Sulphur Beads 1 litre

Sulphur Beads 1 litre


Sulphur Beads HQ. 1000mls (1.2kg).


100 gals/ 440l - 350gals/ 1100l per 1000mls, depending on reactor type used.


For Use With Freshwater and Marine Aquariums.


Very High Quality Sulphur beads. Small uniform shape and size.. allowing greater surface area of up to 100% over standard sulphur beads/ pearls

A slow water feed is used to flow through the sulphur beads and allows anaerobic bacteria to grow. The bacteria then feeds on nitrates and turns the nitrate into a gas.

When used within a Nitrate Reactor with Marine or High Ph freshwater systems, we recommend to use in conjunction with the calcium based media.... the sulphur will run at around ph6-6.5.. the calcium will buffer ph back to around ph7.8 - 8.2 depending on bio-load.

  • Instructions

    Allow 1 drip per 3 seconds till nitrate level reads near 5ppm through the reactor, this will usually take 1-2 weeks to complete. Increase flow to reactor to 1 drip per 2 seconds for a further 1-2 weeks or when the nitrate level again read 5ppm. Increase to 1 drip per second for 1-2 weeks or when the nitrate reads 0ppm and so on.


    Following this basis continue to increase the flow rate to its maximum flow of approx. 5 litres per hour or where the nitrate level ceases to drop

  • Instructions 2

    Wash Media’s

    1. Fill Nitrate reactor with Nitrate media (yellow beads)… placing the media on the bottom sponge.

    2. Push ‘O’ ring onto the downpipe... till 10 -20mm above the nitrate media. Then push media tray onto the 'O' ring., then add the blue sponge.

    Next fill reactor with calcium media, then add the final blue sponge and add the media tray above it.

    Fill reactor with aquarium water.

    Reseal lid... do not over tighten screws as this will cause the treads to stretch.

    3. Fit tubing to inlet (Far right elbow).

    4. Then run the rest of the piping to the aquarium/ sump and placing in the water where water is going to be 'drawn to the reactor. And cut to length.

    5. Then fit tubing to the outlet of the reactor (Top centre hosetail). (Top Offset Hosetail)

    6. Place Control Valve on the outlet and run outlet of reactor back to aquarium/ sump. Making sure the outlet piping sits approx. 30mm above the aquarium/ sump water. This aids the pump to draw in water.

    6a. Place Control Valve on degas chamber hose.

    7. Suck remaining air from the reactor by means of the outlet hose and degas valve… once air has gone, close the both valves.

    8. Add power to pump.

    9. Open outlet valve slowly till you get a drip rate is achieved.

    Residue air pockets maybe present in the reactor pipes, but this should dissipate overtime.

    10. If the pump struggles to draw in water from the sump, then place the inlet piping in the aquarium above. This will allow the water to gravity feed the kit rather than the pump pulling the water in... this also gives a better stable flow rate throught the kit. Please read write up in notes on inlet and outlet piping set up.

    11. Follow above flow rate instructions.

    12. Check the ph coming from the reactor periodically. If ph is running low, extra buffering maybe required. Run the effluent over coral sand etc to higher ph before entering the aquarium






    1. A Pre filter is recommended. This will collect and stop detritus from entering the reactor, spoiling the efficiency of the Nitrate reactor.

    2. The Nitrate reactor may produce nitrates for the initial set up period. We recommend you run the effluent from the reactor into a container rather than run into your system until the reactor begins to mature.

    3. Vertical Position of Reactor is required.


    Recommended: Inlet and out piping set up.

    Inlet Outlet

    Cabinet : Aquarium to Aquarium

    Sump : Aquarium to Sump
