This list can change. Manufacturers occasionally add or remove products from their MAP-protected lists. We update this page when they do, but the most accurate way to confirm whether a discount applies to a specific item is to add the item to your cart and try the code at checkout. If the code doesn't work, the item is excluded. If it does work, it's eligible.
Returns On Hazardous Materials
Some of the products we sell — primarily spa and pool chemicals — are classified as hazardous materials by the U.S. Department of Transportation (DOT). These items can't be returned to us by mail, even though we'd like to make returns easy on every product. This page explains why the rule exists, what's covered, and what your options are if you have unopened chemicals you no longer need.
The short version: We can't accept hazmat returns by mail (federal regulations prohibit it), but we can accept them in person at our Idaho Falls, Boise, or Twin Falls showrooms. If a product arrived damaged or defective, that's handled differently — call us right away and we'll work with the manufacturer on a replacement or refund.
SpaGuard Spa Phosphate Remover is a fast-acting liquid that immediately reduces high phosphate levels in spa and hot tub water. Phosphates are an invisible problem — you can't see or feel them — but at high levels they cause real trouble, the biggest being calcium phosphate scale that builds up on your equipment and surfaces. This product keeps phosphates in check so that scale never gets the chance to form.
Where do phosphates come from? They sneak in through fill water, lawn and garden runoff, and many common spa products and cleaners. As they accumulate, they create conditions for scale and can interfere with how well the rest of your water care performs. By stripping phosphates back down to a safe level, Phosphate Remover protects your spa's equipment from calcium phosphate buildup and helps your overall water care work the way it should.
It's a simple weekly addition — and an effective spot treatment when a test shows phosphates have climbed too high. Recommended phosphate levels in a spa are below 125 ppb.

SpaGuard® Brand FAQs
What is SpaGuard?
SpaGuard is a professional-grade brand of spa and hot tub water care products — sanitizers, shocks, balancers, and water enhancers — formulated specifically for spas rather than adapted from pool chemicals. The line is designed to work together as a complete system for clean, clear, comfortable water.
Who makes SpaGuard?
SpaGuard is part of the BioGuard family of water care brands, a long-established name in pool and spa chemistry. That backing means the formulas are professionally developed and tested, with a reputation built over decades in the industry.
What water care systems does SpaGuard offer?
SpaGuard supports three complete care methods: a chlorine system, a bromine system, and the Soft Soak TRIO system. Each is a coordinated set of products, so you can match your routine to the sanitizer you prefer.
What makes SpaGuard different from generic spa chemicals?
SpaGuard products are engineered for the unique demands of hot, agitated, heavily used spa water, and they're built to work together as a system. That coordination delivers more reliable, repeatable results than mixing unrelated single products.
What is ALEX water testing?
ALEX is SpaGuard's exclusive computerized water-analysis tool used by its dealers. A quick water sample produces a precise read on your spa's chemistry and a tailored recommendation, taking the guesswork out of what to add and when.
Why buy SpaGuard from an authorized dealer?
SpaGuard dealers are trained on the brand's products and water-care technology, so you get expert advice alongside genuine product. They can run an ALEX analysis, troubleshoot issues, and recommend exactly what your water needs.
About SpaGuard®
SpaGuard is a professional-grade line of spa and hot tub water care products engineered specifically for spas — not pool chemicals repackaged for a smaller tub. Built around a simple, proven approach (balance the water, sanitize it, shock it, and keep it clear), SpaGuard products are formulated to work together as a system across three care methods: chlorine, bromine, and the Soft Soak TRIO system.
Because the formulas are made for the unique demands of hot, agitated, heavily used spa water, owners get reliable, repeatable results with less guesswork. SpaGuard is also backed by a trained dealer network and ALEX water-analysis tools, so when a water issue does come up, there's an expert-tested path to fixing it. It's a trusted choice for anyone who wants clean, comfortable, sparkling water with a maintenance routine they can actually keep up with.
