Ugh, im getting pretty frustrated with my BM5 also. Its very eratic and does whatever it wants. When i got it i did a vinegar bath overnight put it in the sump on lowest water level, it eventually broke in and was working great i had to keep adjusting the water level higher and higher over 6months. It was at highest water level and not skimming. I pulled it all apart toothbrush ect, then a vinegar bath. I put it back in the sump and it took 3 days to start producing skim again.

I would like to hear from someone who has had good success with a BM.

Do you have a filter sock before the skimmer?
