Langelier Saturation Index (LSI) & Hydraulic Specialists

We Treat Swimming Pools Like Closed-Loop Hydraulic Vessels.

Guesswork test strips and splash-and-dash chlorine dumps ruin plaster, corrode heat exchangers, and drive up chemical bills. Poolcleanings Experts uses digital spin-disk photometry, vacuum/pressure gauges, and documented chemical logs on every visit.

What Symptom Is Your Pool Showing Today?

Select an active condition below to review the root hydraulic or chemical cause and our standard field protocol.

Root Cause: High Combined Chlorine, Early Filtration Bypass, or Calcium Carbonate Precipitation

Milky water is rarely solved by adding extra shock alone. When Cyanuric Acid exceeds 80 ppm or filter cartridges develop torn pleats, dead organic particulates remain suspended in the water column.

Our Story: Raising Pool Care From Casual Gig Work to Documented Water Science

Why Poolcleanings Experts abandoned test strips, flat-rate chemical shortcuts, and rushed 6-minute backyard stops.

Built to Solve the Three Biggest Failures in Residential Pool Service

Poolcleanings Experts was established after our lead equipment technicians noticed that over 70% of premature heater core failures, pitted plaster surfaces, and brittle vinyl liners were caused not by age, but by aggressive, unbalanced water chemistry from rushed weekly routes.

Many route operators focus only on making water look clear for 48 hours by over-dosing trichlor tablets—driving Cyanuric Acid (stabilizer) above 120 ppm while crashing pH below 7.0 during winter and spring. The water looks crystal clear while silently dissolving copper heat exchangers and etching cementitious finishes.

  • Year-Round Langelier Saturation Index (LSI) Accounting: We measure water temperature, calcium hardness, total alkalinity, pH, TDS, and CYA at every visit.
  • Dedicated Route Density Caps: Our route technicians service a maximum of 12 vessels per day—never 25+—ensuring full 35-to-45-minute mechanical and chemical care.
  • Transparent Repair Diagnostics: We repair component assemblies (capacitors, mechanical shaft seals, manifold grids, thermistors) whenever safe and economical before recommending whole-unit replacements.

Our Field Standards & Craft Identity

Every service truck carries LaMotte spin photometers, Taylor drop-count titration kits, ultrasonic flow meters, and factory OEM replacement seals for Pentair, Hayward, Jandy, and Raypak systems.

Equipment Repair & Hydraulic Head-Loss Diagnostics

Precision repair and hydraulic retrofits for pumps, gas & electric heaters, salt chlorine generators, valves, and automation systems.

Component-Level Troubleshooting Before Costly Replacements

Whether your variable-speed pump is throwing an over-current drive fault or your gas heater cycles off on a high-limit switch, our technicians test electrical load (amperage draw, microfarad capacitor ratings) and total dynamic head (TDH) before quoting repairs.

  • Variable-Speed Pumps: Viton shaft seal rebuilds, impeller clearing, motor bearing replacements, and DOE-compliant VSP installations.
  • Gas & Heat Pump Heaters: Thermal regulator replacements, manifold bypass repairs, igniter/flame sensor diagnostics, and pressure switch calibration.
  • Salt Chlorine Systems: Electrolytic cell acid washing, flow switch replacement, and board rectifier soldering/replacement.
  • Valves & Plumbing: Schedule 40 PVC manifold repiping, Jandy/Pentair 24V actuator replacements, and check-valve rebuilds.

Written Diagnostic Guarantee

Every equipment diagnostic visit includes a multi-point electrical and hydraulic inspection sheet. If you approve our repair estimate within 14 days, 100% of the initial diagnostic fee is credited toward the completed repair.

Green-to-Clean & Multi-Strain Algae Eradication

Turn stagnant, opaque swamp water back into a crystal-clear, biologically safe swimming vessel in 72 to 96 hours.

3-Stage Chemical & Mechanical Recovery Protocol

  • Stage 1 — Sub-Surface Debris Extraction & pH Lowering: Leaf raking of bottom sludge, reducing pH to 7.2 to maximize hypochlorous acid (HOCl) kill potency, and stripping orthophosphates.
  • Stage 2 — Breakpoint Shock & Wall Brushing: Stainless-steel or nylon wall brushing (matched to surface type), sustained SLAM chlorination based on CYA levels, and 24-hour circulation.
  • Stage 3 — Flocculation, Waste Vacuuming & Filter Teardown: Settling dead suspended biomass to the floor, vacuuming directly to waste, and deep-cleaning the filter media.

Black & Mustard Algae Remediation

Black algae forms protective waxy caps that resist standard chlorine levels, while yellow mustard algae re-infects pools via swimsuits and cleaning poles. We sanitize all pool tools and apply targeted trichlor scrubbing and sodium bromide treatments where appropriate.

Request Green Pool Recovery

Filter Deep Cleaning, DE Grid Teardowns & Media Recharge

Restore peak flow rates, lower pump electricity consumption, and eliminate microscopic particulate bypass.

Why Rinsing With a Garden Hose Isn't Enough

Sunscreen oils, body lotions, and calcium scale bind to polyester cartridge pleats and DE fabric grids. Over time, water channels through the path of least resistance, returning unfiltered debris to the pool while spiking tank pressure.

  • 4-Cartridge System Cleanings: Complete disassembly, enzymatic degreasing bath, high-volume pleat flushing, tank O-ring lubrication with PTFE silicone, and air-relief valve inspection.
  • Diatomaceous Earth (DE) Grid Teardowns: Full manifold extraction, inspection for torn stitching or cracked plastic spines, cleaning, and exact weight recharging.
  • Sand & Activated Glass Media Changes: Lateral assembly inspection, vacuuming out channeled old sand, and recharging with #20 silica sand or sub-5-micron activated crushed glass media.

Recommended Service Intervals

Cartridge and DE filters should be disassembled and deep-cleaned every 4 to 6 months, or whenever clean operating pressure rises 8–10 PSI above baseline.

Schedule Filter Teardown

Electronic Leak Detection & Plumbing Pressure Testing

Pinpoint hidden underground suction/return line leaks, skimmer throat separations, and main drain hydrostatic valve failures.

Non-Invasive Acoustic & Pressure Isolation Workflow

  • Evaporation vs. Structural Differential Verification: Calibrated static vs. dynamic water-loss testing to determine whether water loss occurs primarily when the pump is running or off.
  • Plumbing Line Pressure Rigging: Rubber expansion plugging of skimmer, main drain, cleaner, and return lines followed by regulated air/water pressure decay testing.
  • Acoustic Hydrophone & Deck Geophone Listening: Sub-surface microphone scanning to detect the exact frequency of escaping water beneath concrete, pavers, or travertine decks.
  • Structural Dye Testing: Precision syringe dye testing around light niches, return eyeballs, fiberglass steps, and plaster cracks.

Comprehensive Leak Location Report

Every leak detection appointment includes deck chalk/tape marking of the exact anomaly location, photographic documentation, and a written repair quote.

Calcium Scale Removal & Kieserite Tile Bead Blasting

Safely erase white evaporative calcium lines from ceramic, porcelain, glass, and natural stone waterlines without harsh pumice scratching.

Why Kieserite (Magnesium Sulfate) Outperforms Glass Bead & Soda

  • Mohs Hardness 3.5 Safety: Softer than tile glaze (Mohs 6.0–7.0), meaning it strips stubborn calcium carbonate and calcium silicate deposits while leaving ceramic and glass finishes unscathed.
  • Water-Soluble & pH Neutral: Unlike silica sand or glass beads that require full pool draining, Kieserite dissolves cleanly or vacuums out easily without spiking pH like sodium bicarbonate (soda blasting).
  • Post-Blast Sealer & LSI Re-Balancing: After blasting, we apply a breathable penetrating stone/tile sealer and adjust pool LSI so scale does not immediately reform.

Linear-Foot Transparent Pricing

Quoted cleanly by perimeter linear footage after inspecting tile material and scale thickness (carbonate vs. gray silicate scale).
