My journey using Chloroquine Phosphate begins...

Day 97 update: Almost 100 days later, my PB Tang is finally in her new home - a 150 gal mixed reef. She's survived Ich, a 12 hr move, and living in a 30 gal tank (then sterilite container) for all of that time. See pics below!

Thats brilliant :fun2: well done
 
I guess it all depends on the half life in the fishes blood. In humans it ranges from 6 to 50 days from what I just read. Therefore the minimal time for elimination will be around 1 month, and max would be over 8 months in some individuals. that is just for one dose. Not sure why the big range, but if the same is true for fish, oral ingestion has possibilities.

Ya know, I hadn't considered that. The folks using Dr. G's should start a thread, and update us as to whether or not Ich eventually comes back after using it. I'd also like to know if anyone has had any negative experiences using it in a fully stocked reef tank.
 
It's ability to kill algae would concern me in the reef setting. I am going to experiment with feeding fish to find the lethal dose. I'll post results hopefully in sept.
 
Concerning oral dosage in a reef tank, what about the protomonts? Or would you feed CP for a couple months? I forget how long those protomonts can live, but IIRC it's quite awhile.
 
I fed for 3 weeks and it worked. I wish i had some more ick infested fish to try it. No issues at all with any corals or inverts.
 
Yes, but if one fish refuses the food, or doesn't ingest enough to reach a therapeutic level, it will fail. Assuming it works to begin with. The symptoms of ich will often disappear with improved water quality or development of partial resistance. It is not gone and will always come back however. Put a new hippo or powder blue tang in with water from your reef. If it doesn't develop ich, I would believe it works.

I like the idea and Wonder if injecting into mysis would work. We need to figure out the effective dose per gram fish and the lethal dose.
 
I had ick recuring every 5 days like clockwork. Fed for 3 weeks and it is gone. I have not seen ick on my fish during the treatment. It has been 5 weeks. All of my fish ate it eventually
 
According to dr g it does not take much for it to be effective. I think your more likely to overdose your fish then under dose. You can also mix with other food to dilute the taste. Just feed a little more. The food is binded very well.
 
I had a tank that I thought was free of ich for over 3 years. Never added a fish, but after a power outage and a temp drop it came back. The only way to know if you are ich free it to use your tank water on a highly susceptible fish. Sorry, but for good reason I'm skeptical.

Me too. Don't get me wrong, I want to believe. However, I also don't want people believing they've found a reef safe treatment and then if it fails or kills all of their corals, they write CP off altogether. Because I'm about 90-95% sure that CP works when added directly to the water in a QT environment. It's one and done, doesn't seem to have the side effects that copper has, and supposedly treats Ich, Velvet, Brook and Uronema. Talk about an all-in-one medication! Seachem or Mardel or some other co. that makes fish meds needs to bring this medication back to a LFS near you!
 
CP definitely works when added to the water. It is tough to find though. QS is readily available and also is very effective. I have just found it to be tough on the fish. I have used it in my fish only display that houses a skeletor eel. All of my fish including the eel refused to eat for 2 weeks and my spot fin butterfly had very frayed fins. The ick never returned.

One of my biggest complaints about copper is the side effects, especially the appetite suppression. And then there's the whole "don't use copper on certain fish" thing. Do you stay the course and hope the fish doesn't starve to death, or back off so the fish will eat but you know the disease problem hasn't been addressed? I've never used QS, but I've read about the various side effects. This is where CP has the edge IMO. I only noticed some slight appetite suppression at times when treating my PB Tang. But never enough to make me second guess continuing treatment. And I haven't noticed ANY side effects or symptoms when treating prophylactically, presumably to healthy fish. Nothing sucks more than a seemingly healthy new fish dying suddenly while being prophylactically treated with copper. You start to second guess your QT methods.

I always ride it out depending on the fish. If the fish starts to look emancipated i remove it from the tank and do tank transfers using rubbermaid tub. I try to avoid copper at all costs. I can tell you though feeding the fish rhe cp does not suppress the appettite like adding it to the water. You just need a longer treatment since your not killing the cysts in the water. I am shocked that not one of the big companies sich as seachem has come out with it yet. Its almost like if they cupramine would be discontinued.
 
There are some legal issues that I believe are preventing it. For a small company, side business with not much to lose, it might not be a big problem to get shut down for doing something wrong. Big company = big fine and problems if there is a violation of the law. much more to lose.

I'm not sue if it is OK to sell CP without a script. My understanding is that one is still required, But I do know tha drugs like accutane, Prozac and Viagra needs scripts and can be readily purchased online without one.

What about Dr. G's?

If they can sell frozen fish food with CP listed as the active ingredient, I don't see why they couldn't sell a pill or powder medication with CP listed as the active ingredient.
