Alright, this morning I tested the Shrimp Mineral GH/KH+ on an unopened gallon of distilled water to see what kind of results I got.
First, I shook the Salty Shrimp Minerals to insure the powder was well mixed. Then I tested the distilled water still in the jug. It had a pH of 5.4 and a TDS of 0. (I calibrated both pens prior to starting the test.) I added the Salty Shrimp Minerals to a TDS of 216. Then tested pH (7.92), API GH test was 9, and API KH test was 3.
My conclusion is that the Salty Shrimp Minerals is a bad batch. I have more arriving tomorrow so I can test it then. The reason I hesitate to not use it is my shrimp were purchased from "USA's Largest Online Retailer of Freshwater Shrimp", according to him anyway and he says that this is the only thing he uses and recommends. Maybe I need to take the advice of Ayn Rand from her novel "Atlas Shrugged" ... when all else fails, check your premise.
Any suggestions or ideas anyone has are welcome.
