I treated my pond with Stop Blanketweed but I now need to treat my fish with a medication. How long should I wait before I use another chemical?

Our advice is to leave it 7 days after using one treatment before you use another treatment. And also carry out a partial water change if needed, if the medication may react with the first. Please note, in the case of the Stop Blanketweed, for this treatment to be at its most effective the advice is to use that once a week for 3 - 4 weeks. Therefore interrupting the Stop Blanketweed dosing application will impact on its performance.
