When treating my Aquarium Plants, it helps to know how much Phosphorus and Iron is already in the water and Hanna helps me to do that with ease and for the health of my fish, Knowing the PH and the TDS of the water Hanna makes it a lot easier than those test strips that the colors never seem to match anything. I wish that Hanna would make a complete Aquarium test kit for all the elements in an Aquarium for both fish and plants health.

Excellent products.

The service was great,while the Shipping and order was also on time and well packaged.

I submitted a question about how to use my new pH meter. The technical rep called me back the same day and provide detailed information. He was very nice, friendly and knowledgeable.

I bough the nitrate high range tester. I love it! It’s easy to use and highly accurate. So much easier to get my readings than the other testers I have used. The packaging and product is very professional. I would recommend Hanna testers to fellow aquarists and plan on buying more. Thank you Hanna!
