Most pond owners have realised that even clear water can contain undesirable substances. You need water tests for a correct diagnosis.
The small JBL test case gives each every pond enthusiast the opportunity to determine their pond’s most important water values quickly, easily and precisely. The JBL test CombiSet Pond contains tests for carbonate hardness (pH stability), pH value, general hardness (mineral content), ammonium/ammonia (toxic nitrogen compound), nitrite (fish poison) and phosphate (algae nutrient). What makes these JBL water tests very special is the comparator system, which simplifies the reading of the colours during the tests, while also taking the intrinsic water colouration into account. You can’t test more precisely and easily.
