So how come there aren't a LOT of sick people?

Before I found this site, I followed that 1-3ppm no matter the CYA, I live in Mass. and in May/June the water was pristine crystal clear because the water temp was in the 60's/70's and then when the water started to warm up in July then the algae started. Water never turned green, just all over the liner, in the filter, even the clear view to see the backwash had green in it. I didn't understand what I was doing wrong. I was using gallon after gallon of Algaecide, still green. Then I found the chart on this site and 3 years later and have never had algae again. I use pucks to chlorinate in a floater, bleach to shock and have switched to Baking Soda and Borax.

This makes no sense to me......

I thought the reason concluded behind SWG companies all suggesting 80ppm CYA was that you could maintain a lower chlorine level.

Does this chart state that SWG owners need at lease 5ppm Chlorine to have a safe pool? I dont think my SWG will generate that much.

My understanding is that it's different for SWG pools, as the cells are basically super chlorinating the water continously (as long as they're running), so less of a residual is needed in the pool.

it makes for an informative read . And even if I never read anything about CYA, I know whats working in MY pool. Before I found this site , I couldnt figure out why my pool was such a pita. When I learnt to deal with the high cya , the pool looks great , less work and more fun. dont need to prove anything else to me

Great article, thanks!

I use the liquid bleach regimin too after visiting this site, and I also have great results. Just trying to understand a bit more of the why.

I work in a hospital laboratory and see peps that are sick from pools. The reason you don’t hear about it is because the environmental source of infections are hard to identify. I would venture most middle and outer ear, eye infections, and wound infections in families with pools are pool related. I have seen skin infections caused by Pseudomonas from pools. I have seen respiratory infections form pools and spas. I read an article a few days ago about pathogenic E.Coli transmitted by pool water. Its there you just don’t hear of it very much. I feel that if you are seeing algae you have a higher risk from pathogens in the pool as well. If our immune systems are functioning well we can fight off mild attacks but in the young and elderly populations are at higher risk.

SWGs are different. See this thread:

I love this observation.
