    525 STRIPS, and CHEAP!!!
    By Maridia
    NEVER NEVER NEVER NEVER!!!!! NEVER buy the one that comes with only 4 test strips! It's waaaayyy toooo overpriced! Always buy this one. It's cheap and it comes with 25 test strips that measure for Kh, Gh, Ph, Nitrite, and Nitrate (sorry no Ammonia). 5 stars!

    4Good enough for non-pros.
    By QuetiFifiDad
    I use this for a quick check of my aquarium and it does the job well. I am never a big fan of using the more expensive water test kits with multiple bottles and a test tube to do the job. I'm sure this is not as precise as those test kits, but its ease of use sure makes up the difference. Recommend it.

    3Convenient, but slightly difficult to read
    By Brandon Burnham
    Dip, swirl, remove and read- it doesn't get much more simple than that. I find that I use these more frequent than the chemical test kit because they're convenient, but I still got back to the test tubes every so often to confirm the results.

    I give this product a rating of 3 because the nitrite and nitrate pads turn a subtle shade of off-white/rose and it can sometime be difficult to discern the levels. Fortunately, this is at the lower end of the spectrum, meaning lower levels so it may be a moot point for you. I keep the chemistry of my aquarium at 0 for both nitrites and nitrates so I like to see the variances, even if only by 0.25.
