Extended-Formula Fountain Treatment, 64 oz
Prevent for Fountains XT uses an extended-release formula to control algae and mineral scale deposits in decorative water features. The 64 oz (1.89 L) size is the mid-volume option, offering more treatments per bottle than the 32 oz while staying manageable for most patio and courtyard fountains.
What It Does
The XT formula releases active ingredients over a longer window than the standard SL, giving the treatment more staying power between applications. It targets the single-celled algae that cloud water and form green films on basin walls and spitter faces, and inhibits the calcium and mineral deposits that concentrate wherever water evaporates on fountain surfaces. Consistent use keeps fountains running with less hands-on maintenance time.

How to Use
Shake the bottle before each use. Add the dose to the fountain basin with the pump running to circulate the treatment evenly. Apply weekly during warmer months. The XT formula's extended action is most effective when applied consistently before algae establishes, not after. Not for use in ponds with fish or aquatic plants.
Ideal for mid-size decorative fountains used seasonally on Canadian patios and gardens, where algae control is needed from spring startup through fall shutdown.
