How to Know When a Pool Filter Is Done

Image
Pool filter upgrades usually come down to one decision: does the system just need fresh filter media, or is the entire filter tank near the end of its life. “Filter media” is simply what does the actual trapping inside the filter, and it changes by type: cartridge filters use cartridges, DE filters use grids coated with DE powder, and sand filters use sand (sometimes glass media). Each option has a different lifespan, maintenance style, and failure mode, so smarter troubleshooting starts with matching your symptoms to the media. If your pool struggles to stay clear despite solid water chemistry, or you see steady pressure rise and poor circulation, that often points to filtration capacity, clogged media, or worn parts rather than a sanitizer problem. Sand filters are the trickiest to diagnose because the sand can seem “fine” for years, yet filtration can slowly degrade. Some owners never change sand, while others plan a five to eight year interval. A practical trigger is performance: i...

Before You Start a Pool Service Business, Listen to This

Image
Starting a pool service business sounds simple until you hear the warnings: most small businesses fail, there’s no safety net, and the pool industry has hidden hurdles. The truth is that “failure rates” often reflect bad execution, not bad markets. When an owner skips customer service, underestimates costs, or runs without a plan, the business bleeds out fast, just like any poorly run local shop. But a pool route in a solid area has durable demand, recurring monthly revenue, and clear ways to stand out through reliability. If you treat pool service like a real business with pricing discipline, scheduling, and communication, the odds shift strongly in your favor. A big fear is job security, especially with AI and automation. The episode makes a practical case: many office roles can be replaced quickly because software scales cheaply, while hands-on service work is harder to automate. Pools still need testing, chemical handling, equipment checks, and on-site problem solving. That doesn’t...

Residential vs. Commercial Pools: No Contest

Image
Residential pool service and commercial pool maintenance may look similar from the road, but they operate under totally different rules. A commercial pool is any pool used by a broader community like apartments, HOAs, hotels, the YMCA, or city facilities, and that definition instantly brings the county health department into the picture. Residential pool care usually happens behind a single-family home and is far less regulated, which means fewer third parties, fewer mandatory procedures, and fewer surprise shutdowns. For many pool pros, that lighter compliance load is the first big reason a residential pool service route feels easier to run and easier to scale without adding administrative drag.   Regulation changes everything in a pool care business. Commercial accounts can require CPO certification or county-specific credentials, along with strict safety codes and documentation. Health department inspection pressure adds a constant “must be perfect today” factor, because a ...

EPA vs. Sodium Bromide: The Real Story Part 2 of 2

Image
The sodium bromide debate in the pool industry often gets reduced to a scary word: bromate. But the real conversation is about exposure, how regulators model risk, and what happens when guidance is built on limited field data. Pool service professionals have used sodium bromide based algaecide products for decades, especially for stubborn yellow algae, and many were blindsided by the EPA-driven label language that says “not for use in outdoor pools.” That label shift sparked fear at distributors and on service trucks, even though the product remains legal to purchase. The bigger issue is how pool chemistry, real-world dosing, and actual human exposure differ from worst-case assumptions. A key scientific point raised is that bromate does not automatically equal harm at any detectable level, especially when exposure is tiny. The discussion leans on research suggesting the stomach’s hydrochloric acid can rapidly reduce a large share of trace bromate back into bromide, which is far less co...

EPA vs. Sodium Bromide: The Real Story Part 1 of 2

Image
The EPA interim decision on sodium bromide has sent a shock through the pool industry because it forces a label change that effectively removes outdoor pool use from products many pool service professionals relied on for fast algae knockdowns. If a sodium bromide-based algaecide now reads “not for use in outdoor pools,” distributors and retailers often stop stocking it entirely, even if the product chemistry did not suddenly change overnight. That’s why names like Yellow Treat and No More Problems keep coming up: they became shorthand for a simple, dependable algae treatment process that many technicians considered “bulletproof,” especially when paired with a strong liquid chlorine dose. A big piece of the controversy is bromate formation. Bromate is considered a probable human carcinogen, and the EPA’s interim approach assumes a worst-case scenario of 100% conversion from bromide to bromate in outdoor pools. Scott Hamilton explains that this is not chemically realistic, but it is cons...

Nautis VSF Maintains Perfect Flow Automatically!

Image
Variable speed pool pumps promise energy savings, but most owners and even seasoned pool service pros still end up guessing at RPM settings. That guesswork shows up later as cloudy water, weak heater performance, noisy plumbing, or a filter that slowly clogs until circulation quietly drops. On the Pool Guy Podcast Show, Sean McDermott from H2 Flow Controls introduces the Nautilus VSF pump, built around a simple idea: speed is just a tool, but flow is the outcome that actually runs a pool. By monitoring real flow instead of relying on a theoretical pump curve, the pump targets consistent circulation that supports both water quality and efficiency.   The standout feature is adaptive flow, which lets you enter pool volume and choose a constant flow mode or a turnover mode. Instead of “set it to 2,200 RPM and hope,” the pump adjusts itself to maintain the required gallons per minute as conditions change. Filters load up gradually, in-floor cleaning systems cycle, water features op...

Coming Soon! The New PCTI Video Training Program

Image
Residential pool care often gets treated like the “informal” side of the industry, even though most pool service pros spend their days in backyards, not at commercial facilities. That gap shows up in training: commercial operators can earn the CPO certification, but residential technicians frequently learn chemistry through trial, error, and scattered advice. In this podcast conversation, we dig into why that is a problem and why Bob Lowry’s approach to pool chemistry training became so influential. His material was built for the backyard professional, with clear explanations and poolside decisions you can actually apply on route, not just theory for the classroom. We also talk about how the Pool Chemistry Training Institute (PCTI) evolved after Bob Lowry and Greg Garrett passed away, and how HASA stepped in to keep the education alive. A key part of the story is access: the original training was a longer paid course, but the goal now is broad availability for residential pool service....
