Lately I've been sidetracked with life and neglecting my aquariums routines. How do I clean those hard to reach places in your tanks? You know, those places that don't get the highest water flow. My Sps are blocking straight shots to the sand so traditional siphoning won't work. Also, some of the rocks have that dusty, silty looking covering. Any tips or tricks would be greatly appreciated.
A power head went out so once that is replaced flow will be better.
