Koi Medic Salt Test Pen

Trans Instruments has specially designed the KoiMedic tester to measure the delicate salt concentration in the pond. Two models of your choice measuring 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.

The Koi Medic provides accurate results and is very easy to use, simply turn on and hold in the pond. Within a couple seconds the LCD displays the salt concentration measured in percentage. 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 has been used to control string algae. Nevertheless, 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.
