I had the multi on my first tank a 66g I wouldn't put it on anything much bigger. At the time it was overpriced IMO, I like the Ocean Runner pumps but it has limited adjust-ability and you might have micro bubble issues. With the drop in price of Euroreefs like the RS80 you could do a lot better for the money.
If you do use it for a HOB skimmer tap a drain into the collection cup to a waste container because it will overflow at some point.
Or better set up a small sump (you will eventually anyway
) with an overflow box if your tank isn't drilled, a small return pump and a Euroreef.
The Tunze might be a better option but I have no experience with them.
