+1 Instar! Introduction of 02 to the pond bottom where the organic muck resides allows for aerobic bacteria to exist, which is much more efficient at reducing the matter than anaerobic bacteria. I'd consider saving your money on the muck reducer stuff, keep the aeration going, and allow mother nature to slowly knock it back. Keep records, I'll bet you see a steady decline. Hope this helps.
