Sorry I have a few questions to get it off my rocks i have to scrape it with a knife right? But all my rocks have tons of coral on them so how would I do that. Secondly instead of rinsing the sand, can I just get new sand and rinse that before I start the rip.If you truly read the thread you see that cleaning it isn't a restart anymore than doing a water change is a restart
When you start a reef, you use bottle bacteria. We never did use any, it's just tank cleaning.
The thread answers every possible question including how well it works, because you can click on any entrant and see their follow up posts on the tank.
