Switching to Bleach?

[CToon]

Hi Jim ,

Have you tested for your CYA level ? It is important to know so you can figure out where you need to keep your CL levels at.

Have you downloaded MWsmiths Bleach Calculator ? It will tell you how much bleach you need to achieve CL levels

One caution about rellying on the pucks to chlorinate the pool . Pucks can quickly raise the CYA in the pool to a point it becomes a problem. trust me I know

Thanks for the quick reply.

I found that site bit I don't know how to use it. The length of my pool is 32ft, the Chlorine Strength is 6 I gather and the desired PPM is 5.

I don't know what the quantity should be.

My CYA was high but I've been adding more water lately in an effort to get it down.

Any examples of how this is calculated?

Thanks

I guess L means Litres not length so I need to find a gallon to litre conversion chart

to change the calculator to Gallons go to More Calcs in upper left , go to settings ,click imperial (its u.s gallons ) you can also put in pool volume and bleach values.. save and close

if you dont know the pool volume , the calculator has a thing for that too. bleach strenght is almost always on the bottle ( generic store brand dont always)


oops prh beat me too it

You should know --- an Imperial Gallon =1.20095 US Gallon ---- THEY ARE NOT THE SAME!!!!

Jim, I recommend that you not add bleach directly to the skimmer. When you do, relatively undiluted bleach can reach your inline chlorinator and have disasterous results (like an exploding chlorinator). I understand that this can happen even if you empty the chlorinator of pucks and is probably likely if you don't empty it.

On your pump run times, you're probably better off to split your pump runs into two or even three different segments instead of one big twelve hour stint.

Won't pouring straight Clorox into the pool and onto the vinyl liner bleach the color out of the vinyl faster.

I would have let this slide and had this thread continue on with helping Jim , but since you have chosen to point me out and YELL at me what an Imperial GALLON is , my good sense is just going to take a back seat on this one and so be the consequences...

I KNOW WHAT AN IMPERIAL GALLON IS !!!!!!!

I was pointing it out specifically because the program says imperial , however uses U.S gallons for the computations. thank you very much

In case you didnt know before this , CAPS are considered yelling on internet forums . And in almost all circumstances considered in poor taste and/or known to raise the ire of the person you direct it at. So the next time you feel the need to impart your wisdom upon me by yelling it at me , do me a favor and just move along quietly

Hi Jim,

First, go to More Calcs and click on Pool Volume. Put in the dimensions of your pool in the box that fits the pool description (rectangular etc). The settings tab in More Calcs lets you choose between litres and gallons.

Now you can go back in the main screen and enter your pool volume and your bleach strength. In the Chlorine section of the forum, you will find Ben's Best Guess chart for figuring out the chlorine level you need based on your CYA level. Find your target chlorine level and look at your free chlorine test reading to see how much you need to raise your chlorine level up (in ppm). Put this number in the program and hit calculate and it will tell you how much bleach you will need to add to your pool to make that happen. Hope this helps.

Thanks Guys

I think I got the volume right. So we just pour the Liquid Bleach in the skimmer in the evening after everyone has stopped using the pool. Then run my pump all night long.

From other threads I've read it seems Clorox is 6% and that's what I've used in the calc.
