What AquaChek does

AquaChek is a consumer and professional products brand specializing in pool and spa water testing, operating as a subsidiary of Hach (a major water quality instrumentation company), itself part of Veralto, a global water technology group. The company designs and sells colorimetric test strips and test kits covering more than a dozen parameters — free and total chlorine, bromine, pH, total alkalinity, cyanuric acid, total hardness, salt (sodium chloride), iron, phosphate, nitrate/nitrite, borate, copper, MPS, peroxide, and biguanide — organized into three tiers: a homeowner line segmented by sanitizer type, a professional line (Silver 7-in-1, Pro, Pro II, plus specialty tests), and complementary digital tools (Water Balance, Volume, Langelier Saturation Index, and unit conversion calculators). Core technology is colorimetric dip-and-read chemistry packaged in flip-top dispensers, supplemented by TruTest digital readers for automated color matching and the Select Connect Kit, which pairs a 7-in-1 strip with a free mobile app that uses photo capture to scan strips and deliver personalized water treatment recommendations.

The business model is primarily a one-time-purchase consumer products line with built-in recurring demand from refill strips for both consumers (e.g., Select Connect refills, TruTest refills) and professional operators. Pricing is not publicly disclosed; products reach end users via Amazon's global storefront, a network of 255+ authorized retailers accessible through a radius-based "Find a Retailer" locator, and a pool/spa dealer channel serving service professionals. Go-to-market combines product-led growth (free app, free educational content, free calculators driving top-of-funnel engagement) with channel partner distribution and content marketing through Water Testing 101 guides and SEO. AquaChek holds four registered trademarks (AquaChek, Select Connect, TruTest, Pro II), a registered compatibility partnership with Baquacil for biguanide pools, and operates from Loveland, Colorado under Hach/ETS corporate ownership with Veralto overseeing privacy and compliance functions.

Scale indicators1 record

Recent moves6 records

Expansion highlights5 records

Others

• Hach Company: Hach is AquaChek's parent company and a global leader in water quality analytical instrumentation for industrial and municipal markets. While not a direct consumer competitor, it provides the technological backbone and distribution infrastructure that AquaChek leverages.

Broad incumbents

• Hayward Holdings: Hayward is a leading pool equipment manufacturer with its own OmniLogic and pool automation platforms that include water chemistry monitoring. It represents a broad incumbent moving into the connected pool testing category from an equipment-installer angle.
• Pentair: Pentair is a major pool equipment manufacturer that has expanded into smart water monitoring and chemical management. While its core business is pool equipment, its connected pool ecosystem competes with AquaChek's digital/app-enabled testing for the same homeowner customer.

Direct peers

• Poolmaster: Poolmaster is a major pool & spa accessories brand that sells its own consumer test strips and pool maintenance kits through mass retail and pool supply channels. It competes with AquaChek at the entry-level consumer tier, especially in big-box and pool specialty stores.
• LaMotte Company: LaMotte has manufactured water analysis products since 1919, offering pool & spa test kits, reagents, and instruments. Its product range (ColorQ, Pool & Spa Test Kits) overlaps directly with AquaChek's test strips and digital readers across both consumer and professional segments.
• GLB (Great Lakes Biochemical): GLB is a pool and spa chemical brand that sells its own line of consumer and professional test strips and kits under the Algae-Bomb and pool care umbrella. It competes with AquaChek for shelf space at pool retailers and on Amazon in the same sanitizer-system test categories.
• Taylor Water Technologies: Taylor Technologies (Taylor Water Technologies) manufactures professional and consumer pool/spa water testing kits, including the widely used K-2000 series and drop-test kits. It competes directly with AquaChek's Pro and Silver 7-in-1 product lines for both service professionals and DIY consumers.

Emerging players

• pHin: pHin offers a smart pool and hot tub monitor with chemical dosing recommendations delivered through a mobile app. It is an emerging direct competitor in the smart, app-connected water testing space that overlaps with AquaChek's Select Connect product positioning.
• Sutro: Sutro makes a smart connected pool water monitor that provides real-time chemistry readings via a mobile app. It represents the emerging category of IoT-enabled continuous pool monitoring that could disrupt manual test strip usage — a key strategic concern and adjacence for AquaChek.

Regional players

• Baquacil: Baquacil is a biguanide-based pool sanitizer brand with which AquaChek Blue is explicitly compatible. While Baquacil focuses on chemical sanitizer sales rather than test strips, the brand represents the alternative sanitizer ecosystem where AquaChek's Blue product competes for testing share.
