Thank you.

Hi bro, a 4 x 2 x 2 should be around 450L, and your pump maybe after head-loss would be maybe 3000? so that is around 6 times roll over per hour which is ok. However you probably need to take a look at your fishes if they are able to handle the flow rate, if u feel it is too fast for them, u could always swap over to a lower flow rate pump, alternatively u could install a valve from day 1. hope this helps
