Description
Sirona Replenish: One-Step Hot Tub Shock and Oxidizer
Sirona Replenish is a quick-dissolving spa shock oxidizer that combines chlorine and MPS to shock, oxidize, buffer and clarify hot tub water. It is intended for mineral purification systems and is also compatible with chlorine and bromine systems. One treatment helps address contaminants and restore clear, clean spa water.
The 2 lb bottle suits regular after-soak and weekly maintenance. At 1–1½ oz per 300 gallons, it provides about 21–32 doses for a 300-gallon spa (32 oz ÷ 1½ oz, or 32 oz ÷ 1 oz); follow the directions on your container.
Sirona Replenish Spa Shock Combines Chlorine and MPS
Replenish pairs chlorine with MPS in a one-step spa shock oxidizer. It is formulated to shock and oxidize spa water while helping buffer and clarify it.
Hot Tub Shock Dose and Maintenance Frequency
For normal bathing loads, add 1–1½ oz per 300 gallons after each use and once a week for maintenance. More frequent or heavier doses may be needed during periods of very heavy use; follow the directions on your container.
Quick-Dissolving Spa Shock, No Premixing
Replenish dissolves quickly and does not need to be premixed. With the pump and filter running, broadcast the dose evenly over the spa water while the spa is not in use.
Compatible With Mineral, Chlorine and Bromine Systems
Replenish is ideal for mineral purification systems and is also compatible with chlorine and bromine systems. In bromine systems, it oxidizes inert bromide to help regenerate active bromine.
