Application Rate

Apply pHusion up to every 3 days at the prescribed rate until pH levels come into the safe range (6.5-8.0).

For Best Results

pH is typically lowest at dawn and highest at dusk so it is important to test pH at the same time of day. Once pH has been brought to a safe level, use pHGuard to stabilize your pond preventing future pH swings.
