USER INSTRUCTIONS FOR T-FLOW TRONIC
WHAT YOU NEED TO KNOW ABOUT ALGAE
A pond is a closed eco-system in which plants and fish live together. Algae are
vegetable organisms that need sunlight (photosynthesis) as well as nutrients (carbon
dioxide, nitrogen, and phosphates) to grow and produce oxygen. Pond fish need this
oxygen to live. A pond is a relatively small area in which the balance between these
processes can be easily disturbed. When you remove algae, you take away an impor-
!
tant source of oxygen too. Extra aeration of the water may then be necessary to
ensure a sufficient oxygen supply for the fish. Nutrients may accumulate and can
cause harm to the fish. To avoid this, we recommend that you add nutrient absorbing
materials such as zeolite to your pond filter or that you partially refresh the water.
WHAT YOU NEED TO KNOW ABOUT THE T-FLOW TRONIC
With this T-Flow Tronic Velda brings a revolutionary system to the market that eli-
minates fibrous and slime algae from your garden pond in a way that is safe for fish
and plants. The core of the T-Flow consists of an anode (1), made from a mineral
copper alloy developed by Velda, and a stainless steel cathode (2). By means of the
microprocessor controlled display unit (5), pulses are generated, which are led to the
core of the T-Flow. Through these pulses, positively charged copper ions are released,
also known as mineralization. In a defined concentration, these ions form a natural
barrier against algae. Velda brings 4 different models of the T-Flow Tronic to the
market. The function of the models is identical. The difference lies in the capacity to
bring the copper ions to the active concentration of circa 0.3 ppm for any pond size.

WHAT YOU NEED TO KNOW ABOUT THE WATER QUALITY AND THE T-FLOW
l If sodium has been added to the pond water (for example kitchen salt or sea
salt) the water should be completely refreshed before using the T-Flow Tronic.
l Avoid using water treatment products and the T-Flow simultaneously. If it is ne-
cessary to use these treatments, the T-Flow must be turned off during this period.
l Measure the values of the pond water and adjust them if necessary. Make sure
the water is hard enough, with a minimum carbonate hardness (KH) of 6 °GH
and a minimum general hardness (GH) of 8 °GH. The pH-value should be at least
pH 7 before using the T-Flow Tronic.
