Hello everyone, I am few weeks old in this domain. I have a three feet wide tank which holds 45gallon/120litres. And I have around 50 tetra neons and four german red guppies. The filter I am using says 650l/hour...guess this is what it does in an hour..is this filter optimum? I never see the tank water crystal clear though..would a Powerful filter do the job? Or an external flter is better? Please suggest
