I bought a aoctopus extreme 200 I know that they are supposed to take a few weeks to break in I built a stand for it over the weekend and it is in 8" of water on my 150 gal with a 40 gal sump. I don't think that it is producing very muchonly about an 1/8 of an inch of water from 7:00pm- 930am. I have heard of doing a mesh mod on the pump, but don't want to mess things up does anyone have a good link to get me started so that it gets done correctly if I do it. Or wouldn't you suggest doing this yet...
