Maintaining the right pH level in your swimming pool is essential for water clarity, swimmer comfort, and the longevity of your equipment. While liquid acid (typically muriatic acid) has been the go-to solution for decades, carbon dioxide (CO2) is becoming a preferred alternative for many pool owners and professionals. At Poolsmith Technologies, we support smart, sustainable solutions that protect your investment and your health. Here are five key reasons why using swimming pool CO2 systems instead of liquid acid makes sense for your pool.
1. Improved Safety for Homeowners and Pool Technicians
Liquid acid is a highly corrosive and dangerous chemical. Improper handling can lead to burns, inhalation injuries, and property damage. Even a small spill can be harmful to both people and pets. CO2, on the other hand, is a much safer alternative. It eliminates the risk of chemical burns and toxic fumes, offering a cleaner and safer environment for anyone maintaining the pool.
2. Gentle pH Control Without Harsh Chemicals
CO2 lowers pH by forming carbonic acid when dissolved in water—a much milder substance than muriatic acid, which typically has a pH between 1 and 2, according to How Stuff Works. The gentler approach offered by CO2 reduces the chance of damaging surfaces, seals, and sensitive equipment like heaters or pumps. Swimming pool CO2 systems allow for more consistent and controlled pH adjustments, leading to less chemical fluctuation and better overall water chemistry balance.
3. Reduced Wear on Pool Equipment
Harsh acids can slowly degrade pool components, especially metal fixtures, filters, and salt cells. Over time, repeated exposure to liquid acid can shorten the lifespan of your pool system. CO2 avoids these corrosive effects, helping extend the life of your plumbing, automation systems, and other pool hardware. This means fewer repairs and replacements down the line, thus saving you money in the long term.
4. Environmentally-Friendly Pool Management
Using CO2 is a more eco-conscious choice. Because there are no hazardous liquids to store, handle, or transport, CO2 reduces the risk of environmental contamination. It also lessens the demand for harsh chemical production and transportation. Choosing swimming pool CO2 systems aligns with Poolsmith’s commitment to sustainable pool care and supports a greener future for your home and community.
5. Greater Convenience and Automation
CO2 systems can be easily integrated with automated controllers, allowing for precise and hands-free pH management. This means fewer manual adjustments, less guesswork, and fewer trips to the store for acid refills. Once installed, CO2 delivery is consistent and reliable, making pool ownership more convenient and giving you more time to enjoy your water instead of maintaining it.
Switching from liquid acid to CO2 isn’t just about chemistry—it’s about creating a safer, more efficient, and more sustainable pool environment.
