Development of a new dosing calculator, come help

Re: Development of a new dosing calculator, come help

Jason has offered to help and add some input here:
All are welcomed to think outside the box with this utility and make it more useful to the membership here.

I'm considering something that shows how much ppm are left after dosing a week's worth of nutrient, with a given water change%.
Then a prgram that shows the dilutions as say 25% of the NO3 are used up, 50% or 75 or 100% etc.

See the EI article's gragh example with 10ppf NO3 added.

Also, basing the uptake on substrate concentrations(see uptake graph based on the Droop model).

These are modeling prgrams and can be done to predict the outcomes in terms of nutirents or growth rates/uptake rates.

This way you can plan and predict what these levels might be and know how much is being used up or not.

This is thinking way ahead of the calculators that are now being used.

Chuck Gadd has offered his for the site also.

I'd also like to add an estimated ppm number for ....if you added say 10ppm NO3....... you'd need x amount of Fe to provide non limiting conditions.

Basically an elemental ratio plug and chugger.

So what would be the N ratio for 10 ppm NO3: 1ppm PO4 in terms of N.........

That type of ratio to compound, ion convertor.

So you could say I use 10:1:20 and trace at 0.2
GH would be 4:1

CO2 would be C at 200, N 10, P 1, K+ 20, Fe as proxy for traces at 0.2


The other issue would be adding a water change % variable and a frequency of water change variable to predict max ranges and build up.

This would be far more powerful that the cals out now.

We would split the cal into 3 mainsections:

Dosing nutrients
Water change/frequencies
Nutrient ranges with both of the above functions.

We can also add a CO2 function into this= add pH and KH => CO2ppm, no table format.

If this could produce a graph with the input sets, that would simply awesome.

A DOS prgram can write this type of stuff, we used it in ecological modeling.
It was not that hard for them to do this as I recall, but I'm no programmer.

Main thing here is to start simple with a nice looking dosing calculator,
We can add and build to it here and there as folks have time.

I want some of the same things the other calculators preform but these calculators have so much more potential!!!!

Graphing fuction over time based on a dosing rate would way cool and relatively easy to do.

Fish poo can be worked in also.

With the graghing and % used, you can estimate the the relative contribution for the fish.

You can do this now by removing the fish and then adding them back again and testing.

But you can also get a rough idea based of the % estimated that you use using the graphs.

We need to consider fish food and the analysis of the nutrient content(we'll assume 10 % lost to the fish, 90% to the plants).

There are many functions the calculator is capable of.

But keep it simple and build it.
I'm just brain storming right now and wanting to get a basic item working.

When folks think about these other possible functions, often they go off and make them so I like to get them out there and see if they are of use or can be improved upon or honed even better.

Yes, I think Jason might be but Chuck Gadd also may help and there are other victims.

I like the version you have that expresses it in verbal form.

Good work.

Yes, we develope software for the State of CA here and building a data dictionary for our monitoring program. We use similar flow charts for this design.

I have plenty of Flow chart flow diagrams like those availaable on Microsoft PP and MS Word. I can give the needs and ther data dictionary can be built around this.

Yes, existing tap water would be great!

I'll make a listing of different parameters and functions we might add.
From there we can build the dictionary and then use the prgram to plug and chug most any need the aquarist might have with fertilizing.

This more formal process in software application has not really been done but
I think would go a long way.

I think it is very powerful and offers us a lot of conveniences that have yet to be done yet is not that tough to make once we decide what the parameter inputs are.

Re: Development of a new dosing calculator, come help

Yes, you are correct, all those play a role, but........they also can be addressed also!

See maximum uptake rates in the EI article to get an idea.
But the issues you raise will be put into the program.

Re: Development of a new dosing calculator, come help

Sounds good to me Robert.

I like the idea of a simple cal for most folks and then a modeling cal for the nerds.........

That would rather easy to set up.
Anyone that wants to do that, go for it, we'll place your name up and it'll get a huge amount of usage as well as be free for any one.
