Help your finned friends get the most out of life by testing their water quality often. Ensuring that the water they’re swimming around in is in good condition is essential for their health and wellbeing. PetSmart’s collection of water test kits and water quality testers will help your fish live their best life. Give them water they can thrive in with one of our water quality test strips or kits. 
At PetSmart, you’ll find easy aquarium test strips and complete water testing kits for both freshwater and saltwater fish tanks. Invest in a water quality tester to check pH levels and ammonia, as well as chlorine and chloramine, nitrites, nitrates, water hardness, and more. 
In addition to water quality testers and water test kits, PetSmart has everything else you need to give your fish the absolute best care, including:
And for all you new fish parents who are just getting started with your aquariums, we even offer aquarium starter kits and a full selection of aquarium products that make it easy to start and maintain a new aquarium.
PetSmart also offers convenient shopping with curbside or in-store pickup. Need something today? We have select items available for same-day delivery in most areas powered by DoorDash. For items you purchase frequently, PetSmart has Autoship that automatically delivers the items you want to your door as often as you’d like. Check the website to see what items are eligible.
