vacuuming gravel

  1. General Reef Discussion
    Saw a new product by EHEIM they have a battery powered vacuum and I just wondering on anyone's thoughts or input on these devices. I know that EHEIM makes great pumps (also pricy). My thoughts on it where if I see detritus built up in the sand I could remove even if its not the weekly water...
  2. The THINK Tank
    Should I or shouldn't I? I do but I am told I shouldn't. Debate please.
