MacroAlgae reactor flow rate

[BlazinNano]

Making a macroalgae reactor but the question I have is how much flow should go through it? Do I need to go with slow like 50-75 gph or med like 175-225 gph?

Depends a bit on the macro. I'd start out with the slower flow.

you need to go as high as possible. 300+gph
