Easy to use

These strips are very simple to use. I wish I would have bought them a year ago when I first cycled my nano aquarium. It's great to see I have no ammonia ever now, and have a fully cycled and established nano aquarium. I'll definitely be using these when I get my new 30 gallon aquarium set up. I had a lot of problems keeping fish alive and keeping algae down for around 6 months, but aquarium co-op has helped me every step of the way, and now my tiny aquarium is flourishing (albeit now over stocked and over planted hence the new 30 gallon). I love aquarium co-op, and will always support their products!

Easy to Use Testing!

These test strips are extremely simple use and give quick results. I like not having to use two bottles of test chemicals to complete one test and I also like not having to set a timer while I wait for a result. I have 3 tanks now, so having a product that makes testing simple is a win. I will definitely buy these again.

Seems like a good product thus far.

It's hard to have a real comparison in such a short time frame but they seem pretty constant with my API master test kit but less effort (with 6+ tanks) far less time consuming. I do these every few weeks or if somerhing seems off - but still follow up with my master kit, for what it's worth
