I have a medium mush koi pond about 2000gals with 3 koi and about 25 goldfish I want to use an aquaponics system to replace the bog filter… few questions with startup new system: Do you want the water flowing over the roots all day / night? Only the roots in the water? How to keep the leaves from drooping down? What system is best to use? Any other helpful advice is greatly appreciated! submitted by /u/Bjbttmbird
