Muriatic acid distribution methods

Here is the thread that talks about the 'slug method' and here is a link to the paper that debunks it!

I pour it in front of the deep end return with the pump running.

Gargle , rinse , swish and spit......

Speaking of distribution methods, has anyone seen or heard of this....

If this thing really works and does not damage anything where the Acid enters the pool, then I'm sold. Talk about a maintenence free pool!! Just about the only thing I have to to most of the summer is add acid to keep ph in check

Controllers with electrodes and automatic dosing wiith peristaltic pumps has been used on cmmercial pools for years. In fact, the Pool Pilot Total Control system includes such equipment. The main disadvantage is the price. If you have the extra $1500 lying around to install it and have the money for maintenance to keep it running properly then go for it.

Also keep in mind that the website is incorrect in stating that the source of the rising pH from chlorine generators is from the basic/alkaline chlorine generation. As we know, the usage of chlorine is acidic and exactly compensates for the initial basic/alkaline nature of chlorine production so the net result is pH neutral (this post describes the chemistry).

Since the true cause of pH rise in pools with chlorine generators is the hydrogen gas bubbles that aerate the water pulling out carbon dioxide that then gets outgassed into the air, the use of this automatic acid dosing product will result in a reduction in Total Alkalinity (TA) over time (just as periodic manual acid addition would). That's probably less of a hassle as the TA drops relatively slowly, but it is something to test periodically and adjust.
