hey i just got a 72 gallon bowfront tank and im getting piranhas for it and i have to filter for it either a aqueon 75 which is rated at 400gph and or i can put a emperor 400b which is also 400 gph , which 1 is better to use overall, most quiet, most reliable, and does the best cleaning, i like em both but idk which to use thank u,
also should i just ditch em both and buy a ac70
