AK Culturi-S Pro
Compact, smart culturing made complete.
Culturing microalgae requires consistent lighting, sterile conditions, and reliable aeration. The AK Culturi-S Pro brings it all together in one compact all-in-one system, with a smart full spectrum light and integrated air pump included.
Integrated Air Pump
Includes a dedicated air pump for reliable circulation and aeration, helping maintain consistent culture performance.
1L Vessel
Produces enough phytoplankton weekly to support most reef tanks, even those with higher biodiversity demands.
Smart Integration
Includes a full spectrum RGB+CCT smart light with app control and support for Google Home and Alexa.
Replaceable Parts
All key parts are replaceable, from vessels and tubing to lids and fittings, so you are never stuck replacing the whole unit.
AIO Convenience
Unlike pieced-together DIY setups, the Culturi-S Pro includes the core equipment you need in one refined, compact system.
Sealed System
Pressure-release valve and precision glass tubing help maintain sterile culturing conditions with minimal contamination risk.
Why buy it?
Here's a few reasons that makes the AK Culturi-S Pro bang worth it's buck, over typical DIY setups...
Everything in One Kit
Buying the AK Culturi-S Pro saves you time going from shop to shop, researching lighting, air pumps, fittings, and containers that actually work together. Everything you need to start and maintain a healthy phytoplankton culture is already included, tested, and compatible.
Hygienic Glass Construction
Glass components are easy to clean and maintain, unlike typical setups that use black tubing and porous plastic containers where bacteria easily accumulate.

It's likely more than enough...
For most aquarists, a 1L (0.26 gal) culture is plenty for weekly use. Many even end up with extra. There’s no need to grow more than your tank requires; it’ll only take up fridge space or end up going to waste.
Made in the U.S.A
That's right! The AK Culturi-S Pro is proudly made, assembled, packaged, and shipped right here in Texas.
What's in the box
Everything you need to get started
AK Culturi-S Pro Light & Air Pump Unit
Combining a smart RGB lighting system and built-in air pump in one convenient all-in-one unit, it delivers customisable illumination, constant aeration, and reliable circulation to help keep cultures stable, healthy, and growing at their best.
1L Glass Culture Vessel
More than enough for most reef systems. Add a second vessel and rotate weekly, connect your doser to the previous culture for a steady, automated supply using a peristaltic pump.
Culturi Vessel Lid
Custom-designed for a thick, airtight fit, the branded AK lid looks great and comes with all necessary seals and a pressure-release valve to protect your cultures from foreign airborne contaminants.
Glass Rigid Tubing & Pipe Cleaner
Easy to clean glass rigid tubing makes sterilisation a breeze
3/16" Airline Tubing (5ft~)
All necessary connections
Microfibre Cleaning Cloth & Pipette
Simple necessary accessories for every culture enthusiast, the cloth for cleaning the glass in-between cultures, and the pipette for precise dosing of Guillard's F/2 fertiliser. (An appropriate sized syringe may be provided in place of pipettes depending on availability.)
Check & Gate Valves
Easily prevent water flowing back into pumps and regulate air flow precisely with these included extras.
Detailed Instructions
A quick start guide to throw you straight into a successful culture, complete with QR codes to take you to useful resources.
Phytoplankton feeds everything
Phytoplankton gut loads filter feeders like copepods, rotifers, and other zooplankton giving them a higher nutritional value when consumed by your fish and/or corals. Phytoplankton is also responsible for 51%~ of the worlds oxygen.
Frequently Asked Questions
Q. What's the total fill volume of the AK Culturi-S Pro?
A. The vessel features a max fill line which is positioned exactly at the 1 liter mark, so the total volume of water possible is 1 liter (or 0.26 gallons)
Q. Is the lighting spectrum adjustable?
A. Yes. Use the app to adjust between 3000–6500 K white light or select RGB modes. You are also able to modify the brightness, which can help refine temperatures and lower lighting intensities can be required for more sensitive strains.
Q. Is any starter culture or fertiliser included as standard?
A. No, unfortunately we are unable to provide starter culture or fertilizer at this time.
Q. Why did I receive multiple tracking numbers?
A. This is usually because your order contained a combination of items, which had to be fulfilled and shipped from multiple locations. No additional fee is added to your order, we cover the price of the additional shipping in these occurrences.
Q. Is the AK Culturi-S Pro 3D printed?
A. Yes, this model of the Culturi marks our first step into a new wave of innovation. We have no plans to move away from 3D printing, as it gives us the flexibility to evolve the design over time, respond quickly to what works best, and produce complex geometries that are difficult or impossible to achieve with injection moulding.
Q. What's the point of RGB?
A. It’s what we call “surplus functionality”. That said, if you’re interested in experimenting, the Culturi can also be used to kick-start macroalgae like Dragon’s Breath or Caulerpa, which benefit from the red spectrum. For phytoplankton, though, white light remains the gold standard for optimal photosynthesis. We've chosen this light for it's ability to handle on/off scheduling, brightness adjustments, nothing more. Besides, a little disco-mode is fun when harvesting, right?
Where does it ship from?
A. We manufacture and ship directly from Texas, USA
