The KoiMedic Digital Salt Test Meter is specifically designed to measure and monitor the salinity levels for your Koi pond. The meter is very accurate and easy to use, simply turn it on and dip into the pond. Within two seconds, the LCD will display the salt concentration measured in "percentage". Koi Medic meter measures salt content which helps control algae growth, detoxifies Nitrite, and aids in eliminating parasites and the overall health of koi fish.

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.

Needless to say, being able to precisely measure and control your salinity is an absolutely must for any Koi owner.

Excellent Service and Product

It was difficult to find a salt meter for pond fish (rather than tanked salt water fish). I am glad to have found one from a reputable source. It works well and serves my needs.

quick, accurate, life saver

I used to guess at what my salinity was until I wiped out my entire pond b/c my salt level was so high. I will not make that mistake again. The Koi Medic salinity pen has been a great addition to my pond keeper collection of gizmos. It's easy to read, light weight, comes in a nice storing case, and most importantly is fast and accurate. I'd highly recommend for anyone who is adding salt to their ponds to make the investment in this. I wish I had from the beginning and would've saved myself a lot of $$ and heartache. lesson learned.

My fish thank you

Worked perfectly out of the box. I can now add salt to my pond without trying to guess if I added too much or too little. Fast shipping. Good service. I'll be back!
