Hi,
I understand that a higher flow rate in a tank is beneficial as it keeps the dirt suspended for longer and therefore gives the filter more opportunty to pick it up.
Does the flow also have any effect on bacterial levels, or is that largely determined by filter material and size of filter? (I know that it will also depend on the condition/maturity of the filter)
As always thanks for any replies posted
(The reason for my question is that I have a fluval 4+ internal power filter, with standard foam media. [the tank is 160L, currently with 75W lighting by the way]. The fluval is currently turned to its lowest flow rate and I wonder if cranking it up will help and in what ways.)
