API PondCare Mars Copper Test Kit

I was treating for anchorworm and using the copper medication. This shows you a color indicator and matching scale. All you do is fill a small vial with tank water and add 10 drops of a solution. You compare the color, its all easy.

Bought this copper test kit as it is compatible with Copper Power in a QT. Seems to work just fine and I will purchase another one when needed.

As described. Fast shipping. Quick results.

This copper test kit worked well when I had a bout of ich that I needed to treat in my 55 gallon tank -- I used Mardel Coppersafe (now being resold again by Fritz Aquatics). I didn't have any trouble reading the level of copper when I looked down through the tube after placing it on a light colored surface (sheet of paper works well). I will say that this kit did NOT work with the Kordon Copper Aid that I originally purchased from Petco, but seeing as I ended up having to buy the Mardel to get rid of the ich, I think it was probably something with that medication and I was afraid of overdosing because the instructions and the level of copper according to the test kit weren't even close in lining up.All in all, recommended if you are treating your tank with a copper-based medication. As a side note, my tank is planted and has black fin corydoras in it and both suffered no ill effects.

I only needed to use it once so far.

Don’t even try to buy this test kit.. it’ll just have you overdose your tank. Buy the Hanna tester OR follow the directions on the bottle of coppersafe or whatever you bought. At 2.5ppm this test showed me 1.5ppm. Coppersafe instructions came out to be exact when tested with another reliable tester

My new fish started to get the white spots on it. Ich was present. Lost that fish. Treated the tank with CopperSafe and have kept the rest alive. With this treatment I didn’t have to change all the water or raise the water temperature.

Terrible to read accuracy. Showed I was much lower than .5. I didn't trust it so I purchased the Hanna copper test which is much more accurate at a reading of 1.08. I lost a blonde naso and a wrasse because of this. Cupramine so high is no good. They should stop selling this product.

Works as intended

This test will give you a rough idea of copper levels in your tank. If that’s enough for you, then I recommend it.

The reading is negative so hopefully that’s correct , however glass tube handle very carefully although it’s kinda impossible since it has some child lock cap so you have to kinda wiggle it good to open , mine cracked on first turn

It's easy enough to use. Reading the result is a bit iffy made even more difficult because the colour chart was missing. A quick refund followed which was good. I have assumed that with absolutely no colour showing in my test sample there is no copper. To be sure I have sent for the Seachem one. If I don't update this review please assume the results agreed.

Dosing my marine QT with culpramine, a non-chelated copper which any copper test should be able to pick up.This test would have had me kill my fish. It reported a value of between 0.1 and 0.2. My usual and trusted (albeit expensive) brand of test kit reported bang on 0.5.It’s also almost impossible to read between 0.2 and 0.5, the colours are almost identical according to the indicator card.Do not buy this junk. I use this brand for other tests, but do not buy their copper tests kit, mine is now in the bin where it belongs.
