FarmerTy Posted January 12, 2015 Share Posted January 12, 2015 I'd look into it a bit more but I don't think Hanna makes a Magnesium checker. The calcium checker has issues with accuracy. I like the alk checker and the phosphorus checker. Link to comment Share on other sites More sharing options...
victoly Posted January 12, 2015 Share Posted January 12, 2015 Mg checker does not exist. Any analytes with titrations have to have a modified method to work with a photometer. The titration for alkalinity is really simple, and hanna used an alternative method to make it work with their HC checkers. Mg and calcium are both multistep titrations that don't really work well IMO for photometry. Case-in-point is their calcium checker. Link to comment Share on other sites More sharing options...
Nutz4Fish Posted January 13, 2015 Author Share Posted January 13, 2015 Thanks for the info on the Calcium checker. I do not know why I typed Magnesium. I meant Phosphourus checker. Link to comment Share on other sites More sharing options...
Manny Posted January 13, 2015 Share Posted January 13, 2015 I do have a Ca checker I could sell you if you wanted to give it a go. But like the others say, I'm not a big fan of it. Link to comment Share on other sites More sharing options...

Is it even close? Why is everyone so against it. Just wondering I bought ALK and Phospate and I really like te ease of use. Are you located in Bryan I dont see how we can meet unless you come this way Link to comment Share on other sites More sharing options...

You can Google it pretty easy to read more on the subject if wanted but that sums it up pretty nicely. Link to comment Share on other sites More sharing options...
Reburn Posted January 16, 2015 Share Posted January 16, 2015 To answer the question simply. It's neither accurate to the true ppm in the tank and it's not consistent. You can perform the test 3 times and get 3 very different readings. You can't dose or adjust dosing when you have no faith that your testing equipment is giving you consistent results.
