Growbed media's Biological Surface Area For Fishtank size
Calculate how small your growbed needs should be to be safe enough for your fish tank's size. The ratio between the sizes of the Grow-bed and the Fish-tank depends on the biological surface area (BSA) of the Grow Bed. Aquaponics has 3 main steps: Fish poo making ammonia. Bacteria colonies transform the ammonia into nitrite. Trees absorb nitrites to grow green leaves. The bacteria live on the BSA surfaces of the rocks which meet both air and fish water. So we control the amount of biological surface area so when the bacteria colonize %100 of the BSA the fish tank's toxic water is converted to healthy water. More rocks or more sand means more bacterial surface area. You can't have too much BSA, more the merrier, but it's toxic for fish to have not enough BSA. The Calculator. This calculator works out the maximum size your fish tank can be for any type of growbed. Media is the word used to talk about the rocks or...
