Bring in a sample and leave with a lab-grade analysis and a custom shopping list telling you exactly what your water needs.
Good water care starts with good information. Our Water Lab gives you a clear picture of what's happening in your pool or hot tub, so you're not guessing at what to add or how much you need.
And because we test your water, we can also help you choose the right products, understand how to use them, and make adjustments based on your next water test.
A few small details make a big difference in how reliable your results are.
Complex factors that require real lab equipment.
High phosphates can fuel algae growth and make water harder to keep clear. They can also contribute to deposits that may affect equipment performance and longevity over time.
Metals that can stain surfaces or tint water, often introduced through fill water or certain chemicals. High levels may indicate equipment damage and can also contribute to deposits and damage to heaters and other equipment over time.
Critical for salt system owners, where the wrong salt level means the system can't generate chlorine properly.
Water that's too soft can be corrosive to equipment; too hard, and it can leave scale on surfaces.
Cyanuric acid protects chlorine from sunlight, but too much can make your sanitizer far less effective.
Most samples come back needing at least one adjustment — here's what that usually looks like.
Chlorine, salt, or bromine below range usually means it's time for a shock treatment.
Water that's too alkaline can irritate skin, cloud water, and cause mineral buildup that can affect heaters and other equipment over time.
A common food source for algae, even when sanitizer levels look fine. High phosphates can also contribute to buildup on surfaces and equipment, affecting performance and longevity.
Too much CYA can make your chlorine less effective. The best way to lower it is usually to partially drain and refill your pool with fresh water.
Test strips and basic home kits can't measure everything, and their readings often aren't precise enough for manufacturers to accept for warranty claims.
Every test is logged to a digital record, giving you the documentation manufacturers ask for if a warranty claim ever comes up.
01Lab-grade equipment reads factors most test strips simply aren't built to measure accurately.
02Just bring in a sample. No charge, or need to book ahead.
03Just trusted water care, backed by data.
The questions we get asked most, answered honestly.
Important water chemistry parameters include sanitizer levels, pH, total alkalinity and calcium hardness. Depending on your pool or hot tub and its water-care system, additional factors may also need to be checked.
Pool water should be tested regularly, with more frequent testing during periods of heavy use or when water conditions change. We recommend coming in-store for a free water lab test once a month.
Cloudy pool water can have several causes, including improper water balance, low sanitizer levels, poor filtration or contaminants in the water. A professional water test can help identify whether the problem is related to your water chemistry and determine what adjustments may be needed.
Cloudy hot tub water can be caused by unbalanced pH or alkalinity, insufficient sanitizer, contaminants from bathers, or filtration issues. Testing your water is a good first step toward identifying the cause and getting your water clear again.
Green water is commonly associated with algae growth, which can occur when sanitizer levels are too low or water conditions aren't properly maintained. Testing the water can help determine the current chemistry and identify the appropriate next steps.
pH can change due to factors such as sanitizer use, adding water, rainfall, bather load and other changes in water chemistry. Testing your water helps determine whether your pH needs to be increased or decreased and whether other aspects of your water balance need attention.
Total alkalinity helps stabilize the pH of your pool or hot tub water. When alkalinity is outside the appropriate range, pH can become difficult to control and may fluctuate more than it should.
It's particularly useful to have your water tested when opening your pool, after adding fresh water, when you're having trouble maintaining proper chemistry, or whenever the water looks cloudy, green or otherwise unusual.
