Hard to Read By Batfish Aquatics on 7/14/2016Batfish Aquatics wouldn't recommend this product to a friendThis test kit is very easy to use; however, the colour charts leave something to be desired. You have to match colour looking both from the top and from the sides. I found that the gradation on the charts was simply too close to discern any variation. Plus, distance from the vial mattered A LOT. Hold it at arm's length, you'll get one result, hold it close to your face, you'll get another. . . . Makes for a less than reliable tester!
Great Product By Jonathon on 11/26/2012Jonathon would recommend this product to a friendI have been using this test kit for about 6 years. Never had any problems. Seems to be accurate and easy to read. I would note that I can only compare it API test kits however.
Questionable By Robert on 8/23/2012Robert wouldn't recommend this product to a friendI have this kit to check my RO system and I while I do like the straightforward reagent procedure, I do not like the "color matching" approach. I cannot really state with any confidence that that I can discern the fine color gradations on the chart.
Great kit By Joshua on 2/27/2012Joshua would recommend this product to a friendI use this when setting up a new reef lets me know for sure how long and what kind of diatom growth I have and when it will most likely end!
Much Better By Brian on 8/4/2010Brian would recommend this product to a friendI tired using Seachem's test for Silicates and it was a pain. I am a fan of Seachem's products just not there test kits. This test kit by Salifert is the best I have used. Buy this kit if you want an accurate easy test kit to use for Silicates
