I wanted to use Prazipro on piranha and know it is safe but wanted some clarification on how to use. I have a 75gallon tank so I will use the right dosage. It looks like you do a large water change and then introduce the meds. The questions I have are:
1) do you only dose on the first day?
2) do you need to use carbon after the 7 days are up or does the meds go away?
