For gold fish in fully stockedtank would two water filters be better one internal and other external
Someone told me once in a normal tank you should have 6x the gallons of your tank in gph. For example my aqueon quietflow 30 is rated at 200gph and my aquatech 10-20 is rated at 120gph. My tank is 36 gallons and 36x6 is 216 while my combined gph is 320.
I'm not sure if the person who said the 6x gph thing was correct, but if he was then you'd want even more in a goldfish tank. I hope someone comes in and tells me whether I'm right or I'm way way off
