20X40 inground kidney concrete pool SWG Hayward pump and filter Solar panel system (independent pump from pool filter) My pool water chemistry is fine according to the pool store test. But my pool is still cloudy. I had a calcium harness issue as well as a high PH issue. That has been resolved, but still have the cloudiness. I read in another area that my SWG can cause hydrogen bubbles to enter my pool. My question is.........could my SWG be my issue, or is it possible I have an air leak somewhere in my lines? I have not performed a test to figure out if I am losing water, but it does seem like the water loss is more than evaporation. I also have noticed that I lose my water level in my pump skimmer when I shut my pump off. It doesn't appear to be a gasket problem, but is it? Any thoughts? Justawildchild

[EDIT] Apparently, I wrote this as waterbear was writing his post above. [END-EDIT] This is normally true for manually dosed pools, but we found out that there is a significant increase in protection of chlorine from the UV of sunlight somewhere in the range of 50-80 ppm. This is above and beyond the theoretical protection predicted from the equilibrium chemistry and my best guess is that it is a shielding effect of the CYA protecting the lower depths (though this requires a lack of mixing near the surface). We discussed this issue in this long thread and then some experiments were done to see if the cause had anything to do with the SWG itself (it didn't) in this post. In commercial pools, a maximum stabilization at around 20-30 ppm is seen because the higher bather load has a larger chlorine loss than that from sunlight in that CYA range so any increase in CYA doesn't seem to do much good. This is not the case in residential pools. The main reason to have a higher CYA level in an SWG pool is to allow for lowering of the SWG output since that reduces the production of hydrogen gas bubbles in the SWG which reduces aeration which pulls carbon dioxide out of the water and causes the pH to rise. I was surprised by this finding and had to eat crow about a theory I came up with to explain it that turned out to be dead wrong as Mark's experiment proved. Richard Does this mean that my SWG is causing the air bubbles coming out of my return jets, and this is because my stabilizer levels are too low?

I'm sure people have asked but I may not be typing in the right keywords. So hopefully we can revisit this again. What are other cheaper alternatives to many of the pool chemicals that we use. And what are the cost effectiveness of these products? I know that we can use some everyday products but they may be less potent and end up buying more. What products are there? Thanks Justawildchild
