Actual flow requirements for red ogo and ulva?

[living_tribunal]

For the last two years or so I've been trying to find an ultra low powered power head for my 10-12G fuge to get some more flow. This has proven to be a losing battle.

I recently switched up the macro algae in my fuge to red ogo/ulva and was curious to see what the true flow requirements are from those with experience. I know many have no problems growing chaeto with little to no flow but can the same be said for red ogo/ulva?

Furthermore, what is the best ultra low powered power head for a smaller 12G fuge? I've tried the tunze 6015 nano stream and the hydor koralia nano 240. While the 240 is alright, it's still a little intense for such a small area.

For a pump you could try the Jebao OW10. I have 2ea in my 20g rock nem tank set on the lowest settings. Thye cycle on and off (1hr opposite times) controlled by my apex

The Aqamai KPS by Hydor, controllable and as small as an egg. KPs | Movement pump - Aqamai

Requirement? Hardly any flow honestly. Macroalgae can grow in any flow level IME.

There is no exact flow requirements but they should not be stagnant.
