Thank you chem geek. Which do you think is better(convenient etc...) the peristaltic pump or the liquidator from Hasa? Which brand peristaltic pump is the best and does either system also handle acid? Thanks again

I just found this- "Switching to an unstabilized chlorine source will require either daily chlorine additions yourself (usually in the evening--it's really not a lot of work) or adding some type of automatic feed system designed for either sodium hypochorite (liquid chlorine or bleach) such as a peristaltic pump system or cal hypo (usually not readily available for residential pools at a reasonable price) or a SWCG (high initial cost but offset by the convenience factor in the long run)." Any more info on cal hypo and can it be added automatically and what is a SWCG? Thanks again.

I hope it is OK to ask questions without reading every topic/post first. I am new to the forum but wanted to jump right in... if that is ok? Our pool is at a weekend location so it often go 5-7 days without attention. As I am not able to add shock often, I rely on the 3" tabs in an auto-tube(whatever it is called) on an ongoing basis. Because of this it is a constant challenge to keep my cya low enough. It is my understanding there is no 3" tab without stabilizer but I read this at the forum- "Bleach is sodium hypochlorite, an unstabilized chlorine and does not add CYA since it does not contain any. The same is true for the other inorganic chlorine sources, calcium hypochlorite, lithium hypochlorite, and gas chlorination (normally used in commercial pool installations)." Does calcium hpochlorite or lithium hypochlorite come in a form that I could use in my 3" tab dispenser or is there an automated dispenser for either one that I could add to my pool. If not, does anyone have any suggestions for a way that I could automatically add chlorine to my water on an ongoing basis without raising the cya. Thanks in advance for any help!
