Koi Medic Salt Tester

Trans Instruments has specially designed the Koi Medic tester to measure salt concentration in your pond. Choose measurements in percentage(%) or parts-per-thousand (ppt). The testers are accurate and easy to use. All you need to do is turn it on and dip into the pond water. Within a few seconds the LCD displays the salt concentration. Measures accurately from .01% to 1%.

Salt concentrations between 0.3% and 0.5%(3 to 5ppt) will upset the osmotic balance of some parasites i.e. the parasites cells will dehydrate. Salt concentration of 0.3% are effective at detoxifying nitrite and concentration of 0.25% or higher can be useful in controlling string algae.

NOTE: Salt can cause pond plant damage as the concentration increases. Floating plants (water hyacinth, water lettuce, etc.) are affected at lower concentrations than most bog plants and water lilies.
