    Hi all,

    It's been a while since the AQ calculator has been released. We would appreciate some feedback about the calculator, good and bad. Thanks.

    Great! Have been using it. Any plan to expand it? Maybe some fertilzer calculator and metrix conversion?

    Cheers

    I love the fact that previous calculations can be imported to the next one.

    Also, the calculations on the costs of runnign the equipment is quite helpful.

    Conversions would be good.

    Let's list the conversions required:
    - Volume: Litres, US Gallons, UK Gallons
    - Length: Meters, Centimeters, Millimeters, Inches, Feet
    - Temperature: Celcius centigrade, Farenheit
    - GH(KH): dGH(dKH), ppm CaCO3, meq/L (note KH and GH refer to different things, but their unit of measurement is the same.)

    Anything else?

    What abt "drop" - "teaspoon" - - "Milliliters" - "ounce"?

    Hmmm... drop? Is there an official volume to that?

    Ounce is weight.

    Let's list the conversions required:
    - Large volume: Litres, US Gallons, UK Gallons
    - Small volume: Millilitres(cc), Teaspoon, Tablespoon
    - Length: Meters, Centimeters, Millimeters, Inches, Feet
    - Temperature: Celcius centigrade, Farenheit
    - GH(KH): dGH(dKH), ppm CaCO3, meq/L (note KH and GH refer to different things, but their unit of measurement is the same.)

    Anything else?

    Can we have something to help with the 'ppm' measurements?

    A suggestion, can we list US Gallons as 'Gallons' and UK Gallons as 'Imperial Gallons' or 'Gallons (UK)' since we generally deal with gallons as a whole to refer to US gallons. This will make things less confusing...

    Personally, I prefer the Rebel Gallons...

    Anyway, I like the idea... it'll be less confusing for the newbies.

    Have a calculator for calculating KNO3 and KH2PO4. The one at kribs is not accurate cos i've checked and realised that the nitrates and potassium content in their KNO3 is very different from Dr mallick's. Same for KH2PO4.

    Another thing is it's very convenient to have EVERYTHING (eg calculator for the main fertilizers pple normally use, CO2 level in the tanks etc etc etc) in this forum. No need to go elsewhere to calculate things. Next time people from other wesite will have to come to this forum to calculate all their stuff, which means better and wider exposure for aquaticquotient.

    Conversion of dKH to ppm? is that even possible?

    What do you mean? Because KH and GH can be expressed in units of "ppm CaCO3".

    Or do you mean given a target KH to raise and target water volume, we calculate how much baking soda to dose?

    That's the plan... bwahahahahaha.

    It would be good to have a Crude volume measure as well as seeing the “Refined” or “Effective” water volume for pmm calculations.

    Crude = L x W x H

    Refined or Effective = Crude volume – [Glass thickness, Rocks, Wood, etc + Filter water volume]

    • Glass Thickness
    • Rocks [weight = water displacement]
    • Estimated wood volume
    • Substrate thickness
    • Water level from top of the tank
    • + Filterwater volume which can be quite a bit if you have a sump or couple of 2028's or larger

    Rupert,

    Personally, I've never found it necessary to be so precise. After all, no one knows the precise amount of each nuitrient required. All the targets are estimated. Precise amounts leftover after plant usage and water changes are not known either.

    I just minus away a percentage base on visual estimation. It's easy to subtract the substrate from the water volume. Same when including water volume from large filters.

    But for the rest, I deduct about 10 to 30% depending on contents of the tank.

    I tend to err on the side of excess nuitrients.

    Oh, the other thing is, we don't want to spoonfeed too much.

    "Effective" water volume can easily calculated by doing a mental subtraction of the average substrate height from the water height, and using that number instead of the actual tank height.

    Frankly, this hobby does required some brains and work, and if someone refuses to get their brains into gear to do some work, they are not likely to succeed.

    I don't mind putting the effort to program the chemistry and fert stuff that is a challenge for a lot of people to figure out, but not for stuff that can easily be deduced or calculated with some mental, or pencil and paper work.

    Temperature converter:

    T(°C) = ( T(°F) - 32 ) x 5/9

    T(°F) = ( T(°C) x 9/5 ) + 32

    By providing the ability to calculate to a more precise level is about letting people make more informed/calculated decisions at a more detailed level if they need to. It is about being more precise rather than generalizing about water volume. An assumed understanding of water volume will lead to greater variation in other downstream calculations, especially as we are already talking about ppm in many of these calculations.

    I agree that it is sort of spoonfeeding in that we want to point people in the right [or wrong?] direction of considering what goes in their tanks will impact water volume and specifically by how much. This is for the school kid in the classroom, which there must be many members who may not make the immediate link between more hard-scape equals less effective water, which equals less fish.

    For the more experienced person who doesn’t want to generalize, specifics will draw them to re-using the calculator as part of the regular dosing regime… how much of chemical X do I need to raise KH to 3.0 from 2.5… and what pH will indicate CO2 is maintained at 30pmm

    Then there is the consideration that having a calculator that has so many fields presented on one page would take a long time to load. Anyway just some rough thoughts

    Hahaha... the loading part is not an issue. Trying to figure out how to lay out the fields and buttons is the problem. That's always a headache for me. Fortunately, my day job is to program software for kindergarten children and that means minimising the number of controls available.
