Hygger 951 settings you are using

[cable guy]

So I have a nano tank 20 gallons, 24inch long , I have my return pump that’s towards right back and facing front glass slightly downward flow, and I have the wave maker on the left side of the tank slightly towards more of the back.. my main question is anyone that has these huggers 951 what is your setting you are using, are you like 100% flow during the day and dropping at night to 50%? And what mode are you using? Wave? Random?

It really depends on the tank and rock layout. Everyone's system will be different as far as flow is concerned. One may run theirs higher, while another may need to be lower. I'd just watch your corals and make sure they aren't being blasted around.
