Are water changes good, bad or indifferent when dosing CP in QT?
(I'm aware of the need to redose CP proportionately if doing WCs.)
Thanks,
Indifferent as far as CP is concerned, but beneficial if you are battling ammonia in QT.
Btw, when you re-dose CP after doing a WC, make sure to treat the source water with it (or at least mix it in a bucket before adding to the QT). Just like with copper, you never want the overall concentration to drop... even for just a second.
Thanks for pointing out the need to dose the new SW.
So, if not battling ammonia, or if you are controlling ammonia with Amquel, would you do WCs in QT?
Tank is almost a year old and has been stable since the initial cycle. I removed all the corals and inverts too. I fully didn't expect this after doing the reading I have on CP and the success stories of others.
CP just saved my butt thats for sure. I had to pairs of clown in diff qt tanks. But to make cleaning easier i divided a 20L and moved on pair over to the other side. Well neither pair showed signs of disease and have been doing good for about 1 week.
The day after i moved the new pair over i could tell they were off, breathing was weird and laying on their sides. The following day bam the new pair had broken out in what i believe to be brook (being clowns and not seeing ich prior) I right away dosed CP around 25mg/l or basically 1.8 grams of cp. They made it through the night and the following day they began to clear up. Now 3 days later they are no signs of disease and they are eating again and seem to be making a good recovery.
10 mg/l is only a preventive dose, 15mg/l for protozoan infection, and 25mg/l for all of the above and uronema.. Here is a good read for ya

IME, dosages > 10mg/l is overkill. In my initial tests, 10mg/l was effective for both velvet and ich. Some of the Canadian CP I acquired didn't seem to work initially and the dose was increased to 20 mg/l with a clinical response, but with the pharmaceutical grade stuff available, 10/l or 40/g should work fine. Save your money.
