Stuck with a pool that reads sky-high stabilizer and can’t be drained? We break down a step-by-step plan to bring control back fast: how to verify overrange CYA with simple dilution tests, when to abandon trichlor, and the exact chlorine targets that keep algae at bay while CYA slowly falls. You’ll hear the practical math behind Bob Lowry’s 7.5 percent rule and a weekly dosing rhythm that works for a typical 15,000-gallon pool without expensive gimmicks.

We also tackle metal management with a clear take on copper testing. Need a quick yes/no? Strips are fine. Need precision to avoid stains or diagnose issues? Photometers like PoolLab 2.0 and LaMotte ColorQ 2X Pro 9 are worth the investment. We call out a common pitfall with chelated minerals in PoolRx that make readings swing and explain what to watch instead so you don’t chase phantom numbers.

On the gear side, we solve the frustrations that waste your time. If a Polaris 280 tail is soaking your deck, the TailSweep Pro is the simple diffusion fix that ends the spray. Cracked unions on salt cells or filters? Split quick couplers snap over existing plumbing so you avoid cutting and long repairs. Wrestling with a Hayward Navigator that keeps eating parts? We lay out how to seat the A-frame correctly, tighten pods, and when to finally retire a parts hog that’s beyond saving. And for those dreaded seized wall fittings with broken tabs, we share a counterintuitive trick: insert the quick disconnect to fill the hollow, then twist with channel locks—clean removal without cracking the body, followed by fresh Teflon for a future-proof reinstall.

• Verifying high cyanuric acid with dilution tests
• Stopping trichlor and shifting to cal hypo plus liquid chlorine
• Holding 15 ppm free chlorine with high CYA using Lowry’s ratio
• Slow dilution via equipment spigot and autofill
• Copper testing: when strips suffice and when to use photometers
