    Roof Cleaning With No Effect On Plants ?

    I have been all over various ask it boards for some time, always trying to improve.
    Here is a link of me asking a question about Calcium Hypochlorite
    https://ask.nsdl.org/default.aspx?id=12505&cat=1188

    I as told on another board by a Plant Scientist that I should consider switching to Calcium Hypochlorite because it's breakdown product is Calcium, not Salt!

    here is a link supporting that http://www.kitchenculturekit.com/calciumhypo.htm

    According to this answer I received, we only need 43 pounds to get up to 7 percent equivalent strength of Sodium Hypochlorite ?

    Sheet, that would actually be cheaper too http://www.waterwarehouse.com/products/sku-4858.html

    Have we found the "promised land" ?

    Seems simple ?

    Since we have 500 plus gallon tanks, we simply dump 43 pounds in, stir, and wait overnight ?

    The question IS, how much for a pound of that stuff ?

    If this is true, just THINK of the implications ?

    All you need do is spray, rinse plants, and walk away.

    No worries about sodium poisoning like what happens when you leave SH on a roof!


    C'mon guys, get into this thread, we might be on to something ?

    There is a link on the first post Russ.

    I swear to Gawd Russ, I asked this question on another ask it board, and a Botanist suggested switching to calcium hypochlorite!

    Now, I "tried" it a long time ago, but maybe I didn't use enough, and it was kinda expensive.
    It did not work, and i never went back to it.

    Liquid Chlorine was cheap then, it isn't anymore!

    It is important to remember the formula of 43 pounds Calcium Hypochlorite per 500 gallons is for pure stuff.

    The Pool Grade is only 65 percent, so we need almost double.


    But still ....... we can get 50 pounds shipped to us for under a hundred bucks.

    Even if we did need double, it is still in line with liquid chlorine ?

    Think about it ?

    In a 500 gallon tank, we need about 200 gallons of chlorine anyway, and that stuff is over a buck a gallon now.

    So, price would seem about the same ?

    BUT, if it has less effect on plants .........

    That's the stuff Scott!
    But remember, the "formula" the scientest answered me with is for PURE stuff.

    Pool Grade is only 65 percent, so we neeed to almost double it.

    It is not very water soluble, but will eventually dissolve, mix well in advance.

    Man, if this would only work it could change our lives?

    Rinsing is a pain.

    The way I understood it is that the calcium does not sodium poison like SH does ?

    So, we need only be concerned with contact during the cleaning process.

    Wouldn't it be nice to "walk away" in confidence ?

    Hey, it MAY even be easier on pumps too ?

    We MUST explore this, I think ?

    I Love You Chris

    Chris:
    You are one of the very few people in our industry that is always thinking, Ken Barlow is another - a pioneer and very successful.

    In the spirit of Christmas (and as a public service), I would like to let you guys know that calcium hypochlorite is not a very good idea.

    Calcium hypochlorite is a VERY dangerous chemical and exposure to fumes (which will be created as soon as you add water) can result in severe and irreversible lung damage - and it does not clean very well.

    Happy New Year to All!!!

    John, I value your opinion. Do you have any other references to back that up. MSDS or any other sources?

    Experience is all we can call on – and $40k in medical
    If you’re in doubt, give it a shot – I am quite sure that at least a few here will.

    And Merry Christmas to you and yours.

    I have heard that before about Calcium Hypo, that it can be some nasty stuff.

    I tried it once, years ago, and it didn't work, but I may not have had enough ?

    I will have to look at the MSDS

    You have actually tried it right ?

    That's where I have seen his name before. I looked into roofacide 3 or so years ago and talked to a couple different guys. It wasn't right for me, the had some pretty good ideas though.

    Just so y'all know. I did try Cal Hypo. 10 to 1 ratio.
    smells like it will work, but it doesn't.
    We used to use it a little in my pool contracting days. CHL (liquid) is the best.

    I tried it too David, no luck.
    But, according to the formula, I did not use enough.

    Regardless, John Brown from Roof A Cide said he did try it, and it didn't work, and that's good enough for me.

    John and I go back, way back, to a time when he cleaned roofs just like we all do now.

    He is very knowledgeable chemically

    A few months ago when I was picking up some non roof related chems from a supplier. Thechemistrystore.com to be exact.A guy I'm assuming was the owner tried to sell me on the idea of cleaning roofs with oxygenated bleach.He said it would only be active for an hour(or maybe it was ten minutes I cant remember) after mixing up a batch and wouldnt harm plants.Has anyone ever tried this?
