API Amonia Test is bunk

Long after cycling my new saltwater aquarium I was getting .5ppm repeated readings over a period of several weeks well after into 3 months cycling a 75 gallon saltwater system with only 3 clownfish when using THIS test. So took a water sample to my local reef shop and found 0 ppm. So I googled this. Others had the same experience. This kits amonia test is bunk. Avoid!

Strong basic tests

For the nitrite cycle, these droppers are pretty good. The dip sticks are good for every couple of days, just to make sure nothing odd has happened, but for the serious tests, before adding a fish/invert or when you suspect something might be off, these droppers are a good test of the basic needs of your aquatic pals' water conditions. I recommend pairing it with other tests more specific to your sitch, such as the reef test kit for reefers, but for a good, strong, basic look at your cycle and pH+, this is a strong test kit.

Great Test Kit

First of all, the shipping on my order was super fast. I needed the kit to test the water for amonia on my reef tank and received it super fast. The packaging was great. I have performed various test so far and I love this product.

Test good quality so-so

The test work well but the quality of the chemical bottles doesn’t seal well. If the lay in their side they leak. Upon arrival several had leaked everywhere. Cleaned them up and as long as they stay upright they are fine. The test tube don’t seal great so during test where you have to shake vigorously for one minute , it leaks some. Overall happy to have them!

Cheaper than strips!

It was like chemistry class. Little easier to read the strips. I bought both the reef and salt water fish test kits. The ph readings where the same!
