Tetra Pond Block 4-Count – Algae Control for Ornamental Ponds (Treats 250 gal/block)

Keep Pond Water Clear with Tetra Pond Block 4 Count

For five decades, Tetra has blended reliability with simplicity for pond enthusiasts. The Tetra Pond Block 4 Count is designed to help manage algae growth in ornamental ponds and fountains, supporting clearer water and a more enjoyable viewing experience. This four-block pack is straightforward to use and aligns with a regular maintenance routine. Each block typically dissolves over about 30 days, releasing its active ingredients gradually to help maintain your pond’s balance. It is intended for containerized ponds and fountains only and should not be used where live plants are present.

How it works

The blocks release active ingredients as they dissolve, enabling coverage across a broad area of the water. Use one block for water volumes between 100 and 250 gallons. When the previous block has fully dissolved, replace it to sustain ongoing maintenance. Dissolution usually takes around 30 days, though factors like water temperature and flow can influence timing.
