filtration for cichlid 40 gallon

[large_cichlids]

what should i use for filtration on a 40 gallon cichlid tank.I was thinking a aquaclear 500 but what do u guys think

 

[REDKID!!!]

depends on what fish your getting but a 500 would do it

what are the planned inhabitants?

I plan to use it as a redterror growout tank and then get a 125 next year. .Im only putting one fish in there tho.

that would be ok but you dont want to breed them once it gets moved into the 125?
