I too have the "F" effect from the from an installation very similar to what Mr. Lusk described. Pea gravel was used instead of crushed rock. I wish the grass in my entire yard was as nice as the leach bed. We are careful of what we put down the drain for both septic system and pond health. No harsh cleaning chemicals, grease or cooking oil and we avoid "antibacterial" products that go down the drain as well. I'm not sure if the antibacterial products harm the break-down process but it sure seems like they could.
