    Yes it will work just fine.

    It takes a baseline reading before reagent then the actual reading after. So it's accurate even with the tinted water. I've checked it several times. Test, dose Furan, test.... Same reading both times.

    Sounds good.

    What level should I bring copper to?

    I must be doing something wrong with my math.
    The tank I'm using to quarantine all my fish in 117 gallons with the water in the sump.
    I'm using Copper Power.
    I dosed 3/4 of a oz. on the 15th, the 16th, the 17th and a full oz last night for a total of 3.25 oz.and my Hanna checker says the ppm is 0.49.
    That can't be right?

    I had to add way more then recommended..presumably to my bio media and sand bed absorbing some. However, once I got it up to therapeutic levels it was stable.

    The dosing calculations presented in the first post and a couple of other posts here work.

    For those interested in using a metric approach, here's one:

    Based on the bottle dosing instructions, the calculated copper concentration of Copper Power is 6.40 mg/ml.

    Take your desired dosing endpoint in ppm, and multiply by your tank volume in liters.

    This gives you the total amount of copper ion you want to add in milligrams.

    Take this number and divide by 6.40, and you get the total mls of Copper Power to be added (in divided doses.)

    Using the example from the first post:

    40 gallon (151.4 liter) tank with desired copper level of 1.75 ppm (mg/liter).

    1.75 mg/liter x 151.4 liters = 264.95 mg copper to be dosed.
    264.95 mg total copper needed divided by 6.40 mg copper/ml Copper Power = 41.4 ml Copper Power to be dosed.

    Can the seachem kit read copper power effectively?

    Hi all,

    just read through the entire thread. Just wanted to clarify, if I move the fish to another sterile QT Tank after 14 days, do I need to continue dosing Copper Power at 1.75ppm?

    If so, what is the reason to moving them to another sterile QT tank instead of running the full duration of 30 days?

    The sterile tank post transfer is copper free.

    Is there a good resource to know what copper levels some sensitive fish like Angels can tolerate?

    What kind of angels? I have treated most of the common to the hobby angels. Have a passer, goldflake, and scribbled in 2.25ppm copper power as we speak.

    The API kit always read low for me as well. Which is what led to overdosed copper.

    How many total ml have you dosed into your 10g.

    Then trust the Hanna checker. 13ml into 10g should yield 2.25ppm. I'm guessing the tank holds slightly less than 10 gallons plus a little displacement for equipment, pipe, whatever you have in the tank Etc.

    So the reading of 2.66ppm you are getting is accurate.

    I would like to get a Flame angel soon, but also other fish like wrasses. I just want to know if there are some fish I need to treat lower or different then 1.75 ppm. Or is it a matter of perhaps ramping up the dosage slower with sensitive fish?

    Honestly I use the same process and Cu level for all fish. I've treated several Wrasse including leopards and anampses. Never have an issue.

    I start them in 1.50ppm and take them up to 2.0ppm over a few days.
