clean what? Unlike fw, we do not actually clean our tanks. We just let the tank clean itself, occasionally clenaing he glass and maybe the rock. To clean the fork, we just use a turkey baster and squirt the junk off and let teh tank and skimmer do the rest. for the glass, we let teh snails dclean this, andmaybe occassionally scrape it witha razor blade or scraper.
Other than that, all we do is water changes(only partials, like maybe 10%)
