Seachem MultiTest Copper Test Kit

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

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.

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.
