Acid Magic Muriatic Acid 1 Gal - Low-Fume pH & Alkalinity Reducer | USA-128-1

Acid Magic (USA-128-1) is a 1-gallon low-fume muriatic acid that makes lowering pool pH and total alkalinity far less unpleasant. It is a buffered, full-strength replacement for standard muriatic acid — same acid power, but with up to 90% fewer fumes and none of the skin burns you get from ordinary muriatic. It also works for acid-washing and cleaning surfaces. For anyone who dreads handling regular muriatic acid, this is the easy, safer alternative that does the same job.

Highlights

• Buffered Muriatic Acid: Full-strength, 1-to-1 replacement for standard muriatic acid.
• Up to 90% Fewer Fumes: Much less harsh to breathe than ordinary muriatic acid.
• Gentler to Handle: Does not burn skin on contact the way standard muriatic acid does (still wear gloves and eye protection).
• Lowers pH & Alkalinity: Reduces high pH and total alkalinity, and cleans or etches surfaces.
• NSF/ANSI 60 Certified: Certified for drinking-water treatment use.

How to Use It

• Test first: Check pH and total alkalinity and run an acid demand test to find the right dose. As a rough guide, about 1 quart per 10,000 gallons lowers total alkalinity around 10 ppm.
• Add safely: With the pump running, pour Acid Magic slowly into the deep end near a return jet. Keep it away from walls, liners, and metal fittings.
• Circulate and retest: Let it mix, then retest before adding more. Avoid overcorrecting.
• Handle with care: Always wear chemical-resistant gloves and eye protection, and never add water to acid.

Frequently Asked Questions

What is it for?
Lowering high pH and total alkalinity in pools and spas, and acid-washing or cleaning surfaces.

How is it different from regular muriatic acid?
Same acid strength, but buffered so it produces about 90% fewer fumes and is gentler on skin.

How much do I add?
Run an acid demand test; roughly 1 quart per 10,000 gallons lowers total alkalinity about 10 ppm. Add gradually and retest.

Do I still need gloves?
Yes. It is still an acid — always wear gloves and eye protection.
