Random Flow Generator (RFG) by REEF-PRINT

  • Sale
  • Regular price £9.95
Tax included. Shipping calculated at checkout.


Key Features:
  • Specifically re-designed and tested by a team of fully qualified Aerospace Engineers (see below for more detail)

  • Revised design has been simulated using Computational Fluid Dynamics (CFD) technology to maximise water flow velocity and randomness

  • Snaps directly onto standard Loc-Lines – ¼”, ½” or ¾”

  • If you require a straight pipe adapter, as your tank does not use loc-lines, then please choose the straight pipe adapter option and message us your existing pipe OUTER DIAMETER (in mm), and we will include an adapter which will slide on over your existing pipework

  • Made from 100% reef-safe PETG Plastic (FDA & RoHS Approved)

  • Quality guarantee: We firmly believe the quality of our products will speak for themselves. We have personally witnessed some very poorly made products, and hence we decided to re-design products and improve the quality of the manufactured products ourselves and set up REEF-PRINT. We would never sell any products that we wouldn't use ourselves.

Why the redesign?

In our CFD simulations, existing designs (specifically the internal fins) reduced the output flow too much with preference of turbulence (i.e. random flow), despite having an educator nozzle built in, which should have in theory increased flow by around 5 times. We have also found that some designs which have been distributed (specifically noticeable due to its shorter length) do not randomise flow very much at all.

Reef-Print’s revised and improved flow nozzles creates a fine balance between improving flow performance with the educator nozzle and providing optimal random flow through the redesigned internal fins. 

Why do you need one?

  • Random Flow – Random Flow Generators does exactly what it says on the tin! It provides random flow patterns from your return pump outlet, mimicking the natural sea currents

  • Flow booster – the built in educator uses the variations in pressure to suck in additional water surrounding the RFG, and increases flow volume by around 5 times!

  • Your corals will love you for it – because you will no longer be blasting the corals face-on!


What size do I need?

  • There are several guides available on Google to help you determine what is the correct Loc-Line size you require and we really do recommend that you look up the sizing guides online before ordering.

  • If you're not sure what size you need, send us a message and we can help.
