Medication in planted aquariums is a 2 step process. The first one is the hardest, correct diagnosis. Before you diagnose, make sure you do your research and be sure that the medication you are investing in is the right one for your fish. No point in finding out later on that the treatment doesn't seem to be working for you - that's because you have mis-diagnosed.
The second part is to ensure you medicate as quickly as possible. Don't skimp and choose economy post. You need Express Delivery so that you can begin treatment as soon as possible.
This option is available at the check out and all of our fish medication can be found here.
