Fish are most comfortable in large tanks so estimate at least 1 800 gallon tank for a profitable aquaponics operation.
Aquaponics grow bed to fish tank ratio.
This ratio can also be termed and determined using different parameters.
In general the recommended grow bed to fish tank ratio is approximately 1 1 i e.
There are 6 types of grow bed designs in aquaponics all differ in the way they deliver the nutrients to plants.
Use 45 grams if you do not discharge solid fish waste and 120 grams if you discharge solid waste to your garden.
As the fish grow it increases in length width and height.
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.
You will need to feed your fish 15 40 grams of fish feed per day per square meter.
System design and grow media.
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.
This is only applicable for smaller tanks.
The fish tank volume should be approximately equal to the volume of the grow bed.
In general it is recommended that fish tank volume should be approximately equal to the volume of the grow bed which makes the suitable grow bed to fish tank ratio equals to approximately 1 1.
You need to feed 45 to 120 grams per day to your fish.
You cannot follow this rule to stock the fish that have a tendency to grow larger.
