There are various test kits available, all relying on reading different hues and color tones. While many affordable saltwater test kits may be challenging to read, they should generally work. To begin with, it is crucial to know when the nitrogen cycle is complete in your tank, which involves testing for ammonia, nitrite, and nitrate. You can find more information on the nitrogen cycle in marine aquariums through this link [hyperlink omitted for rewrite].
When selecting test kits to purchase, it is recommended to start with ones that can measure ammonia, nitrite, and nitrate. However, if you plan to keep corals or heavily stocked invertebrates, testing for calcium, alkalinity, and magnesium becomes essential.
Although the options may seem overwhelming, do not stress about it. At the very least, getting the API Saltwater Master Test Kit will be sufficient to get you started on the right track!
