Pool safety , what do you use ?

We are moving to a new house that has the most amazing pool . I have a 22 month old and I'm 6 months pregnant , so I'll soon have a newborn .

I like the idea of these poolnets because they don't ruin the look of the pool . They are expensive to install but I really can't find any reviews on them .

Second pic shows a fence , which I kinda hate how it looks but safety is my priority .

Or do you use a pool alarm ?

I'll always keep an eye

On my kids regardless but I've heard so many horror stories I want to be careful

Just wondering what others used that are safe without ruining the look .

Thanks , hope I don't get judged for carrying about the look of the house . Safety is top priority .
