Circulation pump recommendations

Hello I’m looking at adding more flow to my tank 120cm in length to help circulate Fertilizer and CO2 any recommendations please

I’ve had good experience with the Sicce nano voyager, either 1000lph or 2000lph. Personally I prefer several smaller pumps than one large one. I’ve also found Tunze pumps to be excellent and very quiet for their output.

Maxspect Gyre, not cheap but packs lots of output and you can configure the output on a schedule
