Today we are going to share which water parameters you need to test for in a fish-only or reef aquarium, explain how these parameters effect fish and coral as well as provide tips on how to choose the right test kits for your tank.

Some hobbyists claim they can tell how good or bad their water quality is just by looking at the tank. The reality is when the water quality is so poor that you can tell just by looking at it, you've already subjected your fish and coral to lousy living conditions far longer than you should have and fixing the problem will now require greater effort.

Keeping your aquarium water parameters stable and at ideal levels is crucial to the health and well-being of the animals in your care. That’s why it’s essential to test your water regularly and log the results. Actively monitoring your water quality helps you identify trends or notice changes before they become problematic, making it easier to resolve any issues that may be develop.
