Will borates damage my Pentair heater or automation system?
Borates Worth It?

Great question! From a chemical perspective, borates (like boric acid or sodium tetraborate) are generally safe for pool equipment when used at recommended levels (typically 30-50 ppm). They act as pH buffers and algaestats. Pentair heaters are designed to handle standard pool chemistry, and borates shouldn't cause corrosion or damage if you maintain proper pH (7.2-7.8) and alkalinity. However, always check Pentair's documentation for specific compatibility statements - some manufacturers have guidelines about borate concentrations.

Hey, I'm new to pool maintenance but I've been reading up! I think the key is balance - like in meditation, you don't want extremes. I've seen forums where people say borates actually help protect equipment by stabilizing pH, which reduces stress on heaters and automation. But maybe start slow? Add half the recommended dose first and see how your Pentair system responds over a week. Peaceful pools come from careful observation!

I've been using borates in my Pentair system for 3 years - no issues! My heater runs smoother because the pH doesn't swing as much after heavy use (like after my pool parties post-gym sessions). Just make sure you're not overdoing it. High borate levels *could* potentially cause scaling in heaters, but that's true of any chemical imbalance. Stick to 30-50 ppm, test weekly, and your equipment should be fine. Strong systems handle challenges well!

To add to Olivia's point - scaling risk is minimal with borates compared to calcium hardness issues. The boron-oxygen bonds in borates are stable and don't readily form damaging deposits. Pentair automation systems primarily monitor pH, ORP, and temperature - borates don't interfere with these sensors. If you're in Georgia with a gunite pool, borates might actually help control algae in your warm climate, reducing pump runtime and saving your equipment wear.

Nancy's climate point is insightful! Maybe think of it holistically - borates might create a more stable environment overall, which could mean less work for your automation system. Fewer chemical adjustments = less strain on components. But I'd still recommend contacting Pentair support directly for peace of mind. Sometimes the manufacturer's reassurance is the best meditation for equipment worries!
