TetraPond Fountain Block 6 Count — Algae Control for Ornamental Fountains

Clear water, vibrant displays

Transform ornamental fountains and container ponds with TetraPond Fountain Block 6 Count. This slow-release solution works to limit visible algae and support a more inviting aquatic scene, even as sunlight dances on rippling water and fish shimmer below the surface.

Designed for containerized water features, the blocks help keep water looking fresh and clear while you enjoy the gentle sound of moving water and the beauty of your fish and décor. The formula targets routine algae growth in decorative waterways, offering a practical option for maintainers who value ease, consistency, and ongoing visual appeal.

What it does

• CONTROLS ALGAE: Helps prevent algae growth in ornamental water fountains and ponds.
• SLOW RELEASE: Blocks fully dissolve slowly after about 10 days.
• FOR CONTAINERIZED FOUNTAINS & PONDS: Not recommended for containers with live plants.
• EASY TO USE: One block treats between 30 and 280 gallons of water.
• CLEARS ALGAE BLOOMS: Each block dissolves to control algae and clear algae blooms.

Usage is straightforward and designed for hobbyists and newcomers alike. Start with the initial dose by matching one block to each 100 gallons (380 L) of pond or fountain water. After the blocks have fully dissolved—typically around 30 days—replace with a fresh block as needed to maintain control. In a balanced setup, you can expect clearer water and a more enjoyable viewing experience for your aquatic life and decorative features.

How to use

• Initial dose: one block per 100 gallons (380 L) of water.
• Maintenance: replace blocks after previous ones have fully dissolved, usually about 30 days.
• Volume range: one block treats 30–280 gallons of water.
• Limitations: not designed for containers with live plants.

Beyond the practical dosing, note that algae are a natural part of many water features. A balanced environment, combined with reliable, regular treatment, can help keep them in check while you enjoy the aesthetics of a clear, shimmering fountain. Since 1951, Tetra has built a broad knowledge base for fish care and pond maintenance, and Fountain Block is one of many tools crafted to support simple, effective upkeep for ornamental displays.
