Media in dry sump area?

[Ping]

Alot to digest. Is Rubble deep enough to have anaerobic bacteria. I remember the post on cell-pore. Don, how long have you had yours in the sump. Any idea how long before is "seeds" with benificial bacteria.

Oh, and thank you all for the info. I enjoy reading the thought provoking debates.

Ping...its been a few months now. I can't say for sure on how long it takes the cell-pore to colonize, maybe Gary can help with that. One thing is certain...my nitrates are on a slow decline, the problem is that I am doing so many different things I am not sure which one is working the best.
