Hi

Looking for some advice on which way to point the water return diverters? I have a fluval 406 ad in the tank are 6x zebra danios, 6x white cloud minnow, 12 neon tetras and 6 harlequin rasbora.

The flow is strong but every time i turn it down the danios and minnow run for the air pump ! Most of the time these two just hand by the return pipe. The harelquin love the air pump and think it is an escalator!



Help! Advice on understanding the best way to setup the water flow diveters and on flow? what are the signs?
 
Angle them where they're aimed towards the top of the water creating breaks in the water surface allowing for gas exchange..
