I’m in Canada and my 2 main options seem to be RedSea or Aqualantis. Aqualantis being the more affordable one. Anyone out there have an Aqualantis? I’m considering the aquaclear 150 in particular. Also, anyone know the difference between a freshwater and saltwater sump? From pics on their site, I just see a different baffle system w the saltwater sump having space for a skimmer.
