Works as it says
Chewy is the best...I ordered as of my fish aquarium supplies from them.. fast shipping best prices around. An amazing customer service.. I would recommend this test kit for anyone who has aquariums
Bought this to test my tap water's hardness for my shrimp and snails. Directions are easy to follow and everything you need is included. Tests seem to be accurate so far based on other tests I've done.
tells me what I need to know
One of my test tubes came cracked (would have gave 5 stars otherwise) but the other tube was fine I didn’t realize there were two in there but overall a good product.
Great product works amazing to tell the hardness of the water is a life saver for soft water Fish
It tells me what I'm looking for
It does not work like the ones in your API Master Kit, it does have a color chart like you would expect, it indicates readings based on number of drops and when the test tube converts to another color. Read the instructions as you should, and it'll do what you expect this test kit to do.
Arrived in package badly but kit is amazing
Opened the package and everything was out of the box, but thankfully the glass test tubes didn’t break. The kit itself is easy to use and gave me a reading that seems accurate for my tank. I am a shrimp keeper so a kit like this is critical to my babies survival! Thanks again Chewy <3
Exactly as pictured.
Gets the job done. Accurate and has detailed instructions on how to use it.
Easy to use like all the other API items. One of the bottle was leaking and lost about 30% of the fluid. I contacted chewy and they sent a replace within a few hours. Very happy with the website.
Tried and True!
Very helpful in keeping my 50 gallon planted freshwater tank happy and healthy!
Perfect for trouble shooting problems.
I started having molting issues with my 36gal invert tank. Decided to get the test kit to make sure all was in order. After finding out the GH and KH was just fine I discovered the problem was my liquid fertilizers. It's always good to have test kits around when things start going south.
