I have noticed that my local Walmart is always nearly sold out of the Walmart brand of 8.25%. The shelf is usually mainly empty with only one or two bottles left, and sometimes none at all. By contrast the shelf with the Chlorox, which is priced at $1 more, is totally full. I can't believe...

Thanks chem geek! That is what I was thinking. Totally different system, with different principles of operation. The fact that the chlorine and water do not mix thoroughly in the Liquidator is not related to feeding a completely mixed bleach solution by gravity directly into the pool water.

I don't know if this is approved or not, but that is what I did when some small mosaic-type pieces came loose, using a thin-set mortar specified for use in watery areas. So far they are still on! Just be sure first to clean the space on the wall and the back of the tile, and also grout the...

Thanks once again! But I am a little confused here. Has the original poster, Philo, invented the Liquidator, or is that a totally different piece of equipment? I am under the impression that is a totally different item that operates differently from the simple drip-flow apparatus described...

The original post stated "I fill it with 9 gallons of 10% liquid chlorine and 9 gallons of water mixed up" so he has mixed the two liquids. This will produce a homogeneous solution, not a suspension or dispersion that will stay mixed, just like other bleach-in-water products. I responded to...

There should (will) be no separation. This would be just like having a 5% bleach solution with 95% water. It will stay homogeneous. The higher percentages don't separate out (10%, 12%) on standing for several days or even much longer, so why would 5%.

Be sure to neutralize the MA first. Don't mix bleach with MA, ever!

Maybe someone with more knowledge will chime in, but these stains do not look like metal stains. It appears to be algae. MA may not remove them. We had a similar problem with stains from organic matter, leaves etc. although not as severe as yours is. MA did not budge them, so I neutralized it...

Of course I am well aware of that fact. "Whataboutery" does not change what we are discussing. The answer to your Coke question is actually no, but for reasons not relating to value for money. There are many alternative beverages that I can buy, which may or may not provide better value, but...

Thanks once again! I had already seen the paper, and I appreciate the links to old posts asking the same questions and the responses which are useful. Interesting that others also remark about the some reagents being listed as 99% water and the rest some unknown ingredients and the general...

No, just wanting to understand what is going on. Too much trouble to duplicate! Not to worry, I will still buy the kits. I expect they will stay in business. I am sure that details these tests can be found in most texts on water analysis and even used in HS or freshman college chemistry lab...

Thank you. Some are helpful, some are not. e.g. for R-0008, alkalinity reagent is listed as 95-99% dihydrogen oxide (!), and 0.1-5% components below reportable levels!. R-0004 also has 90-99% dihydrogen oxide and 0.1-5% trade secret, and 0.1-5% components below reportable levels. Are they...

Can anyone post the actual chemical content of the reagents and indicators used in the various tests recommended here? In addition the chemical reactions going on in the tests would also be very useful. Apologies if this is already posted somewhere. If so, a link or references would be...

The pool math calculator shows 495 ox of borax for 30 ppm in a 14,100 gal pool. This calculates out to 250 ppm or about 120 ppm sodium borate, accounting for the decahydrate. Can someone explain this apparent discrepancy? Thanks
