Last year chem geek gave a detailed analysis of the chemistry of the bleach solution on top of the Liquidator. This solution is enriched with chlorine more than the pool water, although its concentration there is a lot lower than that of the bleach at the bottom. Also, the pH there is supposedly higher than that of the pool water.
The analysis predicted that adding borates may eliminate WS (insoluble Calcium salt) settling on the Liquidator tubing and flow indicator. This is indeed what happened in my pool system, when I added borates this year. However, borates was not the only parameter that was changed this season. I also changed this year to 12% bleach as compared to 6% last year, when I had WS. Someone indicated recently that 12% bleach may help to eliminate the WS. I wonder if this is true, and if it is, what may be the mechanism? Don’t we expect higher pH at the top solution for 12% bleach as compared to 6%?
