Features

• High quality all cast acrylic body construction.
   

• Down-flow media chamber design found superior to Reverse flow (fluidized reactors) in operation. Our design does not pulverize the media, which causes valve and line blockage which reverse flow reactors do. It does not grind the media into a fine powder but melts it instead.
   

• Designed for very low and efficient CO2 use.
   

• Clear cast acrylic reactor chamber.
   

• Unique dual inlet, with self filling PVC CO2 bubble counter & water inlet.
  You will never have to fill this counter. It will never dry out. Because it is PVC not acrylic it will not craze and crack over time.
   

• Commercial grade PVC/ Stainless check valve with quad ring seat and 1psi cracking pressure.
  If you ever replaced those cheap check valves that are always failing you can appreciate the difference a high quality unit will make.
   

• Free removable, refillable all PVC reverse flow reactor Cartridge for the tank's return.
  Can be used with Phosphate removing media or filled with calcium media for a second outlet stage reactor. Also available add-on to any other brand reactor $39.00
   

• Extra outlet Reactor Cartridges can be piggy backed. Available in 16" lengths $39.00
  Multiple units can be added for effluent water conditioning.
   

• Designed to use of any calcium media available without causing phosphate problems in your tank, when outlet reactor is filled half way with phosphate removing media.
   

• Oversized, Quiet & Strong external Pan World Water Pump for the best efficiency from your CO2 gas and a long service life not possible with reactors using powerhead type pumps.
   

• High quality unions on all fittings for easy service and cleaning
   

• Use of bulkhead fittings on the reactor body for long service life not possible with glued in PVC fittings.
   

• Includes all hoses and reliable non leaking Jaco fittings for water and CO2
  Jaco fittings unlike John guest fittings will not leak CO2 or water.
   

• PH probe holder accepts a PH monitor or better a PH controller will dispense your CO2 automatically "No bubbles to adjust"
