Simple, reliable, low-maintenance. This Fish Farm can automatically remove fish waste every few hours, day and night, maintaining excellent water quality. You don't have any fish waste to handle or waste water to haul. In the basic system the filter is washed by opening a valve for 20 seconds. The Pulse Auto Control Panel can be added at any time to automate filter cleaning and fish feeding and is recommended for heavy fish and feed loading. The basic system supports up to 50 lbs of fed fish. The Precision AutoFeeder coupled with the Auto Control Panel make a complete, self-sustaining life support system (five days at heavy feeding). A single energy-efficient, ultra-quiet air pump recirculates the water, delivers air to the diffuser and cleans the filter. The innovative Pulse BioClarifier gently settles out fish waste, captures suspended particles and acts as a biofilter. Select the automatic Pulse wash cycle using two dials–one for time on, one for time off. It's simple! The 400-gallon tank selfcleans through a center drain and is equipped with a float valve that maintains tank water level. Request the UV sterilizer to keep water and filter clear of algae and to reduce fish pathogens. The FIAP Fish Farm Maxi comes with a sturdy dome frame for hanging the Precision AutoFeeder and for supporting the net cover (included). Secure a tarp to the frame to exclude light or airborne pollutants. Components assemble in about 1 hour. Note: All plumbing will be underground w/out stands. Operate several FIAP Fish Farms Maxi with one Pulse controller and large air pump.
