Circupool SWG: Corrosive effect to pool deck

[azeast]

I’ve owned the Circupool RJ60+ since July 2020. The system requires a higher salt level (ppm) than most other systems. Disclaimer: I have two golden retrievers that jump in and out of the pool often during summer.

In those two short years the water has had a highly corrosive effect on my pool deck’s (marbella pavers) and adjacent patio (artistic pavers). In total it will end up costing me about 30K to replace the damaged pavers. At that time I will cease using the system or else it will destroy the new pavers.

Hi! Welcome to TFP. I wonder why this happened. Would you mind telling us how you take care of your pool and what your current readings are? I’ve included some information below for your reading pleasure.

Do you have pictures of the pavers when they were new?

It's unlikely the damage was caused by salt. All pools have some amount of dissolved salt in the water, whether you use a SWG or not.

Are you keeping the dogs?

Lets us know in two years if damage continues.

Your stated that the Circupool RJ60+ requires a saltlevel higher than most other systems.
What is your salt level?

Most systems in North America recommend about 3000-3600 ppm.
The Circupool SJ series (not the RJ series) being one exception that comes to mind.

I have an RJ45+ and it runs just fine at 3000 ppm.

Post a full set of current testresults from one of the recommended test kits.

Chances are that something else besides salt is causing your paver issue.

az,

You assume it is the salt, but how do you know? I suspect that any pool water would have done the same thing. Cheap stone is cheap stone.

I have a rent house pool with flagstone coping. It started to shed thin layers almost immediately, but at the time it was a standard tablet pool. About two years later I converted it to saltwater. It has been saltwater for about 10 years and the flagstone is still shedding. It is no worse and no better. The saltwater made absolutely no difference. Cheap stone is cheap stone.

It is your pool, and you should do whatever you want, but I'd just as soon fill my pools in as have them not be saltwater pools.

Thanks,

Jim R.

For those who offered to help, thank you.

I’ve attached the pool’s chemistry and there is nothing that would have a corrosive effect.

The only viable explanation is that the Marbella pavers were of a poor grade as normally they should be more durable than most other patio surfaces.

I had minimal wear to the pavers for the 3 years after installing the deck and patio. The prlor SWG was from SGS. It required a salt level at least 1000 ppm less. Only when I installed the Circupool system did the patio begin deteriorated quickly.
