Andrea Unfiltered – Stop Using Test Strips Like They Know What They’re Doing

Pool Pros text questions here

This isn’t a calm episode.
This isn’t a polite episode.

This is Andrea… slightly unhinged… walking straight into the chaos of how people are actually taking care of pools—and calling it out.

From test strips that don’t tell you what you think they do… to calcium myths that refuse to die… to phosphate treatments that turn into unnecessary full-blown disasters—this episode is a reality check for anyone still guessing their way through water chemistry.

And underneath the sarcasm and frustration… there’s something important:

👉 Most bad pool care isn’t complicated
👉 It’s just built on bad habits, bad info, and shortcuts

This episode strips all of that down and replaces it with something better:

Understanding what actually matters.

⚠️ WHAT ANDREA GOES AFTER

Test Strips
→ They don’t test calcium hardness
→ They test total hardness
→ And that difference matters more than people realize

Calcium Hardness Myths
→ “It doesn’t matter in fiberglass or vinyl”
→ Wrong
→ It still needs to be in range—even if the consequences look different

pH Obsession
→ Chasing 7.4 constantly?
→ You’re creating your own problem through aeration and rebound

Cyanuric Acid Confusion
→ It protects chlorine… until it starts limiting it
→ And yes, there’s actual math behind what your chlorine level should be

TDS Panic
→ “Drain it, TDS is high!”
→ Based on… what starting point?
→ Because without that, you’re guessing

Phosphates (the hot take)
→ Not a problem… until they are
→ And overcorrecting them can create more work than the problem itself

🔥 THE MOMENTS THAT HIT

“Phosphates are not a problem… until they’re a problem.”

“If you’re testing while algae is present… you’re probably getting a false low.”

“You don’t even know your TDS limit… unless you know where it started.”

🧪 WHAT YOU ACTUALLY LEARN

• Why calcium hardness still matters in every pool
• The difference between total hardness vs calcium hardness
• Why chasing pH can make your water harder to control
• How CYA changes chlorine effectiveness (with real ratios)
• Why TDS is often misunderstood—and misused
• A smarter, low-impact way to manage phosphates
• How bad testing technique leads to bad dosing decisions
• Why your test kit might be lying to you (and how to fix it)

⚠️ REAL TALK

If your testing is wrong…
your dosing is wrong.

If your dosing is wrong…
everything that follows is wrong.

And most of the time?
It started with something as simple as:

👉 Holding the bottle at the wrong angle
👉 Using the wrong test method
👉 Or trusting a strip that doesn’t measure what you think it does
