66 A large part of the work is now done – the pond finally gets its shape and can be filled with water. Remember that water is to fish and plants what air is to humans. You should therefore give this special consider- ation. Preferably, tap water is used for the first filling. It hardly contains any undesirable substances that adversely affect fish and plants. Well water The composition of well water strongly de- pends on the environment and thus may be an incalculable threat. Rain water Rain water contains very few essential min- erals. Heavy rainfalls can thus adversely affect water quality. However, small amounts can be used for topping up the pond. However, you should add sera pond bio balance before pouring it into the pond as to compensate the mineral deficiency, and sera KOI PROTECT for binding harmful substances. Tap water The strict quality requirements imposed on tap water make it an ideal basis for pond water according to nature. Now add sera KOI PROTECT for conditioning the water for fish and plants. Possibly present heavy metals and chlorine are bound this way and lose their harmful effects. Water quality is crucial for a maintenance friendly pond. Poor water quality may cause stunted plant growth, algae blooms and even fish diseases. For preventing this, the most important water parameters should therefore be checked regularly in every pond, independently from its size. sera offers the sera Quick Test to do so. Simply hold it into the water and read off the most important parameters within a minute. We recommend the sera aqua test-set for more exact measuring, and the sera KOI AQUA-TEST BOX for experienced pond keepers. Water at last! A tip: Control your water meter when ﬁlling the pond. You can determine the exact water amount this way. This is required for dosing pond care products or treatments. It also allows determining the maximum number of ﬁsh you can add and the required ﬁlter performance.
