I am treating velvet in my fish only tank with chloroquine diphosphate and have done some research over the internet. There are several contradictory informations regarding to the dosage and can someone help me clarify?

Overall the recommanded dosage is between 40-80mg/gl but what I am confused about is the need for repeat dosage of 40mg/gl weekly for 3 more times? Some said it is necessary because CP act the same as copper will become absorbed by the substract or somehow broken down by the bacteria in the tank and repeat dosage is needed. Some said it is very stable and substract will not have any impact on the dosage.

Have anyone had any experience on CP especially dosing to FOWLR display tank? Also many says CP is sensitive to light and all light must be switched off and some says it is only sensitive as powder and once in solution the light will not affect it too much. Which is true? I am talking about moderate led light not strong metal halide lighting.
