Cloverleaf range of Ultraviolet Clarifiers have many unique design advantages that make them the finest and safest unit available on the market today. Only the Cloverleaf UV incorporates a highly efficient spiral water flow for maximum exposure, and the latest electronic technology is used to provide the unit with low power usage – combining a built in resettable fuse totally safe for outdoor use. The range of models (from 8 to 330 watt) all benefit from being easily installed into any filtration system using universal inlet & outlet – i.e. inside dia 1.5” standard waste, Key Terrain, Hunter, Osma, or Polypipe. The outside diameter takes pressure pipe coupling. All units are supplied complete with a set of stepped universal hosetails ranging from 0.5” to 1.50” inches, and make use of high quality double ended linear germicidal tubes. The Cloverleaf range have naturally been designed for ease in replacing all major components, thus ensuring a long lifetime. 

All Cloverleaf Ultra Violet Clarifiers are manufactured and conform to BS EN 60335-2-55 1993, and to BS EN 60335-1-55 1988, and comply to the Low Voltage Directive (Safety).

WHY BUY STAINLESS STEEL

The highly reflective polished wall finish of the heavy gauge body will do much to improve the general efficiency and performance of the unit, as well as overcoming any potential problems of the body cracking through heat and age. They also look great!!
