FreshWater Spa Vac
The FreshWater Spa Vac is a portable, manual hot tub vacuum that removes debris from the bottom of your spa shell without draining a drop of water. Leaves, dirt, sand, hair ties, pebbles, the occasional bottle cap — anything that's fallen in and settled out of suspension that your cartridge filter isn't going to catch — gets sucked into the vacuum's collection chamber while you stand outside the spa with the wand. Empty the chamber, and you're done.
This is the tool that fills the gap between two things every spa owner already has: a filter cartridge (which catches suspended particles being moved by circulation) and a skim net (which catches floating debris on the water surface). Neither one helps with anything that's settled to the bottom of the shell. That's the Spa Vac's job — and once you've done it for the first time, you'll be surprised what's accumulated on your spa floor.
For most owners, three situations are when the Spa Vac earns its place in the maintenance routine:
- Between drain-and-refill cycles — quick monthly cleanup to remove what's settled out since the last full water change
- After windy weather, storms, or fallen leaves — outdoor spas accumulate environmental debris that floats briefly then sinks
- Before guests arrive — a clean-looking spa floor matters when others can see down to the bottom
The Spa Vac is the kind of tool that doesn't get talked about much because chemistry pages dominate spa maintenance conversations. But owners who use one tend to use it often — and owners who don't have one tend to either drain more often than necessary or live with debris on the bottom of their spa.

FreshWater® Brand FAQs
Do I have to own a Hot Spring or Caldera spa to use FreshWater products?
No. FreshWater chemicals, test strips, and most accessories work on any residential hot tub or spa, regardless of brand. The FreshWater Salt System and FreshWater IQ Smart Monitoring System are the exceptions — those are designed specifically for compatible Watkins Wellness spas (Hot Spring Highlife and Limelight, Caldera Utopia and Paradise). Everything else in the line is universal.
How is FreshWater different from other spa chemical brands?
Most spa water care brands are formulated by chemical companies and sold across hundreds of unrelated spa models. FreshWater is formulated by the same engineering team that designs Hot Spring and Caldera hot tubs — so the chemistry is built to match what real spa equipment actually needs. Dosing recommendations, concentration levels, and pH targets are calibrated against working spas, not a generic spec sheet. That precision tends to mean less chemical waste and fewer balance problems over the life of a fill.
Can I mix FreshWater products with other brands like Leisure Time or SpaGuard?
In most cases, yes — but with one important caveat. Don't mix sanitizer systems. A chlorine spa should stay on chlorine; a bromine spa should stay on bromine. Mixing sanitizer chemistries can create unwanted byproducts and unstable readings. Balancers (pH, alkalinity, calcium hardness) and supporting products like defoamers, clarifiers, and stain & scale defenders are generally compatible across brands. When in doubt, call us or bring a water sample to one of our showrooms before mixing chemistries.
How long do FreshWater chemicals last in storage?
Unopened, most FreshWater liquid and granular chemicals have a shelf life of 1 to 2 years from manufacture when stored cool, dry, and out of direct sunlight. Test strips last about 1 to 2 years if the bottle stays sealed with its desiccant pack between uses. Chlorine-based products lose strength faster than balancers, so rotate stock — oldest first — and avoid buying more than a single season's supply at a time. The expiration date is printed on the container.
Are FreshWater products safe for sensitive skin?
When dosed correctly and the water is properly balanced, yes. Most skin and eye irritation in hot tubs isn't caused by chlorine or bromine itself — it's caused by chloramines(used-up sanitizer that hasn't been oxidized) or by water that's outside the proper pH range. Owners with sensitive skin often do well on the FreshWater Salt System (lower active chlorine residual) or on a mineral-supported chlorine program. If skin irritation is an ongoing issue, see our Eye/Skin Irritation Problem Solver page.
Can FreshWater chemicals be returned by mail?
Some can, some can't — it depends on whether the product is classified as hazardous material (hazmat) by the U.S. Department of Transportation. Test strips, defoamers, calcium removers, clarifiers, and most balancers are non-hazmat and can be returned by mail. Chlorinating granules, bromine products, and pH/alkalinity down (a regulated acid)are hazmat and cannot ship back by mail under federal law — but they can be returned in person at any LTI showroom. See our Returns on Hazardous Materials page for the full list.
About FreshWater®
FreshWater® is the water care brand from Watkins Wellness — the parent company of Hot Spring, Caldera, and Freeflow Spas, and one of the largest manufacturers of premium hot tubs in the world. Watkins has been engineering spas and water care chemistry for over forty years, and FreshWater is the line they developed specifically to keep their own equipment running clean, clear, and properly balanced.
What that means for owners: FreshWater chemicals, sanitizers, test strips, and accessories are formulated and dosed for the same shells, jets, heaters, and circulation systems Watkins builds. Active ingredients, pH targets, and concentration levels are calibrated against real spa equipment — not generic pool chemistry repackaged for hot tubs. The result is a product line that works as well in a Hot Spring or Caldera spa as it does in any other residential hot tub on the market.
The FreshWater catalog covers everything from routine maintenance to advanced water care technology:
- The FreshWater® Salt System — a sanitizer system that automatically generates chlorine from a salt cartridge, lasting up to a full year between water changes
- The FreshWater® IQ Smart Monitoring System — sensor and controller that read chlorine, pH, and salt levels and display them on the spa's topside control
- Sanitizers and sanitizer support — chlorinating granules, Ag+ Silver Ion Sanitizer, mineral cartridges
- Balancers — pH/Alkalinity Up, pH/Alkalinity Down, calcium boosters
- Water clarity and care — clarifiers, defoamers, stain & scale defenders, phosphate removers, Vanishing Act calcium remover
- Testing — 5-Way Test Strips, Salt Test Strips, Phosphate Test Strips
- Start-up kits and bundles — pre-portioned chemistry packages for fresh fills and new spa setups
Leisure Time Inc. is an authorized FreshWater dealer and stocks the full line at our Idaho Falls, Boise, and Twin Falls showrooms. Online orders ship nationwide, and water samples can be dropped off at any of our showrooms for free professional testing if you'd like a second opinion before you dose.
