I built a 3 tiered system because I'm tired of picking worms out of the castings.The worms don't seem to travel to the new food. Well they do, but there are plenty of worms left behind that seem perfectly content to live in the bottom tier with nothing but castings. I'm also worried about oxygen levels in this thing. Not sure how many worms are in here but they eat a 5 gallon bucket worth of food in about 2 weeks.Thoughts on this design? Ideas for how to get the worms to travel?Photos show from…See More
I'm new to Aquaponics and going to build my first system in the next couple of weeks. I have a question though. What size pumps should I get? I have three IBC totes I'm going to set up for raising the fish. I plan on using an airator in the system. Can someone suggest what size pumps I should use for pumping the water and for the airator? How many GPH and what horsepower? Any help will be greatly appreciated!
