Hi. I know that question was asked million times. After few years in the hobby I changed my regimen. I know this topic is controversial, so many people against and as many are with me. Every fish I will buy from now will go thru Prazipro and Cupramine treatment. Doesn't matter if looks healthy or not. My question is. What is the proper level of Cupramine? 0.5? Lot of people saying it can be lower like 0.3 and will be easier on fish.... And second question is How Long should I keep that level. Please let me know. There is so many different opinions but I trust you guys. You were always spot on.Thank you.
