This would be a good opportunity for some of you to upgrade your test kits from the "low, medium, high" kits that always pop up in the water chemistry Q&A threads. Also, a good opportunity for those of you that don't have a complete set of kits. How many times have we seen a thread that starts off with my calcium is high, but never mentions where their alkalinity is because they don't have a kit? Or how many times have you seen a post by me asking what their magnesium level is when a tank is out of balance?

I test my calcium weekly and the Seachem kit gives me almost 3 years worth of tests (150 tests) for a little more then I pay for the Salifert Kit. Ordinarily a kit that old might be a problem but since it comes with a calibration standard, its not in this case. One othter advantage of the kit is that it comes in the little plastic lunch box type container. I have found these to be very useful for storing spare parts and spare test kit stuff. One of them is in the process of becoming my "coral frag kit."
