good morning, thank you so much for your valued reply. i will research this product and see if it is available in South Africa or if i can find a similar product with the same active ingredient. Tomorrow will be 48hrs after his last does of Kanaplex, so i will be able to add a different medication. Please advise if i must do a partial water change change. his QT is 80cm x 30cm x 30xm and i have an internal filter with spray bar and air stone. temp is 27* and water tested today N02 -0 / NO3- 25 - gh ph kh are good and cl2 -0 ( i use sera test strips) Amonia?
Once again thank you for your advise
I would always do a water change prior to switching medications. If you have activated carbon, then use that as well for at least 24 hours prior to using new medication, and then removing it.
