Tornado Fish Pond Algae Block

Reduces Algae in Fish Ponds

Tornado Fish Pond Algae Blocks are a very simple, effective solution for algae in small fish ponds. Each block treats 800L of pond water and dissolves over time (can also be broken up into 4 pieces which each treat 200L for smaller ponds). Best used preventative or after manually removing most of the algae if it is a heavy infestation.

  • Suitable for ponds with fish or aquatic plants
  • Treats 800L per block or can be broken on to 4 parts which treat 200L each
  • Tornado Feature Pond Algae Block available for ponds without fish - Click Here
  • Blocks dissolve over 1-2 weeks depending on conditions and circulation
  • Do not use in ponds without a pond pump running
  • Repeat if algae re-appears
  • Do not overdose or use another block until previous block has fully dissolved

Aussie's Observations about Tornado Fish Pond Algae Block

Budget • Good • Better • Best • Superior

Suitable for:

Small ponds and water features with plants or fish.

What we liked:

Very easy to use. 1/4 of a block treats 200l of water, just throw it in your pond.

Less than ideal:

Only for small ponds, not as precise or effective as a liquid or granular solution such as Green Away or Blanket Weed Algaway
