You need to feed 45 to 120 grams per day to your fish.
Aquaponics grow bed to fish tank ratio.
Step 2 add grow beds in a ratio of 1 1 start with a grow bed ratio of 1 1 which is 800 square feet of grow beds for an 800 gallon fish tank.
This is a crucial factor when determining the number of fish you can keep ie your fish to water ratio.
The three growbeds have a combined grow area of 3 square meters.
This ratio can also be thought of in gallons per cubic foot striving for 6 gallons 22 liters of fish tank to every cubic foot of grow bed.
There are 6 types of grow bed designs in aquaponics all differ in the way they deliver the nutrients to plants.
This is only applicable for smaller tanks.
This ratio can also be termed and determined using different parameters.
You cannot follow this rule to stock the fish that have a tendency to grow larger.
In general the recommended grow bed to fish tank ratio is approximately 1 1 i e.
Fish are most comfortable in large tanks so estimate at least 1 800 gallon tank for a profitable aquaponics operation.
System design and grow media.
Use 45 grams if you do not discharge solid fish waste and 120 grams if you discharge solid waste to your garden.
For a smaller fish species the most widely accepted stocking rule is that for each gallon of water you raise an inch of fish.
The volume and weight of 10 inches long fish can be more than 100 times of 1 inch long fish.
The fish tank volume should be approximately equal to the volume of the grow bed.
