Welcome
to Cabbage Hill Farm
Cabbage Hill’s Aquaponics
System…
Four Tank System
(cid:190) Nutrient-rich fish water is fed
from tanks to rotating drum filter
(cid:190) The filter removes solids greater
than 60 microns
(cid:190) Greater than 60 micron solids are
vacuumed off drum filter
(cid:190) Filtered water is piped to NFT
growing beds
NFT Growing
(Nutrient Film Technique)
Beds
(cid:190) Drip tubes feed plants
(cid:190) Plants absorb nutrients they
need
(cid:190) After plants filter nutrients the
water passes through gravel
beds under the NFT trays
Water Return
(cid:190) Gravel beds host Nitrifying
Bacteria which convert toxic
Ammonia into Nitrogen
(cid:190) Cleaned water returns to
tanks
Solid Separation
(cid:190) Vacuumed solids are sent to
settling tank
(cid:190) Baffles trap solids
(cid:190) Remaining water flows to
sand bed filter
(cid:190) Sand bed filter contains
wetland plants which absorb
Phosphorous and Nitrogen
Composting
(cid:190) Trapped solids are pumped
to compost piles
(cid:190) Compost provides high-
quality fertilizer for outdoor
gardens
Successful Vegetables and Fish
Vegetables:
(cid:190) Lettuce and Micro-greens
(cid:190) Watercress and
Wheatgrass
(cid:190) Basil and Chives
(cid:190) Wetland plants
Fish:
(cid:190) Tilapia and Yellow Perch
(cid:190) Bass and Trout
(cid:190) Walleye
Tilapia are the fish of
choice for Aquaponics
(cid:190) Nile Tilapia (Oreochromis
niloticus) are the fish of
choice for most aquaponic
operations
(cid:190) These fish are easy to raise
and make a lot of fertilizer
(cid:190) When these fish reach 1
1/2 pounds they are sold to
a local market
Tilapia are Caught and Sorted
