Bros,

I am buying an external filter system Jebao 1000L/hr for my 3ft tank.

As most bros recommend, we need to have minimal agitation to the surface, I am think of submerging the outlet (using a rainbar) just 2cm from the surface of the water on the left side of tank. My intake is on the right. Does this provide good circulation or too much circulation due to the rain bar?

Thanks.
