I’ve had a spa in the past, and the chemicals were always a challenge to get right. SilkBalance is so simple to maintain it’s not even a chore. Plus, the water feels great–it’s clean, fresh, and not like typical pool or hot tub water. We’ve always found a hot tub relaxing, but with SilkBalance, it’s the first time we’ve thought of it as refreshing, too. I’ll never go back to fighting with tablets and scoops of chemicals!
