I bought a used MRC MR-1 skimmer and after 24 hours it still isn't producing any foam. The instructions said to wait 24 hours, but I know that sometimes it can take several days to 'break in' the skimmer. Does this several day break in time include used skimmers? Should I just wait a day or two before panicking? The guy who had it before me was using a Mag 18, but I picked up a Mag 12 for it which is one of the pumps MRC suggests using with it.
