OASE Lake Therapy OptiLake pH Stabilizer 50 lb

OASE Lake Therapy OptiLake is a pH stabilizer and carbonate hardness buffer designed for lakes and ponds used for fisheries, recreation, and aquaculture. It rapidly regulates pH to the target range of 7.5-8.3 — the optimal range for plant life, fish, and herbicide/treatment efficacy. As a simple alternative to traditional liming, one annual OptiLake treatment improves biology and promotes the biodiversity of the aquatic organisms that contribute to a healthy lake environment.

What It Treats

• pH instability — both acidic and highly alkaline swings
• Low carbonate hardness / low alkalinity
• Toxic ammonia and nitrite formation (worsens at low pH)
• Reduced efficacy of herbicides and other water treatments
• Lakes needing a simpler alternative to lime

How To Apply

• Dry broadcast application — scatter evenly across the water surface
• Important: DO NOT mix with water before application
• Annual application sustains ideal conditions for an entire season

Treatment Rate (per acre-foot, annually)

Key Features

• Buffers pH and carbonate hardness to the 7.5-8.3 target for healthy fisheries
• Simpler alternative to liming — broadcast application, no water source mixing required
• Improves fishery productivity — creates conditions for plant and fish growth in trophy ponds
• Supports herbicide and treatment efficacy — many pond treatments work best in a stable alkaline range
• Commercial-grade — used by lake managers for annual pH maintenance of recreational lakes and fisheries

✅ Safe for fish, wildlife, and aquatic plants.
