• Built-in 10 W LED grow light — runs continuously to drive fast microalgae division without a separate aquarium light or windowsill.
• 5-litre acrylic culture vessel — small enough for a fish room shelf, large enough to feed a moderately stocked reef or a copepod culture on rotation.
• Dual hose connection (2 x 4/6 mm) — one line for aeration, one for CO2 dosing where you're running enriched cultures.
• Dosing-clamp hose included — meter a slow, continuous harvest into the display or refugium instead of dumping the whole culture at once.
• pH probe holder in the lid — monitor culture health without opening the vessel.
• Runs on around 88 kWh a year — the LED is designed to stay lit 24/7, and at 10 W that's cheap enough to leave running continuously.

If you're feeding one reef tank a supplementary dose of phytoplankton a few times a week, the II is the right size. If you're running continuous culture to feed several systems, or breeding copepods and rotifers at volume, the PRO's tenfold capacity is the one that keeps up.

• Plankton Light Reactor II vessel with integrated 10 W LED lid
• Dosing-clamp hose
• pH probe holder (probe not included)

• Air pump — Aqua Medic recommends a Mistral 100 or larger to aerate the culture; this isn't supplied
• Starter phytoplankton culture
• Fertiliser or culture medium

Suitable for: hobbyists culturing phytoplankton to feed corals, clams, feather dusters and other filter feeders; copepod and rotifer culture that needs a steady green-water feed; refugium dosing.

Not suitable for: mass production for a commercial-scale operation — step up to the PRO; running without an external air pump, which the reactor needs to keep the culture in suspension and gas-exchanged.

Rinse the vessel and lid between culture batches to stop old algae fouling the next one. Wipe the inside of the acrylic occasionally so light output doesn't drop as it fouls.

Mains-powered — keep the transformer and connections away from splashes and standing water, and don't submerge the lid electronics.

• An air pump such as a Mistral 100 or larger, to keep the culture aerated and mixed
• A dosing pump, to automate the metered feed this reactor is built to support
• Copepod or phytoplankton starter cultures, to seed the vessel

Do I need an air pump to run this?

Yes. The reactor doesn't include one — Aqua Medic specifies a Mistral 100 or larger to keep the culture aerated and in suspension.

Can I run freshwater infusoria in this as well as marine phytoplankton?

Yes, the vessel and light work for either saltwater microalgae or freshwater culture — only the starter culture you add changes.

How fast does the culture grow?

Aqua Medic states the algae mass can quadruple in 24 hours under good light, aeration and nutrient conditions, though real-world speed depends on your starter culture and how consistently you feed it.

Does it dose the tank automatically?

No — the included dosing-clamp hose lets you meter a manual or pump-assisted feed; it isn't a self-contained doser.
