This episode of The Pool Guy Podcast Show dives deep into the critical differences between types of pool acids, emphasizing that not all acids are equal—especially when it comes to strength, effectiveness, and safety. Hosted by a 35-year veteran in the pool industry, the episode breaks down muriatic acid (31.45% HCl), dry acid (sodium bisulfate), and Acid Magic, highlighting how weaker acids like those sold at Home Depot (around 15.7%) require double the dose to achieve the same pH reduction as industrial-grade muriatic acid. The host explains how alkalinity levels dramatically affect acid efficiency, with higher alkalinity buffering pH changes and requiring significantly more acid. He shares practical tips like using the PoolCalculator.com app to adjust for acid strength, the importance of wearing nitrile gloves and safety goggles, and the dangers of acid spills on decks—especially stamped concrete. The episode also covers handling techniques, such as the 'dip method' to prevent drips, and compares cost, safety, and ease of use across products, concluding that while alternatives like Acid Magic offer lower fumes and safer handling, they come at a steep price premium. The host advocates for muriatic acid as the most effective and economical choice for professionals, despite its hazards.
Muriatic acid strength varies significantly—Home Depot's 15.7% acid requires double the dose of 31.45% industrial-grade acid.
Alkalinity levels directly impact how much acid is needed; high alkalinity (180 ppm) can require nearly double the acid compared to low alkalinity (60 ppm).
Always dilute muriatic acid in water before adding to the pool to prevent surface etching and splashing.
Use the dip method or pour acid into a bucket with water first to avoid deck damage and reduce splash risk.
Acid Magic is safer and produces 90% less fumes but costs twice as much, making it less practical for pros.

The Truth About Muriatic Acid Strength
“If you're using the Home Depot 15% acid, you're going to have to basically double the dose that you're getting out of the calculators that you're using.”
How Alkalinity Affects Acid Efficiency
“When I add the acid to the pool, it's going to, yes, lower it to 7.4. But since there's so much alkalinity in that pool buffering it, chances are it's going to bounce right back up to 8.0 within a matter of a day or even sooner.”
Dry Acid (Sodium Bisulfate) – Pros and Cons
Dry acid is safer to handle and doesn’t produce fumes, but it’s highly affected by alkalinity, requires dissolution in water, and is more expensive than liquid acid.
Safety, Handling, and Spill Prevention
“I still have the scar from that. It was a pretty big splash, by the way, and thankfully it didn't hit my face.”
