I have a fluval 307 canister and have even told while carbon is great it's also not very beneficial besides odor reduction. I believe the recommended setup is phosphate pads,carbon, biomax media, then some other type of pads and foam filter. Any suggestions for what I should use other media to use besides carbon bags. I've seen recommendations for purigen or pot scrubbers. Also would they be placed in the same order replacing the carbon bags.
What is the purpose of polishing media...I don't get it maybe it's the name is it called polishing because it's the last media water goes through assuming it takes place of the phosphate pads.
