Last night while doing a regular water change, I decided to vacuum the sump and rinse the pumps. We have no filter media in the sump, bare bones, no lights either. There was a considerable amount of muck on the bottom of the sump. After completing the change I thought about what I had done. Did I remove an essential amount of bacteria or other organisms from the system or is this standard good housekeeping practice?
Also we are trying a product called Algone. Anyone have any experience with it? Can it be used with Auquamarine nitrate reducer?
Thanks,
