Gone to a good home
Its frustrating when test kits give false readings. My Salifert Mg test kit (new box purchased a year ago. Not expired) was giving bad readings. Basically it does not change from pink to blue even when the whole syringe of reagents is used. Giving the perception that Mg is > 1500ppm..
The reality was Mg was dropping steadily to 1260ppm range for an extended period of time but it was not detected. Not good. I think this is a very isolated case. Possibly poor storage conditions or sitting standstill for too long? This post is not to bash a particular brand of test kit. Key point is if you suspect a faulty test kit, take action ASAP. Borrow or get another kit and not be complacent.
I then got a Nyos magnesium test kit instead and find it very good. The color change from pink to blue is very distinct.
Gentle reminder to reefers to wash & dry their frag cutter. Over time, rust can form even on 316 stainless steel.
