Coast To Coast Overflow

If you’re looking for a full length overflow to run along the back of your reef tank then it’s a good idea to go for a coast to coast overflow. These are 4 sided and they have no back panel. There are a few advantages to a coast to coast overflow design:

  • they’re safer – a fish could swim into a coast to coast overflow and not be hurt
  • they can improve the performance of skimmers as they do a lot of the skimming for you
  • it can act as a temporary cooling off tank

If you want a coast to coast overflow then you’ll usually need a custom build, however the product below could be used.
