Good within a year

I bought these strips when I first started my aquarium and found them simpler than the drops. The 5-in-1 strips and the ammonia strips both worked well. However, after about 10-11months, I noticed the storage color for the ammonia is a little greener than it's original yellow (0ppm) color. This is probably just due to long storage time. Also, the Nitrate indicator is a little pinker than it used to be when I first bought it. I have about 10 of each kind of strip left. Once the strips start to get older, the ammonia result might be one step lower than the color indication in my opinion. If you need something super accurate, the dropper kits might be better. But this was good for basics, and 25strips last about a year anyway.
I would recommend this to a friend!

Ammonia strips totally inaccurate

IF the ammonia testing strips in this kit are correct, all my fish should be long dead.
Since I set up my tank and cycled it and added fish, the ammonia strips have CONSISTENTLY read over .5ppm per reading, and that's assuming that the colour on the strip (which is nothing even close to the colour scale on the bottle) is being read correctly. I have an in-tank monitor that says I have less than .02ppm, and I have used ammo-lock, but the ammonia strips continue to read incorrectly. I have kept the strips dry, followed all directions, and it supposedly expires in 2010, so I'm not sure what the problem is here.
Completely not worth the money, this thing has seriously stressed me out more than my fish.
The 5-in-1 strips work pretty great, although I sometimes have the same issues with colours not really being in the right range.
I recommend just getting the 5-in-1s separately and looking elsewhere for ammonia testing.
No, I would not recommend this to a friend.
