I've read this thread numerous times, great information in here. Thank you to everyone who has contributed. I recently went through a Velvet outbreak in my tank that wiped out 90% of my fish. I managed to save 5 wrasses with a formalin bath and started CP on them.
I acquired CP from the pharmacy in the forms of 250mg tablets. For anyone who has tablets, it contains fillers and binders so the actual chloroquine content is lowered. Mine says "Each tablet contains 250mg of chloroquine phosphate USP, equivalent to 150mg chloroquine base". I read through this thread and found info regarding the tablets.

In most cases, 250 mg tablets have an equivalence of 150 mg chloroquine base, and 500 mg tablets have an equivalence of 300 mg chloroquine base. Although the purity mentioned above is generally accurate, it would be best to verify the chloroquine base contained in the tablets of your choice in order to be able to properly calculate the exact dosage. Keep in mind if you decide to use the tablets, there are some inactive ingredients, which you may have to deal with, e.g., Camauba Wax, Colloidal Silicon Dioxide, Dibasic Calcium Phosphate, Hydroxypropyl Methylcellulose, Magnesium Stearate, Microcrystalline Cellulose, Polyethylene Glycol, Polysorbate 80, Pregelatinized Starch, Sodium Starch Glycolate, Stearic Acid, and Titanium Dioxide. And as mentioned earlier in this chapter there are occasions where some medicines are not in their pure form (100% pure), i.e., mixed with a substance called a 'carrier,' which should be noted on its label. If so its potency is reduced, and if not sure about the exact amount of medication needed, suggest contacting a more experienced aquarist for the way to resolve this situation".
I'd like to thank Humblefish for answering all my questions in my disease thread. The 5 wrasses are so far tolerating the CP well and eating. They have been in CP for 6 days now. Will update this thread and my own thread to let others know if fairy wrasses can tolerate CP.
