The API Freshwater Master Test Kit is an essential tool for maintaining a healthy aquarium, and it has been a game-changer for my 29-gallon newly planted tank. This kit provides everything you need to monitor critical water parameters, including pH, ammonia, nitrite, and nitrate levels, ensuring a safe environment for both fish and plants.The instructions are clear and easy to follow, making it simple to use even for beginners. The color-coded charts are accurate and help you quickly interpret the results. I don’t like the plastic tubes. They used to be glass. That’s why it’s 4 stars and not 5.Since using this kit, I've been able to keep my water parameters in check, which has made a noticeable difference in the health of my plants and fish. It's also cost-effective, offering up to 800 tests, so it lasts a long time.Overall, the API Freshwater Master Test Kit is a must-have for any aquarium enthusiast. It’s reliable, easy to use, and provides peace of mind knowing your aquatic ecosystem is thriving. Highly recommended!

Me llegó un kit en forma de caja, diferente al que se muestra en la imagen, y por otro lado, estuve viendo videos y las muestras deben de venir selladas en mi kit llegaron 2 abiertas y parecían ya tener uso.

The test strips I was using read between 6.2 to 6.8. I have hard water. This API kit says 7.8. I’m so glad I haven’t decided on the fish that’ll be living in this tank, and so glad I used this kit!

Gracias al apoyo, asesoría y calidad, pude darme cuenta con este test que mi estanque nuevo tiene Amonia, sino me hubiera dado cuenta que tiene .50 ppm de amonia, mis peces de 17 años, pudieron haber muerto. Gracias por su apoyo, los recomiendo ampliamente.

Se recomienda ver los videos de su uso para una medicion correcta, leer bien el instructivo ya que cada medicion requiere distinta cantidad de gotas y un proceso distinto.

I have been using this Master kits for a long time. Very accurate compared to the paper strips, which I have not used in years.

We have a 25 gallon long tank for our axolotl. Since the animal needs specific water parameters, we use this tester kit weekly to ensure we are keeping the water at correct levels. My 10 year old son has learned to do the testing himself, and he finds it simple to use. After our first 3 weeks, this tester kit revealed that we didn't have enough ammonia to keep the bacteria cycle alive. So, we added a few goldfish and everything balanced out again. Our axolotl would have died if we hadn't been testing the water.

The kit is very accurate and user friendly. The seller gave me an upgrade on the kit for free because they sold out of the other. Good customer service.
