I was wondering if peat will remove any medication from the water..such as any sulphur drug or any of the parisite medications...I have made some great peat filters for my blackwater fish out of 4 inch PVC pipe..each filter holds 2 pounds of peat..you can use just about any media you want in them also...sponge, carbon, whatever you want..but I did not know if peat absorbs any type of medications...
