Thanks again! To clean sand I just used my metal scraper to swosh around the water just slightly above the sand, and get the any detrius back in the water column so hopefully it will get pushed back into the sump and to the skimmer, then I basically rake it.. (kinda like one of those bonsai garden thingys)
For the sand by the front edge of the glass. I use the back end of the scraper stab it down to the bottom of the tank, and just swosh the sand around by the edge of the glass, usually the only sand that gets algae growing on it is whats pressed against the glass so it will replace it self with clean looking sand since algae doesn't grow where it's dark. This will disrupt the sand bed a little...but the 1" of sand nex to the glass I disturb really isn't going to effect much.
