After using Kent for years, thought this new product was worth a try. Huge mistake!! Crashed my stony tank. There numbers are not what they say they are. Did a 25 gallon test & came back lower than what they say.
I would not recommend this product to anyone. Plus there tech support is trying to blame my refractometer being off, but had it tested & it is right on. Also there tech support lacks in trying to make things right with me!!
Do not buy!!!
