Hey everyone. Just recently got a reef octopus bh 100 from Craigslist. Super clean from the owner and I recently cleaned it with water and vinegar. I tried to see how it worked by hanging it from a bucket with water from the bath tub. It doesn't seem to produce a lot of bubbles at all. No micro bubbles at all. Just rather larger ones that I know for a fact won't skim anything. Does anyone have any advice and know how to work it? I tried looking up videos on YouTube but nothing comes up just reviews. Thanks everyone!
