Buying advice

Consider your tank type (freshwater, saltwater, pond) and the parameters you need to monitor. Liquid test kits are more accurate but take more time, while test strips offer convenience. For reef tanks, focus on calcium, alkalinity, and magnesium. Buying separate test kits for specific parameters may be better than a general kit if you need high precision. Check reviews for clarity of instructions and longevity of reagents.
