Module 3
Growing more fish and plants for human consumption and enjoyment
Review: Module 2 - Beds, Filters
What are the filter types?
•Ebb and Flow
•Flow through
•River bed
•Deep gravel
•Strawberry tower
•NFT
Nutrient Film Technique
•DWC
Deep water culture
•Raft method
What does the bell siphon do?
•Aerate water in gravel beds
•Aid biofiltration
What else do Grow beds do?
•Grow plants
•Collect solids
•Host earthworms
•Convert Ammonia
Cost?
Develop safe reliable system using one pump
(cid:57) Utilize gravity
(cid:57) Understand head, hp to watts to kwh to
cost
(cid:57) GFIC required
Understanding dissolved oxygen
(cid:57) Venturi
(cid:57) Sheeting
(cid:57) Use Flow form aeration where ever
possible
Understanding filtration
(cid:57) Gravel beds for trapping solids and also
for additional biofiltration
(cid:57) Ebb and flow – Build simple bell siphon
prototype
(cid:57) Flow through beds
(cid:57) NFT- Nutrient film technique
(cid:57) Low cost main biofilter
Plants are for
(cid:57) Nitrate removal
(cid:57) Ammonia removal
(cid:57) CO / carbonic acid production
2
Meet plant fertilizer needs
First Prototype (cid:57) Grow plants in soil if not aquatic
(cid:57) Soil based plants - vermicast, cocopeat
(cid:57) Dependant on capillary action of potting
soil – we have ideal materials

Bed types for plant types
Soil based Plants get soil
Water based plants get gravel
Floating Plants get to Float
