Hi there! The proper way to use copper is in a QT with no sand or live rock in it. Here is a link with much more detailed info
Copper
We are happy to answer any questions that leaves you with.
Hello, I just put 2 small percula clowns and a small benghai cardinal in my 30G QT. They look healthy and are eating well. I plan on medicating for 30 days w Mardel copper safe followed by praz. Before I do, I have a few questions:
1. Does the 30 day clock start at first dose or when I reach the therapeutic level after a few days?
2. Once added, do I do any WC's or just monitor copper levels, water and fish? The instructions say to treat the replacement water w/ copper safe and this is what confuses me.
3. I assume I add copper if the level drops below. But, do I add the copper to the water BEFORE it goes into the QT? If so, I assume saltwater and not RODI, right? But what if it goes above....small water change and then adjust as necessary?
4. I have a sponge filter in my HOB, do I discard that once the copper cycle is over? Or, will copper removal procedures remove the copper from the sponge? I added biospira directly onto the sponge and I am concerned I would be tossing all the good stuff.
5. Finally, I plan on mixing some metroplex/focus w frozen food during the copper phase, ok?
#2 and 3 are what confuse me the most!!
As always, thanks so much!
