Why do you have to remove carbon from filters when adding medications to your aquarium?
Is it because the carbon filters out the medication, or does the medication ruin the carbon in the filter, or what?
Thanks
Because the carbon will remove the medication from the water as it is filtered and so it will make it ineffective for treating the fishes’ disease. The fish will get hardly any of the meds because the charcoal will filter it out of the water. So, you must take the carbon out of the filter so that it continues to circulate and the fish will get the full effect of the medication in the water.
