Sirona® Brom Tabs
Product Overview
A proven choice for spa owners who need consistent sanitation without the rapid dissipation seen with traditional chlorine.
Sirona® Brom Tabs provide reliable sanitation with Sirona® Brom Tabs featuring a 99.0% concentration of active hydantoins in a 2.2 lbs. container. These slow-soluble bromine tablets are what pool techs reach for when maintaining spas or small indoor pools where pH stability and a constant sanitizer residual are critical. Unlike standard chlorine, these tablets remain effective in higher temperature ranges and do not require stabilizer (CYA) to function.
Benefits & What Makes It Different
99.0% Active Hydantoins
High-purity 1-bromo-3-chloro-5,5-dimethylhydantoin ensures maximum sanitizing power per tablet for effective bacteria and algae control.
Slow-Soluble Delivery
The compressed tablet form dissolves gradually over approximately one week, preventing the chemical spikes often associated with granular applications.
Broad Compatibility
These tablets are the standard specification for systems utilizing ozone or mineral treatments, enhancing overall water clarity and sanitation.
Product Details
1-bromo-3-chloro-5,5-dimethylhydantoin, 1,3-dichloro-5,5-dimethylhydantoin, and 1,3-dichloro-5-ethyl-5-methylhydantoin (99.0%)
Maintain 3-5 ppm in spas or 2-4 ppm in pools; typically 15-20 tablets per 10,000 gallons to establish a bank, then adjust feeder flow.
Compatibility
- Compatible with ozone and mineral systems
- Do not mix with dry chlorine or other chemicals
- Safe for vinyl, fiberglass, and plaster surfaces
When To Use This
Pro Tip
In our experience, bromine is far more effective than chlorine in hot water environments like spas because it doesn't 'gas off' as quickly at temperatures above 100°F, and its byproduct, bromamines, still retains sanitizing power.
Common Questions & Instructions
How many Sirona Brom Tabs should I use for my spa or pool?
For initial treatment, add enough tablets to reach a 3-5 ppm residual; typically, 1-3 tablets per 500 gallons in a feeder will maintain levels for up to a week. For a 10,000 gallon pool, you would need approximately 20 tablets to establish a bank.
Do Sirona Brom Tabs affect the pH or alkalinity of my water?
Bromine is naturally acidic with a pH of approximately 4.5, so regular testing is required as it will gradually lower your total alkalinity and pH levels over time during routine use.
Can I use these bromine tablets in a pool that currently uses chlorine?
Yes, bromine is compatible with chlorine-based systems, but you must never mix the dry chemicals together in the same feeder or container as it can cause a dangerous chemical reaction.
