- We use it under the liners to give support. It does not come into contact with the water
- If your system includes IBC totes purchased used, have you been able to confirm with your supplier that they were used only for food grade uses? If so, how have you confirmed this? If not, how do you intend to confirm this?
- Please note that while IBC totes can be grandfathered in when they're in already in use at the time CNG certification is sought, CNG standards prohibit the introduction of IBC totes once CNG status is obtained. Please indicate that you understand this restriction on IBC totes by checking the box here. *
- Does water circulate at a rate sufficient so that the water volume of the fish tanks(s) recirculates each hour? If it recirculates at a lower rate, please explain. *
- Briefly describe how your system achieves appropriate aeration. *

- Do you use Municipal water? *
- Do you use well water? *
- What are the ground water contaminants of concern in your region? *
- No, however we still invest in having our water tested every two years by an outside laboratory
- What experts did you consult to determine contaminants of concern? *
- Well and laboratory experts
- Have you tested your well within the past year, and if so, what were the results? *
- Yes - the water is within acceptable standards (200 different test results): total Coliform and E. coli were ABSENT in the sample. Hardness, total dissolved solids were noted, though our water softener helps in filtering those to a better level.

- Water softener
- Do you use rainwater? *
- Do you use surface water? *
- If you use a water source that is not named here, please elaborate.
Water Quality: Nutrients, pH, solids

- Testing the water daily - pH and DO Testing the water weekly - ammonia, nitrite, nitrate If any of the tests are showing signs of extremes or depletion we would adjust to correct.
- Please describe how you design and operate your system to provide biofiltration that corresponds to production of fish waste and crops. *
- Fish tanks, solid separator, bio-filter, sand filter, pumped up to grow beds, gravity brings water back down, UV light, bio-filter again, back to the fish tanks
- Do you ever add supplemental nutrients? If so, what materials or products have you used? List ingredients and product names. How much of these do you use? How frequently? *
- Do you use worms in your system? *
- What materials do you use to buffer pH? *
- Citric acid to lower Potassium Hydroxide to raise

- pH? *
- twice daily
- Temperature? *
- twice daily
- Dissolved oxygen? *
- twice daily
- Ammonia? *
- Nitrites? *
- Nitrates? *
- Use this space if you'd like to share additional information about your water quality and monitoring practices.
- We test for calcium, potassium, phosphates, dissolved solids, hardness, and iron monthly
Seeds, Transplants, and Crop Health
- Do you grow some or all of your own transplants? *
- Do you purchase some or all of your transplants? *
- Describe your primary insect pest challenges AND methods of prevention and control. (Do not answer "none". You MUST indicate actual pest challenges or LIKELY challenges, and you must ALSO indicate how you manage or how you would manage them. If you indicate a product, also specify how often it's used.) *
- Fungus gnats, thrips - we use a wet/dry vac as often as once a day to control adult insects and mosquito dunk as needed to control larva (Mosquito dunks are a registered trademark of Summit Chemical Co. The EPA Registration is No. 6218-47. The active ingredients are: Bacillus thuringlensis subspecies israelensis solids, spores and insecticidal toxins (Aedes aegypti mosquito) - "For Organic Production" per the label.)
- Describe your primary plant disease challenges AND methods of prevention and control. (Do not answer "none". You MUST indicate actual disease challenges or LIKELY challenges, and you must ALSO indicate how you manage or how you would manage them. If you indicate a product, also specify how often it's used.) *
- We have seen root rot in some plants that have stayed in the beds too long - other problems have been caused by thrips, which we have so far been able to control with manual methods and removing any plants that may get infested. In the past we tried Neem and natural soap, but they were not as successful as we had hoped - manual control (so far) has been the most effective.
- CNG certification requires the use of certified organic or Certified Naturally Grown seeds whenever available. Please indicate the suppliers from which you source - or will source - your seeds if your application is accepted and you continue the certification process. *
- Johnny's seed, Botanical and Seed Savers.
- Please indicate, by entering your initials, that you understand that CNG strictly prohibits the use of chemically treated or GMO seeds. *
- Please indicate, by entering your initials, that you will as a general rule purchase organically grown seeds, AND that you will only purchase conventional seed when the variety you wish to grow is not available in certified organic or CNG form. For each variety purchased in conventional form, you will identify (and keep records of) at least three commercial organic seed suppliers who do not carry that variety. *
- We do not offer certification for fish, but do set some limited standards for fish management where they might affect the produce and or quality of life for the fish.
- Does hormonal sex reversal treatment ever occur on-line / within the recirculating system? *
- Please describe the practices you use to prevent and treat fish disease.
- Salt treatments and quarantine when needed
- Have you ever found it necessary to use antibiotics? *
- Please describe what kind of fish feed you use. Is it organically grown? (For aquaponic produce certification CNG standards do not require that the feed be organically grown, but we are interested to know what producers are using and to give credit to any producers who may be using organic feed) *
- fish pellets formulated for yellow perch
- Do you use black soldier fly larvae or duckweed as supplemental feed? *
- Do you use any supplemental feed besides BSF larvae or duckweed? If so, describe it here, and indicate how you protect against contamination of your system. *
Protecting Against Contamination
- Is your operation partially or entirely INdoors? *
- What are the nearby land uses? Are there any that might pose risks of contamination? *
- residential at this time - near future (spring 2017) to move to a rural piece of property (unimproved property to the south & east, north is a road and 3-acre farmstead with horses) - no risk of contamination
- How does your ventilation and air filtration system prevent possible contamination? *
- Exhaust fan disperal and recirculation air system
- Do you share space (including fish tank, seedling starting, or plant production space) with other producers? *
- Is your operation partially or entirely OUTdoors? *
Waste & Energy
- These questions will not determine certification status, but are intended to encourage producers to review our recommendations in these areas and to give credit to producers who have made investments in the sustainability of their operation.
- How do you dispose of fish solid wastes? *
- There are two ways - depending on the time of year - during the spring, summer and fall we capture it and diaper it into our gardens In the winter it is discharged into the sewer system
- When necessary during system change over, how do you dispose of nutrient-rich water? *
- We would capture it
- What measures have you taken to conserve energy, improve energy efficiency, and/or use energy from renewable sources? (This could include system design, siting, insulation, crop and fish species selection, and more.)
- The one pump and all the air blowers are energy efficient - the air circulation is done by an energy efficient heat pump - walls are insulate with energy saving insulation - any pipes exposed to the outside air are wrapped with insulation. The fish we use are yellow perch (Perca flavescens) which are native to IL. All seeds are organic. Our supplemental lights are LED and energy efficient floresent.
Inspections & Networks
- A core requirement of CNG certification is the on-site peer-review. Getting this completed is facilitated if you're a part of a network of aquaponics producers who might serve as your inspector. Are you a part of a network (informal or formal) of aquaponic producers in your geographic area? *
- I understand that only the produce, NOT the fish, can be labeled and sold as Certified Naturally Grown. *
- I will not label, or in any way lead consumers to believe that produce not raised in accord with CNG standards is Certified Naturally Grown. *
- I understand that I have to complete at least one Inspection(s) of another CNG aquaponic producer in my area each year, if there is one within a one hour drive. *
- I understand that the inspection I conduct will NOT be of the same producer that inspected me. *
- I have reviewed the Certified Naturally Grown aquaponic certification standards, I understand them, and I will abide by them. I understand that if I have any questions I may contact CNG for clarification. *
- You may use this space to tell us anything else you think we should know about your operation.
