Without creating a large debate let me ask a simple question. I purchases some active carbon at my LFS and tonight was going to add it. I noticed it says it contains less than 3 parts per billion phosphates.
Should I throw it away and buy some Kent marine phosphate free, or use this until its gone? I like to avoid problems before they start. Sadly I already opened the carbon and taking it back is an issue. Thanks
