The Velda T-Flow Tronic blanketweed remover is a revolutionary system that eliminates fibrous and slime algae from your garden pond in a way that is safe for fish and plants. The core of the T-Flow Tronic blankweed remover consists of an anode, made from a mineral copper alloy developed by Velda, and a stainless steel cathode. By means of the microprocessor controlled display unit, pulses are generated, which are led to the core of the T-Flow Tronic. Through these pulses, positively charged copper ions are released, also known as mineralization. These ions are also referred to as minerals. In a defined concentration, the ions form a natural barrier against algae. The concentration of copper ions to remove fibrous algae and stop the growth lies between 0.2 en 0.3 PPM. This is an absolutely safe concentration for people, animals, and plants. For comparison, according to the European drinking water standards, 2 PPM is the maximum allowed for drinking water. A positive side-effect of using the T-Flow Tronic is that the pond water will be healthy, and it spreads a neutral, fresh scent.

At last a blanketweed remover which is cheep to run, safe and highly effective.

What is Effective Volume ?
The effective volume is the quantity of water in your pond, plus an allowance for shallow and or ponds exposed to high levels of sunlight. Both of these situations will result in a higher than normal algae growth, and fish pollution. We advise that to ensure your that your equipment is correctly sized, the effective volume be considered the minimum size for the equipment you select. However do remember to check the details of the product you are interested in, to ensure that there are no other allowances or consideration specific to that product are required.
