You need to be really simple about it
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 copper 10/10, I would buy it again if I ever needed it

Necessary for anyone using a copper based fish medication
This test kit is a must-have when medicating with a copper-based medication. It is especially useful when using copper to eradicate a pond snail infestation with their Cupramine product. With this kit you can make sure the copper levels are high enough to kill the snails, but not dangerously high for the fish and plants in the tank. It's a little complicated to perform, and I would deduct half a star if I could for not having a clear line on the pipette to show exactly how much water to test. Also, coating the little stir stick with the powder and having to wipe it off after each mixing seems imprecise to me. I do think the color scale with the windowed sleeve helps for evaluating the color results. You can test six different samples at a time, which is nice for comparisons.

Good test kit, a bit tricky to use
When it comes to copper test kits, there are not too many choices out there. The Seachem copper test kit is a well designed, well packaged kit that yields accurate results. Included with the kit is a plastic well where the water and reagents are mixed, 2 reagents, a pipette (dropper), a mixing stick, a color guide and a reference sample. Many people have complained about this kit but you must take these comments with a grain of salt. Seachem has created a test kit that is priced for the consumer and at that price we cannot expect it to as sophisticated as a lab quality test, that said I think it works very well. The general steps of performing a test with this kit is to fill 2 pipettes with aquarium water and drip them into a slot on the plastic well. This part is very easy. Next you put 2 drops of Reagent 1 into the well, also very easy. The next part can be a little confusing. Reagent 2 is a powder that comes in a small capped container. The instructions say to open the container and using the mixing stick coat the stick with powder and mix it into the well. At first glance you will think you don't have enough reagent (powder) in the container as it's impossible to coat the mixing stick, especially if you think you will be performing multiple tests. I called the company and they said it takes only a few granules of the powder to perform the test so all you really need to do is dip the stick in, twist it once or twice and you'll pick up enough granules. Next you mix the granules into the well and wait a few minutes. Several minutes later the well will start to turn blue depending upon how much copper is in your water. For those that think the test is not working (like me the first time) Seachem has included a reference sample. If you perform the test as I described above using the reference sample, you will find that the copper reading will be 0.5ml/L. I've said it above but I'll say it again, it's a good test kit. Don't be scared away from the bad reviews.

Works
This kit is really necessary when using copper. I am dosing a 60 gal saltwater tank. I followed the direction for the initial dose (1st dose then 2nd dose 48 hours later) and it brought the copper level up to the optimal 0.5 level exactly as promised. However, one week later, the level had dropped to 0.2, which is the lowest threshhold for effectiveness. Had I not had this test kit, knowing the copper level and how much to dose for subsequent treatments would be impossible. As someone already indicated in another review, the powder should be used very sparingly...as long as you have a few grains of the powder on the stick, the test results will be fine. You barely have to touch the powder with the stick to pick up enough of the reagent to be effective. If you see granules floating in the solution after mixing, those granules are the undissolved/wasted reagent, which should give you an idea of how little of the powder you need for an accurate test result. Overuse of the powder won't give an inaccurate result, but you want to have enough for multiple tests when adding more Cupramine to your tank to get it back up to theraputic levels in subsequent dosing. Reading the results is a little frustrating, as it is hard to really gage the color matching, but as long are you are close to the 0.5 level, a little variance up or down in actual concentration shouldn't make a difference. It also helps to have a second set of eyes offer an opinion on the color matching.

0, 1, 2, 3, 4, 5 drops per gallon...
You are looking at freshwater tests I ran with 0,1,2,3,4,5 drops of Cupramine per gallon. 2 drops should read as 0.25. Is that what the chart shows? Not at all. Can the kit be used with a faulty chart? Not really. Every time I need to measure the copper in my tank, I need to create new color references using fresh water in a bucket. SeaChem provides reference water to check your results against. Should be 0.50 ppm but it also is very dark and doesn’t match the reference chart. Here’s the biggest problem (if a faulty reference chart isn’t a big enough issue): The package says that its good for 75 tests but it’s actually closer to 10. The reason is that if you follow the instructions they provide using the tools they give you, there’s not enough powder. I bought two of these tests kits so that I could try using the kit per the instructions, scratch my head and run tests to confirm that the reference chart is inaccurate and then buy another kit to run 9 tests that show me the true colors after adding additional drops or Cupramine. I’ve already started treating with Cupramine so now what? You’ve read the forums so you know my best option now is probably to try the Salifert test kit. So Cupramine doesn’t play nice with most copper test kits, it ruins your ammonia readings causing you to need the SeaChem free-ammonia kit, plus, the copper test kit you buy from SeaChem is inadequate due to accuracy problems and insufficient materials. These test kits need to work with their product.

Just OK
Eek not a huge fan of this test kit. I found it very hard to read. Comes with a scale to compare your results to, every time I tested, my results had a very different blue hew than anywhere on the scale. Works well enough to get a rough estimate but that’s about it. It was relatively easy to use the test kit though. I would also note it appears very consistent, I once tested the same water three times in a row trying to decider my results, each test at least came out identical.

Another fantastic Seachem product
This test may seem scary and intimidating at first. However, it is not. When I first started using it, I was like what the heck? However, I have learned to really become a pro at differentiating the colors to what level of copper is actually showing. The one thing I can recommend to someone who is new and/or unfamiliar with this copper test is to use the water sample Seachem provides to show you the color of blue you are to expect. I use this test daily on certain tanks being treated with Cupramine and I am to a point where I can look at the test sample and know immediately where my color lies. I also recommend keeping Cuprisorb on hand just in case you do overdose and/or not sure how much cooper is in the tank. Cuprisorb will immediately start removing the copper. I also recommend when treating with puffers to keep the level at a 0.3 and not 0.5 (more so for a Porcupine Puffer). I also highly recommend doing a 6 week course of copper if treating within your main display tank to make sure you eradicate the ich parasite. The ich parasite has a life cycle of 3-28 days. A constant cooper level for 6 weeks will ensure that you have successfully eradicated the ich parasite.

Easy To Use & Includes Reference Vial
If the instructions are carefully followed, this is a straightforward and fast test for monitoring Cupramine levels. Scale is from 0 to 1.0 mg/L. Since treatment dosage should max out at 0.8 mg/L per Seachem, this test should be accurate in managing Cupramine. You will need an eye capable of discerning very finite shadings in the aquamarine/blue scale to white - this has tripped some people up. Using API's Copper test kit on the same water sample, the Seachem test detected a therapeutic dose of copper while the API test indicated zero copper. Word to the wise. Worth noting, Seachem states in their instructions that this test can also be used for chelated copper. Cupramine is not chelated. Strongly recommended.

accuate and my goto brand
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 Peasy TO 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

Reagente due insufficiente
Il test acquistato non mi ha soddisfatto, è indicato per effettuare 75 test, ma il reagente numero due fornito in polvere è veramente in quantità insufficiente nonostante si seguano le indicazioni in maniera rigida. Inoltre la lettura rispetto alla scala risulta essere difficoltosa. Rapporto qualità prezzo pessimo. Non ho effettuato il reso solo perché ho aperto il reagente liquido, ma avrei restituito il prodotto volentieri.
