skimmers are prolly the most important item on a SW system. this is the one item i would not skimp on. the skilter is just trying to do to much so it is not very efficient. the visi is just a nightmare to run. it is heavily based on tank water level. if the tank water level changes even slightly, due to evaporation, than the skimmer will not work as effectively.
i would really look at a CPR backpack or Aquac Ramora.
take special note to make sure that it is not to tall to work on you tank.
does CSS make a
HOB skimmer anybody?
