20,000LPH Velda T-Flow Anti-Algae Pond Filter

T-Flow Tronic is a revolutionary system which removes fibrous and slimy algae from your garden pond permanently. Owing to the sophisticated water flow its operation is quite effective and extremely easy to dose.

The core of the T-Flow Tronic consists of an anode, made from a mineral copper alloy developed by Velda and a cathode made from stainless steel. With the help of a microprocessor pulses are generated, which are guided to the core of the T-Flow Tronic. This causes positively charged copper ions to be released.

These copper ions control algae in a natural way already at a low concentration. A copper content of 0.2 tot 0.3 ppm is sufficient to remove fibrous algae and to stop their growth.


  • This will rid your pond of suspended algae and blanket weed too, leading to a clear and healthy pond which you can enjoy
  • Using the microprocessor controlled display unit, pulses are generated which are fed to the core of the T flow. These pulses positively charge copper ions which are released. This process is known as mineralisation

Note: Needs corresponding pump to work.

  • Pond Content: 10,000 – 35,000 litres
  • Pump Capacity: 10,000 – 20,000 litres per hour
  • Recommended pump: Green Line 15000

Tips on Installation and Maintenance

A lot of water features come pre-assembled for the most part, with just a little hose/pump connecting to do before plugging it in to a solar panel or mains socket. Some of our bigger ones require wiring in a plug (which might involve a Part P Certified electrician), but otherwise all instructions will be included.

If you've got any questions, why not check out our Installation Guide for tips on installation location, power and even style tips!
