To ensure a successful sustainable aquaponics operation, the best ratio between the grow bed area and the fish tank volume must be achieved.learn how to optimize this ratio for your aquaponics operation below, to build a healthy aquaponics ecosystem.. Aquaponics, growing fish and vegetables in your own backyard. aquaponic systems, information, workshops and components ratio of fish tank to grow beds. posted: thu aug 18, 2011 5:06 pm . seriously, this cant be healthy. then you need the 2:1 grow bed-fish tank ratio and a sump tank or means of sequencing.. From grow bed area, determine the fish weight required (pounds or kg) using the ratio rule 1 lb (.5 kg) of fish for every 1 sq ft (.1 sq m)of grow bed surface area, assuming the beds are at least 12″ (30 cm) deep..
And when you are talking about ratios you mean the amount of water that the fish tank will hold compared to the amount of water the grow bed will hold (displaced by the growing media). as opposed to how much liquid each empty container would hold.. A two, deep-media grow bed system can support about 40 pounds of fish with our current design of ample fish tank and grow bed aeration, and works out to about 3.3 gallons of bio-filter grow bed media (hydroton) per pound of fish.. 4) determining the ratio of grow bed to fish tank as a basic rule of thumb, you should start with a 1:1 ratio of grow bed volume to fish tank volume. once your system starts to mature within 4-6 months, you can increase it to 2:1 if you really want to..
