What calculators would you like to see?

[KyleT]

Hello everyone,

endparenthesis has very generously offered to upgrade our existing calculators as well as code up some new ones for everyone. Before he gets started what calculators would you like to see implemented?

Also if you know some of the calculations as well please shoot myself and endparenthesis a PM.

Volume calculator

CO2 calculator

I second the volume calculator.

[endparenthesis]

Don't forget basic ones too... the ones we might take for granted but that someone somewhere would appreciate. Like converting KH degrees to ppm... or gallons to litres... that sort of thing. I'm hoping for it to be as comprehensive as possible.

My tanks aren't nearly as high tech as some people's so some of these I just won't even think to add without your suggestions.

A substrate calculator that applies Onyx Sand, ADA substrates, etc.

Gram weights of Calcium chloride and MG at a given ratio (say 4:1) to convert RO water to a given desireable GH (say 5GH). I know these amounts, but it was very hard to find. With the caveat not to add these two at the same time or it results in hard to dissolve calcium sulfate precipitate.

I would use everything that has been submitted so far.

Also it would be cool to have a fert calculator, but what would be really cool and what would set this above the rest was if it was made so one could just put in the size tank they have, select Co2/ no Co2. Low light, Medium light, high light and it would spit out the amounts of each fert you need to add to the tank to get the recommended amounts for your application. Lastly have it give you a dosing routine based on the frequency of your water changes. Weekly/ bi-weekly/ monthly?

If you guys can plan out all the calculations (the actual numbers) and provide them here, no problem. I need the help of the forum experts on how the data should be manipulated... I'm just making the interface for it. I've never done a high-tech dosing regime, so you guys don't want me planning that part out.

Please feel free to outline all of the actual calculations here. The only calculations I currently have are those that I can google (e.g. unit conversion, tank volume).

I have a spreadsheet that has a lot of calculations in it. I could send to you. I would feel even better if someone would check it for accuracy

I'd like to see IE dose recommendation which would include CSM+B as well as Chalated Iron for those who like to dose both dry in grams.

I am going to Sticky this for maximum exposure. The more user input the better.

I'd like to see Soilmaster Select/Pro added to the substrate calculator.

[endparenthesis]

I need numbers, guys. I really only have so much time to research this stuff, and much of it I wouldn't know better than some of you anyway.

Ok, to start with... can anyone who has a bag of substrate handy post the coverage instructions given on the bag? Usually pounds per square inch or vice versa.

I have the numbers for a few substrates, but I want to get the numbers from the source anyway just in case.

For regular old sand I believe it's 8.2 lbs/ft2 (1 in depth), and regular old gravel is 7.5 lbs/ft2 (1 in depth), but I'm not totally sure. Flourite I think is 62 in3/kg, but again not sure.

Chuck Gadds C02 calculator, and any of his other ones

Volume calculator has already been said, and I agree. But I REALLY wish we had a volume calculator that accurately took into account the thickness of the glass. That is where almost all the volume calculators out there fall short.
