SeachemMultiTest Silicate Test Kit,75 Tests

This test worked well. The key to this test is ensuring you use the right amount of water to sample and waiting the time instructed in each step. Fill the pipette to the top of the throat (no lower, no higher) with the water you are testing. Then wait exactly the amount of time they say (I used a timer) between steps. Don be afraid of the "dusting" in other reviews. just get a little on the stirrer and stir. A few grains is all that is needed and if you go over a bit it doesn't affect the results.This is my water. I tested multiple samples from my tap water, RODI filter and saltwater aquarium to see where the Silicates are coming from. Once you mix the reagents to the samples as instructed, you compare the results to a gauge.Here are my results:The top left is the "calibration" test (included) of 6ppm.Top Right is RODI from my RODI filter. I got 0 ppmMiddle right is RO taken before the DI from my RODI filter. (its zero and the same as RO) I also got 0 ppmMiddle left and bottom right is my tank water. I did two tests at different times to see if they came out the same (and they did). this way I know I was doing them right I got under 1 ppm but not zero as I had hoped (diatom food in my tank)Bottom Left is my tap water (WOW). Off the chart and at least 25ppm.I interpret the results as this. My tap water is loaded with silicates and will filter it to an undetectable level. My tank has some (not zero). the result is the silicates are likely comming from my sand and rock (as I expected). The ditoms should consume the silicats over time.

Does what it says if you closely follow the instructions. Do not deviate from the instructions. I have been using it for 1 month now and tested many times on my supply water and the water in my tank. It is reliable in my opinion. Note that Some deviation from the instructions may result in inaccurate results.One thing i dont like is that the reference strip bars are too small and too close to each other, thereby making it hard to read the silicate concentration.

This was very helpful in testing our fish tanks to find what was feeding the brown algae. Turns out our city water has a lot of Silica in it and some phosphates. I used this kit to test our city water from the faucet as well as the tank water.I started by first doing an initial test using the sample water that comes with the kit to make sure I was doing it right. Sample tested at 6 like it should so then I proceed to test the fish tank and faucet water. Then we purchased PhosGuard to put in the filters to remove the silica and phosphates. I continued to test with this kit weekly, to watch the silica levels go down in the fish tank. And now we know to use filtered water for the tank to keep out the silica and phosphates to begin with.

This kit is very easy to use and comes with a handy color chart to compare to the test sample. This helped me understand what was happening with my aquarium water and why i was getting a lot of brown algae. I added phos-zorb to the tank yesterday based on the results given by this kit. Thanks Seachem.

I use many Seachem products but this product is not helpful. It seems simple enough but the measuring is imprecise and not much info to guide one if you have questions. The method to actually read the results is a sliding piece of cardboard that is useless. I have tried it several times and still can’t say what the silicate levels are.

I purchased this kit for testing silicate in my 28g Reef Aquarium. It doesn't seem to show any noticeable results even when using the low rang part of the test. I even tested my tap water with it and could barely pick up a reading. I've followed the test procedures correctly and have achieved the same results numerous times. This does not necessarily mean that the product does not work. It is possible that I have zero silicates in my aquarium and close to zero in my tap water but this seems unlikely to me. It also includes a certified standard/solution that you can test to double check that the kit is working properly. I couldn't seem to get accurate results which is another reason I'm not in favor of this product. Anyways, I give this product three stars because upon using the test kit, I receive a very low level of confidence in the results. All my other test kits and electronic testing meters leave me feeling certain. This does not.

This is the only kit for silica I found, so I am happy for it.I followed the instructions, and I got reasonable results. Includes a positive control, and you can use pure water as a negative control. So, it seems it works.However, four products to measure it... too many steps... It is ok, but it could be simpler (4 stars)Also, in one step, you have to put a stick on a white powder and then move the powder to your testing solution, mix, and wait for the color to appear. Every time you put the stick, you get different amounts of powder. It doesn't sound too accurate. Not sure what the powder is doing... and if it matters, how much powder do you add.So, I tested the following:bottle water 0ppmTap water... high ppm, not sure how muchFish tank, I would say 4-6 ppmReference from the kit. Do they say how much you should read? I would say 10ppm?

Worked as needed.

Works like a charm to test out your water easily

Facile e molto preciso.

The test works, but it's hard to define the exact level of silicates, especially if it's close to 1

No hay algo que no me guste. Supongo que se requieren los cuatro reactivos y los dos periodos de espera para obtener la lectura. Me ayudó mucho para controlar una plaga de diatomea en acuario de agua dulce. Definitivamente parecen correlacionarse la cantidad de silicatos y la cantidad de diatomeas.
