Simple review

This is widely used all around, most info is available via google but I have compiled here what I've found and what I've learned.
This kit covers most things the hobbyist will require, you can test for ph,high range ph, Ammonia, Nitrite and Nitrate, it includes 4 glass test tubes (reusable) and an easy to read manual.

However if you wish to also test for general hardness (Gh) and carbonate hardness (Kh), both aren't as much as a problem for beginners but might be culprit to some imbalances later on. I'd suggest you compliment this kit with that. But it is not necessary.

Quick tip (Make sure you thoroughly mix or shake Nitrate test bottle 2 to get accurate results)

Overall great product, will outlive strips in overall uses, but it takes time to use.

Exactly as advertised.

Solid kit and good expiration date. I’ve gotten expired products from my local fish store on occasion, the co-op lives up to their reputation. Great quality.

API color chart

The kit helped me a lot getting my aquariums in balance. Great tool. My only criticism would be the color chart in the booklet. It is kinda cheesy. The colors really don't match up accurately with the test tube results. Ya kinda have to use your imagination. It is still better than sticking your finger in the tank and tasting it for water quality. LOL I love Aquarium Co-op and support them when I can.
