Hanna Marine Ammonia Checker HI784

Very easy to use and clear instructions. So much easier to use than the drops Good quality

Works great. A little hard to do at first but it gets easier.

This Hanna Marine Ammonia Checker HI784 is a fantastic tool for maintaining a healthy marine aquarium. It's incredibly easy to use, providing accurate and reliable ammonia readings in seconds. Monitoring ammonia levels is crucial for fish health, and this checker makes it simple to keep a close eye on water quality. Highly recommended for any serious saltwater aquarist!

love this product!!! all i can say is read the instructions and follow them exactly to the second! the tests will fail without percision. Trust me, after the 15 minute result wait time, along with the pricy reagent packs, you want exactness.

I wouldn't buy this again. I use a couple of other Hanna readers. They are quirky, but I can get them to work. The ammonia checker has never worked for me. It has several steps involving drops & two different reagents. And, if something goes wrong, you have to use more drops/reagents, etc. They aren't cheap when you run out. Another problem is that the reader itself does not function as described. HANNA provides a work around but it would be better if they fixed their product. Stick with the API test tubes & color charts.

Love it's good giving a accurate number the no chart with it like my API kit but I just looked the reading was good for a new tank cycling is finished.

Great checker. Just wish the packets were easier to pour.

Lo mejor

As described

Really appreciate getting digital readings when trying to cycle an aquarium. Only part I don't like is that it only goes to 2.5 ppm, but this is still very useful used in conjunction with another cheaper and less accurate tester that goes beyond 2.5 ppm. I'd buy it again. I can't find anything better.
