Thread: Can we replace KNo3 with CaNo3??

  1. My tank is 150 gallons. My lighting is at 3W/gallon.

  2. And also I have easy access to K2SO4 So if I am to use K2SO4 and CaNo3, what should be my dosage in terms of tsp? Thanks!

    Smile Well Okay... The Kitchen Sink as Well

    Hi,

    For general, high light in a 150-gallon aquarium
    dosing three times a week assuming 50% weekly water changes:

    1.75 teaspoons --------------- Ca(NO3)2.4H2O
    1 teaspoon ------------------- CaCl.2H2O (my favorite) OR (CaSO4)2.H2O (Plaster of Paris)
    OR 2 teaspoons CaCO3 (agricultural lime OR dried crushed egg shells)
    1 teaspoon--------------------- K2SO4
    18 teaspoon ----------------- KH2PO4 OR 3 milliliters Fleet Enemas

    ½ teaspoon ------------------- CSM+B,
    2 milliliters ------------------ 0.5% Boron solution (46 grams of Borax in 1 liter solution with distilled water.)
    1 teaspoon -------------------- Epsom salts (MgSO4.7H2O)
    ¼ teaspoon -------------------- 10% Chelated Iron

    I hope this helps.

  4. Hi Billante,

    Sorry but I am an idiot ahha. So is it
    1.75 teaspoon of CaNO34H2O
    and 1 tsp of CaCl2H2O
    and 1 tsp of K2S04
    and 1/8 tsp KH2PO4

    So all these for the Micro part??

    So all these for the Micro part?? The OR kinda confused me.

  6. Sorry again just to make sure as they state it in terms of the names and not the Chemistry symbol, so what I need to dose is
    1.75 tsp of Calcium Nitrate
    + 1 tsp of Calcium Chloride
    + 1 tsp of Potassium Sulphate
    + 1/8tsp Potassium Phosphate

    Three times a week.

    Is this correct?

    Hi,

    You are not an idiot, you just don’t know yet… So long as you are not yanking the evil plant monster’s proverbial chain.

    1.75 (1 3⁄4) teaspoon of Ca(NO3)2.4H2O
    and 1 tsp of CaCl2.H2O
    and 1 tsp of K2S04
    and 1/8 tsp KH2PO4

    The above are macronutrients.

    Smile Macro---Micro All Ends Up In There Somehow

    Hi,

    The “OR” indicates a choice, in the English language “or” is a coordinating conjunction introducing an alternative. I struggle with English, as anyone who reads my posts can deduce
    . “OR” could also be viewed as a logical operator, meaning any of the statements make the condition “true.”

    In this case you had not told me what other sources of Calcium you had available so I listed three possibilities. I happen to favor CaCl2.2H2O, because I like the Cl2 part as well (that is somewhat controversial). (CaSO4)2.H2O is available almost everywhere. CaCO3 is available in a number of forms including egg shells, which most folks have access to and foolishly throw away.


    These are in the macronutrient group.


    The CSM+B, Boron and iron are micronutrients. The Epsom salts tend to get lumped in but I believe, at least technically, Magnesium would be a macronutrient.

    Smile Sometimes I Get A Wee Bit Carried Away

    Hi,

    The parenthesis, sub and superscripts are important…


    Ca(NO3)2.4H2O is called Calcium nitrate tetra-hydrate.
    • Ca is Calcium
    • NO3 is nitrate, which is made up of one Nitrogen molecule and three Oxygen molecules.
      • Notice the parenthesis around the nitrates “(NO3) with the subscript “2
      • (NO3)2, this means there are two nitrate.
    • The “.” (often represented by an asterisk) indicates an “hydrate.”
      • Hydrate indicates that a substance contains water.
      • In this case “4H2O” means four water molecules attached we refer to that as “tetra-hydrate.”
    So we have:
    Calcium nitrate tetra-hydrate, Ca(NO3)2.4H2O
    Calcium chloride di-hydrate,
    CaCl2.2H2O,
    this is often available as Calcium chloride hexa-hydrate, CaCl2.6H2O, you will need about 16% more if you use the hexa rather than the di-hydrate. If you order your Calcium nitrate from a chemical supply house you may get anhydrous Calcium chloride CaCl2.
    Calcium sulfate, CaSO4 is most commonly seen as plaster of Paris, (CaSO4)2.H2O, occasionally you will see it written as CaSO4.1⁄2 H2O
    Calcium carbonate, CaCO3
    Potassium sulfate, K2SO4
    Monopotassium phosphate, also known as potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate, MKP, KH2PO4.
    Fleet Enema’s 16 g sodium biphosphate and 6 g sodium phosphate per 100 mL solution are a great, precisely measured substitute.
    I hope this helps someone.
