Great Product.

Excelente, medicamento.Quito los parásitos en poco tiempo.Hay que tener cuidado con la dosis, pero muy bueno.

Needed to get a few copper tests done on my aquariums once again as I do quarterly benchmarks my tanks for various water parameters. Since my previous kit was compete I grabbed another kit, this kit.I've used many different brands for various test kits to measure everything that can be measured for aquariums however I always come back to Seachem as one of my trusted brands because I know the result will be accurate. Another big thing for me is that this test kit is easy to read. Some other brands of test kits have difficult colors to gauge the slight shade difference however I find the blue hue with this kit makes it easy to read (i'm not alone with this). The included sliding window which you can train your eye on a specific color shade is a plus as well. I wish all brands had this type of color window slider no matter what is being tested (nitrate, phosphate, etc. etc.)This test kit is extremely easy to use. I'd first suggest to use the given benchmark liquid and test that. The manufacturer does not say it needs to be done but as a rule I always verify things first. So....first verify that the test is working properly it also serves a 2nd purpose which I state below. After that, measure your aquarium samples as you wish.Easy PeasyTO BENCHMARK:- For a benchmark test grab the white test tray (has the 6 different little liquid cup holders) and fill almost to the top one of the cups with the 'Copper Reference' solution. They say to do x2 of the small clear plastic pipette to fill the tray however ‘ fill almost to the top ‘ does the same thing. Don't fill the cup so much that it will leak out of that individual cup holder. Just make the solution basically level with the top of the cup.- Add 3 drops of liquid from the bottle marked 'Copper 2'. (make sure 3 drops)- Last step is to get a LIGHT COATING of the white powder on the plastic stir stick from the small clear plastic vile. This vile is not marked however it is the one that has the powder. TAP the stir stick in the vile to remove any excess. (I’ll give a tip below) Now use that same stir stick that has the little bit of white powder to stir the reference solution. Stir for a few seconds to mix the powder and liquid together well.Now just sit back and wait. They say for non-chelated wait aprox 4 minutes and read. For chelated wait for aprox 15 - 25 minutes. In my own usage 4 minutes and 15 minutes has always worked just fine.Finally hold the sliding color window close to the white plastic cup that has our test liquid. Slide the window back and forth until you get that perfect match...it will now line up over 0.5 ppm. Done and done!The reference liquid will always give you a 0.5 ppm reading. Again Seachem does not say this needs to be done to use this test however I always teach people to do this as a first step because it trains our eye how to read the color properly. We know it is 0.5 ppm so we can match up the color easily...and in turn our own sample tests we can better gauge color I feel.TO TEST YOUR SAMPLE:Steps are similar to benchmarking.- fill one of the cup holders nearly full of the aquarium water you want to test- add 2 drops of liquid from the 'Copper 2' bottle (make sure 2 drops)- get a LIGHT COATING of the white powder on the plastic stir stick from the small clear plastic vile. TAP the stir stick in the vile to remove any excess. Now use that same stir stick that has the little bit of white powder to stir the reference solution. Stir for a few seconds to mix the powder and liquid together well.Now same as previous, sit and wait. 4 minutes for non-chelated and 15-25 minutes for chelated.TIP: The tip for the white powder is that a LIGHT COATING is needed only. It is a coating on the stir stick…the stir stick is not used as a spoon. I find people overload the stir stick with wayyy to much product. If people run out of the powder this is the reason, I’ve seen people do this countless times. I've never run out of the powder before the solutions.TIP: One final tip, the blue hue solution can stain the white 6 pack cup holder so I'd suggest to wash it out after each use than letting the solution dry in the cup.I will say if anyone has a question about this just let me know, I'm more than willing to help you out with the kit.An honest review from a dedicated aquarist

分かりづらいがこれがましかな。

This test kit works awesome. I was really skeptical about the effectiveness of this test kit in conjunction with Cupramine copper treatment, after reading lots of mixed reviews about the overall quality of the test, misleading amount of tests in the kit, etc. After performing 2 tests with the kit, I couldn't be more happy with both the results and the quality of the kit. I am treating a 10 gallon saltwater tank, and I used Cupramine at the recommended dose, following the instructions on the bottle EXCEPT I dosed the 2nd half of the Cupramine only 24 hours later, contrary to the directions to dose the 2nd half 48 hours later (I was losing fish rapidly, it was an emergency situation). This had no negative effects on my 5 suriving fish whatsoever (4 Chromis's, 1 Clownfish). The following day after performing the final dose, I could literally see the white spots falling off my Clownfish. This was indicating to me that the copper treatment was literally forcing the parasites out of the fish, killing them all off the in the final stage of their life cycle. A few days later, all of my fish have been extremely healthy and well, no white spots to be found. I cant wait until my display tank has gone fallow long enough so I can put the fish back in their true home!Notes about the test kit: You really need to keep it simple. Lots of people in the reviews say how theres no way there are the amount of tests in the kit that they advertise. I disagree. The test kit 100% does include enough materials to perform at least 50+ Copper tests (who even needs to test copper that much?). You need to follow the instructions CAREFULLY but at the same time DON'T OVERTHINK IT. I found that leaving the test sit for 15-20 minutes gave me the best results (you'll understand once you buy it). The 2nd picture is the 2nd test after I added 5 more drops Cupramine to my 10 gallon, achieving the final goal of 0.5mg/L of copper10/10, I would buy it again if I ever needed it
