I have the ULR Phosphorus meter and find it very accurate. I did some experimenting around on it's accuracy. I diluted the water I was testing with P-free seawater and found it gave bang on results.
One thing about the alk-meter I just read is that they had reliability issues with the powder reagents and are replacing them with liquid: http://reefbuilders.com/2011/01/24/h...placed-liquid/ For alk, Ca and Mg, the ordinary test kits (i.e. Salifert) are accurate enough for my needs.
