Salt Cell Problems? Here’s What’s REALLY Going On

Image
Saltwater pools still run on chlorine, and the heart of the system is the salt chlorine generator cell. When the salt cell starts failing, the pool can go from clear to cloudy fast, and many owners misdiagnose the problem as “low salt” instead of low chlorine production. A key reason these parts are expensive is construction: titanium plates coated with precious metals like ruthenium or iridium. That coating is what makes chlorine generation efficient, and it is also what gets damaged by neglect, scale, or harsh cleaning. For pool maintenance and pool service professionals, keeping a cell alive means understanding both equipment limits and water chemistry, not just turning the output knob up and hoping. Sizing is the first leverage point. Many builders undersize a salt cell, leaving no production margin during heat waves, heavy bather load, or long sunny days. Looking at chlorine production rates helps: a Pentair IC15 produces about 0.60 lb/day, an IC20 about 0.90 lb/day, an IC40 about...

Cal Hypo Tablets in Real Pool Situations

Image
High cyanuric acid (CYA) is one of the most common reasons a pool suddenly becomes hard to keep clear, even when you “keep adding chlorine.” The key is that stabilized chlorine sources like trichlor tablets continuously add CYA, and that stabilizer does not evaporate out of the water. Trichlor is convenient, but it carries a built-in side effect: roughly half the tablet’s weight becomes cyanuric acid. If a pool is already sitting around 100 to 150 ppm CYA, every additional tablet makes the chlorine less effective, forcing higher free chlorine targets and creating a cycle of chasing chemistry. For many pool service pros and homeowners, the question becomes how to reduce CYA without a large drain, especially where water restrictions make partial drains difficult or unpopular. Cal hypo tablets are often suggested as an alternative because they add chlorine without adding stabilizer. That makes cal hypo tablets a practical way to pause CYA growth while you work down the stabilizer level ov...

Low-Chlo: The Future of Pools with Founder Todd Guarino

Image
Pool owners and pool service professionals are stuck between two frustrating options: run higher chlorine than anyone really wants to swim in, or buy a salt system that promises “softer” water while still functioning as a chlorine generator. The core idea in this conversation is simple but disruptive for pool maintenance: you can keep a residential pool sanitary with far less free chlorine by letting minerals do most of the sanitation work and using chlorine primarily for oxidation. That shift matters because it reduces the harsh, corrosive feel many swimmers dislike, and it can also reduce chemical spend, damage risk to pool surfaces, and wear on equipment. For homeowners searching “low chlorine pool” or “alternative to saltwater chlorinator,” the appeal is healthier-feeling water plus simpler weekly upkeep. https://low-chlo.com/ The Low-Chlo sanitizer system is described as a mineral-based pool sanitizing system that is not “new science,” but a technology adapted from established wat...

Think All Pool Acids Are the Same? Think Again

Image
Muriatic acid is one of the most common tools for lowering pool pH, but most problems start with misunderstanding what “strength” really means. Pool acid is often discussed in terms of Baumé, which relates to density and helps indicate the percent concentration of hydrochloric acid. Because muriatic acid is heavier than water, it sinks when poured, which is why dosing technique matters for surface protection. A key takeaway for pool chemistry is that the industry-standard 31.45% muriatic acid behaves very differently than big-box store products that can be closer to the mid-teens in concentration. If you use a weaker acid and follow a calculator built for 31.45%, you may underdose, see little pH movement, and assume something is “wrong” with the water.   Accurate dosing depends on matching your calculator inputs to the actual product. Many LSI-based tools and pool dosing charts assume 31.45% muriatic acid, so switching to 15% without adjusting can cut effectiveness roughly in ...

Surprising Pool Chemical Reactions Every Pool Pro Should Know

Image
Pool chemistry problems often look like “bad luck,” but many are predictable reactions that show up the same way on routes everywhere: sudden sanitizer demand, instant cloudiness, rough plaster, and filters that plug overnight. A key example is cyanuric acid (CYA). The common belief is that stabilizer never leaves the water unless you drain and refill, so a low reading must be dilution from rain or splash-out. Dilution is real, but it is not the only explanation. Under certain conditions, bacteria can convert cyanuric acid into ammonia, and CYA can drop dramatically over winter. For pool service professionals, that matters because ammonia drives chlorine demand through the roof, turning a routine cleanup into repeated dosing with little result until the underlying demand is satisfied. Another misconception shows up when calcium hardness is low and you want a fast correction. Calcium chloride is effective, but it is an exothermic reaction that can heat water enough to burn on contact if...

The Ultimate Pool Route Start Checklist

Image
A pool service truck is more than transportation. It’s your mobile warehouse, your problem-solving kit, and the difference between finishing a route on time or losing hours to supply runs. A smart pool service startup checklist focuses on what you touch every day: core pool chemicals, reliable testing, and the small replacement parts that fail most often. Stocking liquid chlorine and muriatic acid in practical quantities keeps you ready for routine sanitizer demand and pH control, while calcium hypochlorite offers flexible shock power in a form you can transport or even leave with a customer when needed. Trichlor tablets belong with the customer, but keeping a bucket on the truck prevents emergencies when tablets run out unexpectedly. Adding diatomaceous earth supports proper DE filter backwash and recharge, which improves filtration and water clarity compared with “quick backwash” shortcuts.   A well-planned chemical lineup also includes purpose-built cleaners and lubricants ...

Surviving Extreme Heat on the Pool Route

Image
Running a pool service route during a summer heat wave is more than discomfort, it is a real safety and performance problem. When temperatures push past 100 degrees, your body struggles to regulate core temperature, and that affects focus, mood, and decision-making. For pool technicians, that can show up as slower stops, skipped steps, and higher risk of heat exhaustion or heat stroke. Smart pool maintenance in extreme heat starts with the basics: hydration, getting out of direct sun whenever possible, and accepting that fatigue is a normal physical response, not a motivation issue. If you plan for the heat instead of fighting it, you protect your health and keep service quality steady for customers.   The biggest “hidden” heat strategy is preventing the messy work that explodes in summer: algae. Brushing algae in full sun wastes time and energy and turns a normal weekly stop into a grind. The foundation is proactive filter cleaning before peak season, ideally in March or Apri...
