ICH, Cupramine, Salinity & Temp?

[crissie]

Then perhaps you should do a little research. Even just a google search if nothing more.

And no, I'm not confusing anything.

 

[Deinonych]

Yes, I know. It's not false though. One can convert mass measurements into liquid measurements via a basic forumal of 1,000mg per ml. It's formed via displacement and is in no way similar to gallon/pound. One should know that liquids have variable weights - most especially in this hobby.

Not to derail this thread, but 1,000 mg = 1kg. Not sure how you are drawing the conclusion that 1kg of mass is somehow equal to 1mL in volume. That's some seriously dense liquid.

1,000mg is 1g! Not 1kg! You're right, that would be some seriously dense liquid!

 

[Deinonych]

Ugh...serves me right for posting before my morning coffee. You're right.

[edit] I still agree with reeferstace that mass is not relevant to determining the volume of Cupramine required for treatment.

 

[power boat jim]

First, weight does not equal mass. Grams are units for mass.

Also I believe that you are confusing mass with density. I stand by my comment that mL does not equal mg.

This is correct^^ these two units, grams and litres are seperate, they measure two completly different things and are not interchangeable. If you are supposed to get 100ml of a medicine and get 100 mg you may get too much or too little depending on the density of the medicine.

 

[DasCamel]

Ok.

Ok.

I understand the conversion the cris is trying to make. In some instances you can get them to "equal" but it is a poor way to communicate the result to others.

Botton line is, in any chemistry or physics course, using the terms in that fashion would equal a failing grade very quickly. Just don't interchange mass with volume.

 

[crissie]

Agreed DasCamel, however it's not me interchanging the two, it was the OP asking for mg/l dosage. It was only later he mentioned the 1ml/40l recommendation.

In an ideal world you shouldn't attempt to cross the two - but it can be done.

 

[yachtdr22]

Thanks all...
I understand the confusion... I wish seachem expanded on their instructions a little bit more...

I hope to use the .3818 x .40 x the # of gallons when I do a W/C.

No, it cannot and be done correctly. Mass does not equal volume. Period.

 

[crissie]

*sigh* Yes, it can. It can be estimated with a basic ratio of 1g/1ml and it can be calculated exactly with additional variables.

I'm a touch bored of your unwillingness to at least check whether or not what you are saying is correct.

 

[Deinonych]

The 1g/1mL ratio only applies to pure H2O (i.e. 1L of H2O has a mass of 1kg). Other liquids have different densities, so this is not a good rule of thumb to apply to all liquids (e.g. 1L of seawater has a mass of approximately 1.027kg, depending on salinity).

In the end, none of this is germane to the OP's question, and I believe he has the answer he needs regarding proper dosing.

 

[NHATRANG]

Seachem recommends: 1ml for 10.5g first dose to get to .25mg/l
you need to dose roughly 7.71ml.
7.71/3 = 2.56ml

I teach chemistry. My high school students know the difference between mass and volume and that 1mL does not equal 1mg.

I'm out. Have a great day. I hope you are not a pharmacist.

 

[yachtdr22]

I'm not sure I follow you. First, 0.25 mg/L is below the therapeutic dosage. Minimum therapeutic dosage for Cupramine is 0.35 mg/L. I usually treat at 0.40 mg/L for four weeks, ramped up over 5 days. If I were doing this with your setup, I would would dose a total of 12.34 ml (0.381 * 0.4 * 81). Divided by 5, that gives 2.47 ml per day. I always test after each dosage to make sure I'm not overdosing.

Chris,
I was wondering.. how do you figure out your dose to water change if you are in the 5 day ramp up?
I was thinking that if the dose was divided by 4 That would dose in even .1 increments?
My problem is that i have 4 pigs in the 75 and I am concerned that I will have to do a water change before i am @ target .4
I understand you can not dose Prime when using Cupramine?


Your thoughts?

thanks
Drew

i appreciate everyone's input....
the fact that there is a discussion makes me not feel like a total dumba@%

THanks all!@

wishing you all 4 leaf clovers!

How quickly is relief noticed to the fish as dosage is reached?
Should they stop flashing fairly quickly?

It's no different than doing a WC once you've reached the target concentration. That is, if you are at 0.3 after dosing 0.1 for three days, you would add the necessary amount of Cupramine to the new water so that its concentration is also 0.3.

How quickly is relief noticed to the fish as dosage is reached?

Once you reach the therapeutic dose, the fish should stop flashing within 3-7 days, depending on how long the trophonts have been attached. IME it's typically closer to the 3-4 day mark, since they are being treated in new water and are not being reinfected on a daily basis (since the copper is killing the theronts).

 

[snorvich]

Remember that the vulnerable part of the life cycle is the contagious part which occurs after the trophonts have dropped (usually at night) so you will not see relief until trophonts have dropped off during this cycle.

I think the biggest PAIN IN THE A** about treating with Cupramine is reading the damn Test Kit...

PLEASE.... who has some good secrets to comparing the sample and the strip???

I agree, it's one of the primary reasons I hate treating with copper. I too would be interested in any tips.
