RSM130

[michaelis88]

I have the rsm 250 one. I do use a power head pointing the back of my live rock so make no dead area, and it's downward. Don't get shrimp as they don't really work much on the bottom, just stay hiding in the rock usually. Maybe nasari snails or sand sift star, something that will dig into Ur sand and consume what so ever.
Siphons is good idea, but with sugar sand I have, it will pull the sand out as well. By the end of the year I gotta buy a new pack of sand.
The best way if u are starting a new tank, have no sand is the best idea. Makes no dead spot, no food or anything left over in the sand. And it's easier to vacuum!
