A50 Light Kit

A50 Light Kit


Algae Reactor A50 (50gals/ 200l).

For removal of phosphate and nitrate from Marine and Freshwater systems.

This kit uses the PO4 150 reactor as the basis for this kit.

The waterproof leds are to be wrapped around the reactor body and held in place with 3 x cables ties (supplied).

Sponges can be removed and just the media trays can be used. Algae can then be tired to the media trays with cable ties etc.

This makes a cheap but effective way to help remove phosphate and nitrate from your system... with a little help of some chaeto (algae).

Designed as a free-standing, in sump or as a hang-on reactor.
Please state on purchase if you would like a hang-on bracket fitted... as the reactor will be sent without a bracket otherwise.

Kit includes:

Algae (PO4 150) reactor, 12v LED strip (1.5m), control valve, 12v adapter and 3 x cable ties.

The LEDs supplied will be a Red /Blue Spectrum.

Leds should not be submerged in water.

Pump Requirement: 500lph

Algae Capacity: 1.5l ( Algae purchased separately ) .

Power Consumption : 21w

Dimensions (mm):

Height: 400

Footprint: 130

Column Dia: 90

Hosetail Dia:12

  • Instructions

    1. Locate the power supply, power cable, and LED array. Plug the male end of the power supply into the female on the LED holder.


    2. Plug in and ensure that the power supply is not close to an open water source and is protected from any water spray.


    3. Wrap Led strip around the reactor chamber, laying it evenly top to bottom around the chamber. Secure in position using cable ties supplied.

    Add power. Check that the LEDs light work correctly. Once checked, turn off power


    4. Plumb your reactor into a pump, adding control valve inline.


    5. Open the reactor and add Chaetomorpha algae... a handfull or two will be fine.


    6. Offer lid, checking no debris or algae strands are sitting on the flange gasket.


    7. Tighten nuts, remembering not to over tighten as this will cause stripping of the thread.


    8. Connect piping to the inlet and output fitting on the lid. Run piping to the supply pump. Remember to add conrol valve inline from the supply pump. Ensure that the plumbing is secure and that there are no blockages.


    9. Close valve and turn on the flow to reactor and open slowy and check for leaks.

    Run a steady flow of around 500lph or to suit your requirements.


    10. Add power to the LEDs.


    The reactor should be on a "reverse daylight" schedule from that of your display aquarium. It is best if your reactor turns on 1 hour before the display tank lights turn off, and remains on 1 hour after they turn off. Be sure to plug the power supply into the timer or appropriate socket of your controller.


    1. Turn off the power to the feed pump and light.


    2. Remove the lid and light assembly and empty the Chaetomorpha into a container, add to this enough tank water to submerge the algae. Rinse the algae in the bucket by plunging it up and down. This will dislodge the bacterial film growing on the algae surface. Discard the water from the bucket and remove up to a third of the algae and dispose of it. Stretch the remaining algae so that when it is placed back in the reactor it fills the tube as much as possible.


    3. Refit lid and reconnect the pump and light and turn back on. It is recommended minimum of 8hrs of darkness for the algae reactor... 24 hour lighting will stress the algae and not increase the growth rate.


    The nitrogen supplement and Iron/Manganese solution can be used in this system.

    The Iron Manganese solution should be dosed on a regular basis. Iron is not easily tested for and will precipitate out rapidly, but it is necessary for the health of your algae growth.

    We recommend 1 drop per 40 litres daily.
