Eco Complete is man made from natural products. If you know how marketers think then you can decipher what they 'claim'. Its all natural but not naturally occurring. This is why they have had big issues with bad batches and leaching nutrients into the water column.
Seachem has released Flourite Black, Flourite Dark and Flourite Black Sand. This is a mined natural product. Look for it to show up in the online dealers any time now.
Carbon will release loads of phosphate into the water column and eventually will foul the water after it has absorbed all the nasties it scavenges.
