When and why testing pond water is important is Eric's focus today. He shares his decades of experience with fish keeping, arguing that while some professionals emphasize frequent testing, it isn't always necessary in established, healthy ponds. He highlights situations where testing is vital, such as during the cycling of a new pond, when fish are being temporarily housed during renovations, or if fish show signs of distress. Eric also touches upon testing for salinity, particularly in the context of quarantine or figuring out pond volume using salt and a hydrometer, and mentions his perspective on the nitrogen cycle and pH testing. Ultimately, Triplet asserts that visually assessing the pond and fish, along with experience, can often indicate water quality issues before formal testing is needed.
