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.

Salinity Meter Shipped to Hawaii

I was looking for this meter on many different websites because I couldn't get it from my local Koi Farm, and when I couldn't get it shipped to Hawaii I contacted them and immediately got a response with a solution, it shipped out the next day and I got it quicker than I could have imagined! Great customer service! Such a great company!

Our local koi pond care expert recommended the salt meter. In searching for the specific recommended meter, I found your website and ordered the same. The service, ease of web ordering and incredibly fast shipping greatly impressed us with your company. Thank you!!!

Great service, great product

Hi Ben, I sent in a response right after I got the meter, but evidently it didn’t get to you. The salinity meter works great, and I can’t believe that you were able to send it from Washington state to Virginia in 2 days with free shipping as well. I couldn’t ask for more. I bookmarked your sight if that tells you anything. Thanks so much. Terry
