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:
  1. Fish poo making ammonia. 
  2. Bacteria colonies transform the ammonia into nitrite. 
  3. 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 the sand.

Instructions before you calculate:

  1.  What's your fish tank's size?  Is your fish tank 130L? Then estimate 110L to 130L of fish-water.  plus the 1L water in the pipes and 20L grow bed. 
  2.  Media is the rocks or stones used as the base of grow bed. 

Be aware that the growbed's media values are in meters, so 10 centimeters is written in as 0.1 ; and 155 centimeters is written in as 1.55 
And If you have separate containers, then add the container grow media volumes up (into cubic meters), and just put it in "growbed medium height" and make "Growbed Medium width = 1 and growbed Medium length =1 "  
Growbed's media height (meters)
Growbed's media width (meters)
Growbed's media length(meters)
If using 12mmPeaGravel, max-max size of fishtank (litres) =
If using 12mmPeaGravel, min-max size of fishtank(litres) =
PeaGravelwater inside growbed void, add to max above (litres)
If using 3mmSand, largest max size of fishtank(litres) =
If using 3mmSand, smallest max size of fishtank(litres) =
If using 25mmRocks, max size of fishtank(litres) =
If using 25mmRocks, min size of fishtank(litres) =

For each type of media there are two maximums: the smallest maximum which is the safe size; the largest max is when fish are in danger because there isn't enough BSA to make the dirty water clean.
   
From the calculator, the minimum size of a fishtank given the growbed's media is low due to 'void' between stones. The max size of the fishtank for a particular growbed media, is assuming there is no void (i.e: after a lot of settling down. )


So, now you have the scientifically verified way[1] to create the grow-bed's base level of drain-rocks. And you can rest easy that it is likely your Aquaponics kit will be a successful blessing to the creatures living in it.

The smallest ℝeal number in Mathematics and Αlpha and Ωmega

Image
The smallest number in mathematics is invisible to science, but geometrically looks like Jesus Christ's two Greek-letters "Alpha" and "Omega". contents Defining 1/infinity Appreciating Α Ω Takeaway summary What Jesus said The effect of What Jesus said Calculus uses a special number δx = 1 ÷ infinity which is the smallest number imaginable. It is 0.0000…00001. if 1÷10 = 0.1 and 1/100 = 0.01 then 1/infinity = 0.0000000000…001 . “dx” is shorthand for the Greek letter Delta x = Δx or δx , because delta "Δ" is used in mathematics to mean ‘change in’ . δX is spoken as "d X" Revelation John Greets the Seven Churches 4John to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne; 5And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth.

Jesus' "love your neighbour as yourself" law and Calculus integration.

Image
The relationship between Lord Jesus' double law "Love eternal God and Love thy neighbour" and Calculus' integration.  Take-home lessons:  To get to  the higher dimensions of life , we must love one another.  To love one another you each must love your neighbour as yourself.  You must treat your neighbour as you want others to treat you.  You must change your view of your self, to accomodate the others as they accomodate you, and not simply just view yourself as by your self and next to other people.  By accomodate i mean, to tolerate, to accept, to get along with, to work with, to help, to be helped by, to share the world with.  The infinitesimal unit is an individual.  In geometry and in calculus, this is easily visualized. A number  is a summation of many "ones." In geometry a number is a line.  A line is a summation of lots of (1/infinity big) dots in sequence.  Each dot has two n...

Prompt-driven Programming

Fine-tuning prompts for programming tasks involves clearly defining the problem, specifying the input and output format, and sometimes providing examples. Here's how you can do it: examples edge case sequences ambiguities clarify the problem specify inputs specify outputs comments 1. **Define the Problem Clearly:** Be clear and concise about what you want the program to achieve. The problem statement should be explicit about what the task involves. 2. **Specify the Inputs:** Clearly define what the inputs are and in what format they will be given. This may include the type of the data, the range of possible values, and any other relevant information. 3. **Specify the Outputs:** Similarly, be explicit about what the outputs should be. Describe the format that the output should be in, whether it's a certain data type, a particular data structure, a specific range of values, etc. 4. **Provide Examples:** Provide examples of input and output pairs. This can help to c...
