I have a reddevil and a 10 inch pike cichlid in a 75 gallon.On the tank is two penguin 350 filters and 1 powerhead pumping 300gph .Is this a good set up or should i add more equipment.
You have plenty of filtration. Keep an eye on the filters for the Penguins
as they do get plugged on occasions with debris. Just alternate cleaning/ rinsing them out when you gravel vac. the tank.
