Buying Guide: How to Choose a 30 Gallon Saltwater Kit

  • Filtration: Look for a tank with integrated or rear filtration options. More robust filtration supports stable water quality for corals and fish.
  • Lighting: LED lighting with color control supports coral growth and vivid colors. Consider app control for customization.
  • Size and footprint: 28–32 gallon models fit most standard coral setups. Confirm dimensions align with your stand and cabinet space.
  • Glass quality: Low iron glass and beveled edges reduce distortion and provide a clearer view of livestock.
  • Maintenance: Check ease of access to media, filter socks, and pump maintenance. Quiet operation is preferable for living spaces.
  • Compatibility: Ensure the kit supports your intended livestock, coral types, and substrate. Some kits assume saltwater basics, while others are freshwater-first.
