Hey guys so I've had my IM50 set up for about 6 months and wanted to see what you guys are using to clean the rear chamber of all the crap? I am using the caddys not the socks and I'm just having a hell of an issue with nitrates and phosphates. I don't know what to use for Skimmer cause nothing fits. I'm getting this air pump one that's smaller off amazon today but I'm not putting a lot of hope in that. What do you guys do to just help filtration and nutrition export?
