    I make this fertilizer with help of this forum. I make a limited quantity for sell to my aquarist friends here in Puerto Rico.

    Thanks

    The NPK + Ca looks like a neat marketing trick.

    How did you manage that one??? :D

    Looks good. I'm also curious about the Ca+

    Do you have an analysis on the other side? It's helpful for people to be able to see what they're dosing, and so they can compare to other products.

    Yeah it have the analysis. It is in Spanish.

    The Ca is form CaCl, mix it first with water, can get pretty hot. Then dose the KNO2 and K2H2PO4. It dont react. only shake the Ca (gets to the bottom in a hour) and the liquid turns white. Then dose.

    Im using it now in my 5G Natural aquarium tank. Only 3 products, these 2 and Excel. Everything is going good and the Cherry shrimps are breeding more. I dont know, maybe more minerals in water???

    PS: The front label in English is also a neat marketing trick.

    If you're having to shake the bottle, then you're getting calcium phosphate precipitating. This is why I haven't combined it that way in my own solutions.

    Hi,

    Can cacl2 precipitate by itself? I am asking b/c my cacl2 solution has a "lemonade" or very light tea color and also, I have to shake the bottle every time I am dosing.

    It looks good on the label.

    Is there a way Ca could be added to NPK formulas, even if it is only a small amount? I will continue to make my stock solutions with out, but I would buy it. Just seeing the Ca added to the NPK would make it very compelling to some of us lemmings. I pay for added Ca to my orange juice and that probably makes no sense. :rolleyes:

    I've never had CaCl2 precipitate on me as the sole solute in a solution with DI H2O. I've got bottles that are months old sitting around looking fine, mostly because I hardly bother with the stuff anymore.

    And since Tug and I bumped into each other on posts, I'm going to double-post as a reply.

    I don't know a way of getting significant Ca in with phosphate. KNO3 should be okay, but anything hauling around PO4 or SO4 with it is going to combine with free calcium and precipitate.

    Hi,

    Then, what can cause this? I mixed it with Poland Spring bottled water, that's it. (220 grams in 1L water) I bought the cacl2 from AquariumFertilizer. OK to keep using this solution? Btw, this is the second time I made cacl2 solution and both times the same thing happened.

    Well, I will check with a Phosphate test.

    Still is like a weird because the product is working, It dilutes in the aquarium. Plants seems to like it :D

    "Solved"

    Hello,

    OK, I just made another solution (100gr/500ml w) and this time it came out quite clear and no precipitation but, this time I used a new batch of dry cacl2 2h2o. I think, either the previous batch of dry cacl2 2h2o was "bad" or something was wrong with the bottle I mixed it in. Do I need to add HCL or Metricide to this to keep it stable?

    Barbarossa, you don't need to add anything IME; I haven't had any contamination issues. A little HCl would be recommended if you're passing it on to others; some people can find a way to contaminate anything.

    Brian, the product would work, but the calcium and phosphate dose is unstandardized that way. Odds are you'll start adding more PO4 and Ca+ near the bottom of the bottle.

    yeah, still if I shake it, it not precipitate fast, it took 2 minutes approx.(I check it with a clock) to beggining to precipitate. The only way to dose it well is to shake well and dose fast. You know, I also sell dry fert, but i sell more fast the liquid fert (despite that I make the liquid ferts from dry ferts and everybody knows it). I think here win the easy way to dose (Only 2 products, only fill the cap). I start to use this 2 bottles on my 5G because it is so easy and have all the nutrients needed, but in the 29G Heavy planted I use the dry ferts. Thank you again people and thank you Philosophos.

    OK, thanks Dan.
    I think, I contaminated the bottle when I made the first 2 solutions. This time I boiled the bottle for 5 min or so. The new one I made last night looks OK.

    Brian20,
    Why not take the Ca out of the NPK solution, avoid the precipitate problem and come up with your own GH booster for the water in your area?
