Sanitization Systems

[Risky Roscoe]

Straight up sanitization system for my pool

So many options every one has a angle and an opinion
.I am a capable guy but this still confuses me ! after much research
My question is and I hope to get some clear precise perspective if possible thank you
Approx 100,000 litre pool above ground concrete pool 18m x 4.5m - low bather load
Due to a number of reasons primarily water considerations and fire hazards salt is out
as any water may have to be utilized in different ways on the property - salt ( even low salt water )
cannot be run through the existing water infrastructure
Rural bush location - heavy vegetation but not within 15 meter of pool area
Southwest Australia - sort of a San Diego climate

Chlorine in general not a preferred option due to skin sensitivities with chlorine
tPlease may i get some houghts on low chlorine + uv sanitisation -
I are lead to believe this can be achieved effectively with the water basically feeling fresh and clean and odorless
unless a chlorine dump happens i,e probe goes wrong etc
1st choice is a naked system ( copper silver ) + uv - but so many varied opinions on these types of sanitation systems
but I can control most of the copper issues by rotating water into a holding tank if adjustment is required and replacing water

So please from any experts within the industry what would they do in my situation

Thanks in advance Risky

The naked system is a low salt chlorine/metal iron system. Copper and silver can/will cause staining. Copper or silver can’t effectively sanitize on there own and neither provide any oxidation which is why naked system incorporates the chlorinator. I think the naked system runs at 1200ppm salt. If you run a naked system you will need the pH control. If it fails you increase your risk of staining. Many have, FB is littered with the stories.

Pools need pH management, pool acid will add salt. Tap water adds salt. It’s not uncommon to have a fresh water pool at 1000ppm salt or higher.

Why would you not want salt? Salt pools are nowhere near ocean water. About 10% of it.

Why would you not want chlorine? Or rather, why would you not want a safe sanitized pool?

We have skin sensitivities and have adopted the TFP method for over 10 years without issue. Following the TFP method your pool has less active chlorine then tap water (town water supply).

Welcome, and note that a salt pool is a chlorine pool. There is no difference except for where the chlorine is made. Not sure of your exact reasons but many people think a salt pool is like the ocean, but it’s nowhere even close and there’s really no reason not to get your chlorine from the salt as it’s the easiest way to do it. In addition, many people think that they have chlorine allergies because of previous pools that they have experienced, which were very poorly sanitized. Once you manage the chlorine properly, it’s very rarely a problem for anyone to have chlorine allergy.

Maybe elaborate on some of your considerations and others can advise further. The key to managing any pool water well is having a good test kit. Poor test kits and free pool store testing have led thousands of people into frustrating pool experiences.

Do a search for copper and metal staining. It’s a mess and not something we’d ever advocate even if it worked well (hint: it doesn’t work well).

If you live in a climate like San Diego and you are concerned about water usage (I live in the Sonoran Desert … water conservation is always a top priority), then a salt water chlorine generator is them only viable option (as well as using cartridge filters to avoid backwashing). My property is all native desert plants and they could care less if I dump pool water on them. An SWG system allows you to generate sanitizing chlorine without adding other components (like calcium, minerals, or cyanurates) that force you to do water exchanges.

You get enough UV light from the sun in an outdoor pool so the dinky bulb in a small contact tank is like spitting in the ocean … useless.

Minerals like copper and silver really only act as algaecides at concentrations close to their precipitation limits and they barely affect most nasty pathogenic bacteria. Silver really only works as a disinfectant when it is paired with a powerful oxidizer (like peroxides) AND the water is held at high temperature (hot tub type temps at 40C). Under normal outdoor pool conditions, silver ions are useless. Zinc is ineffective and copper is really only an algaecide. None of these systems work well in the long run and you’ll be constantly dumping pool water to keep staining at bay.
