Fish Holding Tank

Fish Holding Tank - Water Bath

Stores your fish and let them

acclimate, undisturbed, to your laboratory conditions

A peaceful, optimal environment

  • A very quiet system!
  • Wide temperature range (2-30°C).
  • A swift current (4 cm/sec) reduces aggressive behavior in fish (adjustable).
  • Tank is divided into two sections with removable screen insert
  • Clear lid, exposing fish to ambient photoperiod
  • Air stone for additional aeration (if required)
  • Makes a great water bath for static-type experiments!

Green technology!

  • Uses little water: up to 99.9% of water flow is recycled
  • Efficient pump and chilling system
  • Insulated tank

Requires little maintenance

  • No siphoning needed; a swift water flow flushes debris to a novel sediment trap.
  • Easy-access, five-stage water filtration: solid removal pad with activated carbon, carbonate buffer, biofiltration, efficient CO2 degassing by propeller pump
  • Biofilter comes pre-coated with active nitrifying bacteria (unique). This significantly cuts back ammonia peak when the unit is initially filled with animals.
  • Water pipes can be dismantled for cleaning and disinfecting; ceramic biofilter autoclavable.
  • Tank on a high-strength industrial grade fiberglass and plastic stand, with built-in Microban® antimicrobial protection.
  • Heat exchanger is in seawater-resistant titanium.
