Costs to keep your pool clean keep rising, with no relief in sight

- Ron Hurtibise

As hot summer temperatur­es approach, the price of relief — plunging into that cool, blue swimming pool in your backyard — continues to increase.

Pool owners who depend on trichlor tablets, one of the most convenient ways to kill algae, mold, bacteria and other unwelcome intruders, are feeling it hardest. On Amazon, a 50-pound bucket of In The Swim-brand 3inch tablets that sold for $110 back in 2020 shot up to $170 in April 2021 and is now listed at $250.

Prices are comparable at South Florida retail stores, including Lowes and Home Depot.

Touch Pool Services says he expects prices of a 50-pound bucket of the three-inch tablets to hit $350 by the end of summer. One reason for the continuing increase, he says, is that some pool service companies bought as many tablets as they could to avoid running out.

At Allbrite Pool Supplies in Coral Springs, prices have climbed so high, “I don’t even have any in stock at the moment,” owner Tracey Eagan says. “They’re hard to find and I’m opting not to buy them.”

Costs of all dry pool chemicals, including granulated shock used to quickly kill contaminan­ts, have increased, she says.

Eagan traces the tablet shortage back to the 2020 destructio­n by fire of a Louisiana plant that made 40% of the nation’s chlorine tablets. That plant is expected to open later this year, barring disruption­s from labor or materials shortages, and should help bring tablet prices down by 2023, according to a report on the home improvemen­t services website Angi.com.

Making matters worse, a huge fire in January destroyed another chlorine tablet plant, along with 100,000 chlorine tablets, in New Jersey.

Many pool owners prefer tablets because, along with their 90% chlorine concentrat­ion, they contain cyanuric acid, which helps stabilize the chlorine and make it last longer. They can be easily dropped into a floating dispenser or automatic chlorinato­r and left alone.

But as tablet prices rise, many pool owners are turning to the more readily available liquid chlorine, Eagan says. Liquid chlorine prices have increased but at a lower rate. A 2.5 gallon bucket at her store currently sells for $7.01 plus tax, but Eagan says suppliers are warning of a 15% price hike in May.

Using liquid chlorine is more labor-intensive than tablets, Silva says, because owners may also need to add cyanuric acid, to prevent the sun’s UV rays from degrading the chlorine, as well as sodium bicarbonat­e (baking soda) to raise alkalinity, and calcium chloride to prevent corrosion and scaling.

Phosphate remover, not included in tablets, might also be necessary to prevent algae growth whether using liquid chlorine or tablets, Silva says.

Rising pool chemical prices has forced Silva to raise his monthly service prices significan­tly over the past two years, from $85 to $125, he says. Nearly 75 customers, just under 10% of his client base, have discontinu­ed their service as a result.

Eagan says some of her customers have opted to install salt-based sanitizati­on systems. While the initial investment is steep — between $1,200 and $2,000 — the salt regenerate­s within the pool and does not dissolve like chlorine. Pool owners typically only add about three to five $13 bags of salt during the summer, when heavy rains dilute the concentrat­ion.

Silva says inflation is hitting the labor side of the pool maintenanc­e industry as well.
