Hot tub ownership should be all about relaxing, unwinding and enjoying your backyard oasis. But if you’ve ever struggled with confusing water chemistry, unexpected scum or skin irritation after a soak, you know it can sometimes feel like anything but relaxing. That’s where Serum SuperSoft steps in — a simple, science-backed water care system designed to make your hot tub feel luxurious and stay clean with minimal effort.
Whether you’re a new hot tub owner or a seasoned soak enthusiast, here’s why Serum SuperSoft is quickly becoming a must-have for spa lovers who want soft, sparkling water and a stress-free maintenance routine.
What is Serum SuperSoft?
Launched in late 2024 by Serum Watercare, SuperSoft isn’t just another bottle of spa chemicals — it’s a complete water care system built on years of research and real customer feedback. SuperSoft packages three of the company’s most effective products into one easy-to-use solution:
- Cashmere by HTS Turbo — a borate-based product that makes your water feel silky and soft
- pH Down — helps keep your water balanced
- Total Maintenance — an EPA-registered secondary sanitizer that actively kills bacteria and biofilm
“It actually kills bacteria and other pathogens,” says Bill Meyer, vice president of sales and marketing at Serum Watercare.
In other words, SuperSoft makes your spa water feel incredible and helps prevent the buildup of harmful gunk you can’t see.
Why water chemistry is such a big deal
As much as people love the high-tech jets and glowing lights on modern hot tubs, nothing ruins the vibe faster than cloudy water or itchy skin. According to Mark Henderson, president of Serum Watercare, this is where many hot tub owners get tripped up.
“When you put that tub in the backyard, water chemistry takes center stage,” Henderson says. “All the other bells and whistles mean nothing if you can’t get the water right.”
That’s exactly why SuperSoft exists: to simplify spa care and help you enjoy your tub more, with less hassle and fewer service calls.
Fun + functional: Meet the cutest spa accessory you didn’t know you needed
Beyond SuperSoft, Serum Watercare has also made a splash with its line of oil-absorbing sponges — and trust us, these aren’t your average scum balls. They come in vibrant, plush designs like tropical fish, turtles and manta rays, making them fun for families and eye-catching in any spa or pool setup.
Henderson, who used to work in the toy industry, brought that playful energy into the product line. “We weren’t sure the turtle would sell,” he laughs — but it quickly became a top seller.
Not only are these sponges adorable, but they’re also:
- Machine washable
- Long-lasting (with a three-year warranty!)
- Available in over 20 designs
- Perfect as gifts
Consumers love them because they’re just fun. They work hard to keep your water free from oils and grime, and they look good doing it.

Products like SuperSoft make hot tub ownership easier, more enjoyable and more sustainable — for everyone.
