  1. I was so thrilled with last winter's small experiment with two IBC, 60 small tilapia and 30 square feet of grow beds that I took a big jump, built a 20x40 insulated building and maybe the jump was too big because I don't have any nitrates yet. I have the two IBC, 20 small fish, two small sumps with fiber media in series (20 gallons each) with no grow beds but six 4x8 foot rafts, each with about 60 gallons of water. I just added 15 square feet of media/growbed. All I have growing in the first of the 6 rafts is about 50 lettuce seedlings. They aren't growing. Ammonia is about .8, nitrite 0, nitrate 20, pH 7.5, temperature 80F, lots of aeration. Any ideas? I thought I might isolate the one IBC to circulate with the new gravel growbed, add household ammonium and see if I can encourage bacteria to get to work for me. The gravel bed sits atop that IBC and is flood and drain. I can keep the rest of the system from getting any of the enriched/ammoniated water until I see if it begins to cycle with the addition of the growbed gravel. There are no fish in that IBC; they are all in the other IBC and either or both feed back to the sumps with a solids lifting overflow. Is the problem that I have such a huge ratio of water to the number of small fish?
  2. Hello! My name is Niall and I am interested in starting my own small scale aquaponics system. I first learned about aquaponics when I read about the Aqualibrium system. The system looks great, but is pricey, and seems as though it doesn't give you the option to expand. So my intention is to: Build a small system, roughly the same size Aqualibirum. Their grow bed is 1.5ft x 1.5ft, as is their fish tank. Source materials as cheap as possible, even free if I have to. Any tips or advice on sourcing or salvaging equipment is welcome. Seek advice on climate control. I intend to locate my system in my bathroom, located on an exterior wall. The pipes freeze in the winter and there's no air-con for the 30 degree summers. Seek advice on grow bed material, I am aware of expandable clay, I am also somewhat knowledgeable on composting. Seek advice on cycling, I have the time and patience to run trial and error. However I don't not have the funds to afford expensive tester kits, or replacement fish. Connect with other Aquaponics community members locally. Seeing a farm in person would help a lot. To get started, I have a 25 litre clear plastic tote from Home Depot that I got for cheap. I'm not sure if it's BPA free and I doubt it's meant to hold water. However, it is flexible and appx. 10 inches tall. I have attached an image. Is the volume too small? I will up scale if necessary. Should I use this as a grow bed or fish tank? Please elaborate. Can you recommend a pump for a farm of this size? Post a link please. What fish can you recommend for a farm of this size? What growing material do you recommend? How should I start cycling? Any other advice welcome. So that's it for my intro, I'm keen to start this project as soon as possible so I'll have fresh veg for the summer. Thank you in advance for all your help, and I look forward to learning from you all. Niall
  3. Just started my new IBC aquaponic system. 1000l fish tank and two grow beds. Now I am in search of Barramundi - they are sold out?!, information on air pump requirements for this system (1m deep), filtration etc. Advise from anbody is appreciated.
