I have been looking at all of the great pictures on the forum and have noticed that I never see powerheads and or pumps. Is this strategic angles or is there a good way to build live rock around them.
Some. Many people on here have Ecotech Vortechs, which are very low profile. I have three powerheads very visible in my tank, but my 55 gallon is rather narrow, and doesn't allow for much hiding.
