Hi, I have read only good things about Aquabright - but only up until 2019 or so. Does anyone have some experience with longer usage? Will it last 10 years (or more?) I am seriously considering it for a concrete pool built in 2020 which has been painted twice already - last time to disastrous results (bubbles!) current pool man wants to put a liner in but I'm not a fan and price is not cheap at EUR 10,400. Also looking at resin at 12,000 and then aquabright at 17,000. I am very willing to pay if it is as fabulous as promised. The installer has quite a few years of experience so this does not appear to be a concern. Thanks for any input!
