Agree! loving it!i have some wrasses and a clarion angel in 1.99 and they are eating and doing well.. Nice to have the Hana .. it is for a sure a game changer..
Really hard to tell because the camera might capture a different color. Also API test color should be determined in indirect sunlightUsing coppersafe and api. What level would you give this.
It’s been a while since I used api, but aren’t you supposed to look from the top of the tube through the bottom?Using coppersafe and api. What level would you give this.

Honored.... I am a big fan of yours!^^ Yes, with the white part of the card on the bottom.
Well shoot. Shows how mich I read directions. Im just gonna buy a hanna and take the guessing out of it.^^ Yes, with the white part of the card on the bottom.
Been using my Hanna for the past few weeks. You will be happy.Well shoot. Shows how mich I read directions. Im just gonna buy a hanna and take the guessing out of it.
Probably, but I normally don't see that big of a fluctuation with my copper checker. Are you sure you are getting it very clean and have the 10ml mark facing forward each time?Hi. I got my Hanna Checker recently and I tested for copper in my QT. At first it read at 0.32 then a second test immediately after revealed it to be at 0.25. Is it safe to assume that I have a copper level of around 0.27-0.3? Using Cupramine btw
+1 also make sure you get ALL of the reagent into the cuvette.Probably, but I normally don't see that big of a fluctuation with my copper checker. Are you sure you are getting it very clean and have the 10ml mark facing forward each time?
Sorry for the confusion about the mls. The API kit calls for 5mls of sample water so I use a syringe to take 5mls out of the tank and place in the test vial supplied by the test kit. When all the water from the syringe it places in the vial, it goes past the 5ml line on the test vial.
All of the color kits are pretty inaccurate. Seachem kit is specifically designed to be more accurate for cupramine, their copper product. This is ionic copper with a useful range below 1.0.Why do you say the Seachem kit won't work for Copper Power? The kit says it works on chelated copper and my first measurement at 1.0 seemed accurate.
I don't want to kill my gem tang so if I need a Hanna checker I'll go buy it. But isn't my seachem kit ok?
Hello Humblefish.Below is a list of the most commonly available copper products, their therapeutic ranges and compatible copper test kit(s):
In addition to the aforementioned hobbyist grade test kits, below is a highly accurate "professional grade" test kit capable of reading all forms of copper:
- Cuprion (0.20 ppm): Seachem or Salifert copper test kit
- Cupramine (0.4 - 0.5 ppm): Seachem or Salifert copper test kit
- Coppersafe (1.5 - 2.0 ppm): API copper test kit
Kordon Copper Aid(1.5 - 2.0 ppm): API copper test kit(Avoid this brand of copper; it's too watered down)- Copper Power (1.5 - 2.0 ppm): API copper test kit
