Hey guys I have a Waterbox peninsula 25 mini. I just recently purchased a mp10 and unsure where best placement is. Where I have it currently is causing microbibbles.
Where you have it actually looks pretty good. Bubbles from it being directed at the overflow or drawing from the surface? If the latter, you have that pump blasting. I would actually have it even closer to the surface (like right to the bottom of the sticky holder) to create a "roll" in the tank, but the speed has to be adjusted to prevent sucking from the surface. I'd probably have it mounted 180 on the opposite side. Of course this all depends on what you are keeping and your flow needs.
I actually turned flow down. The highest it goes is 50 percent on reef crest. Reef crest seems to be the option people like. My tank was clear before adding the mp10 so trying to figure out what to do to clear it up. Everything is still happy just looks aittle cloudy due to bubbles. The pump is not sucking in any air.
