AquaponicHerb Reviewed by AquaponicHerb on . The Suck-it Bucket (NEW) Ok. The way this thing works: The bucket has a pot inside of it with 5/8inch perforations on the bottom only; it fits a perfect seal inside the bucket. See first picture.... Super oxygenated venturi-driven water trickles in from the top through 1/2" tube when my timer kicks in. A venturi is better than an airstone for many reasons, we can get to that later. Also the oxygenated water has to feed in from the top in order for the process to work properly. This creates pressurization inside Rating: 5
