Calcium Probe Type Tester

[hermit]

Does anyone out there know of a digital read-out probe tester that might exist for testing Calcium levels.. It would be soooo much easier to use that instead of having to put drop after drop of solution into a tube until it turns blue...
Just curious... Any help would be greatly appreciated...

Sounds like tour using Aquarium Systems tests. I like their tests except for their calcium test. Red Sea has a calcium test that only takes a few drops. Don't have an answer about the probe. I hear they require alot of calibrating.
