In order to keep our testing methods as precise as possible, beginning September 16 we will be running routine maintenance on our lab equipment. The time frame for this maintenance will be between seven and ten business days, during which we will not be performing water testing. This will not affect our website and we will still be taking orders. We highly recommend sending samples NO LATER than Sept 10 to help ensure they reach our facility to be tested by Sept 15. We expect to resume water testing Mon, Sept 26, and we thank you for your patience during this time.

Wonderful analysis, corresponded with what I believed was happening. I could never get some of the [home] tests right and the results I was getting didn”t correspond with what was going on in the tank. Thanks for the great service, I recommend you to all of my reefers.
