I'm not saying I don't respect your opinion, I just have a difference oof how I feel treatment should be rendered. I was merely stating that I do not see the point or need to lower SG
treat with copper. A SG
of 1.019 will not kill off ick. I will never use copper as a treatment again since I have learned of the negative affects it can have on a fish.
In your instance with such a large tank as Kevin stated treatments such as hyposalinty may not be practical for a number of reasons including $ and the large amount of time and effort it would take to do these large water changes. However treating such a large system with copper would also be costly and expensive and difficult to remove from the water, and even more problematic if left in after the recommended treatment period is over.
I"m speaking from a home aquarium standpoint here but the main purpose of a Q tank is to evaluate the condition of the fish and render the appropriate treatment necessary if there is a problem before the fish is released into the main display. Since most people use a rather small Q tank I see no reason why somebody would choose to use copper over hyposalinty.
I also feel as I've previsously stated that a freshwater dip will further stress out a fish and will not rid the fish of ick completely. If the correct treatment is initiated asap
a freshwater dip is not necessary due to the fact that ick cannot survive at a SG
.... but this is all JMHO
.. take it or leave it for what it's worth.
