30 Watt tubes – Replacement Tubes

A pond with clear water is an attractive feature in your garden, which brings many hours of enjoyment and relaxation.  A green pond is unappealing to look at and makes it difficult to determine whether your fish have disease or have injured themselves.  Algae also poses a threat as it starves your Koi of the essential oxygen they require.

An Ultra Zap pond UV will eradicate free floating algae and maintain a clear pond 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 pond and its environment.
