Waters Choice will turn your spa care from confusion to simple overnight. The first thing you will notice is that instead of this little tote full of products for your spa, we have one bottle, (if you have high PH and hard water you will need to adjust your PH). Instead of checking your spa once, twice or even three times a WEEK we ask you to check your spa twice a MONTH. Like changing water? Instead of two to six times a year we recommend changing your water once a year.
