Best Vacuum for Sand Bed

Hi All,



I was wondering if anyone has a good recommendation for a tank vacuum to get some surface debris (uneaten -by CUC- detritus, etc) up without causing a ton of sand to get sucked up. Also, are there vacs available that are easier to get into hard-to-reach places?



I know I can Google any product I want to know about, but I am looking for some feedback from experience, rather than some terrible marketer at an online sales store...



Thanks in advance.
