WTB Merck (D-Deltec) phosphate test kits?

[surgeonfish]

I have a bloom of algae in my tank and have become obsessed with PO4 levels. My Nutrafin kit sucked and I switched to the Salifert kit. Anyone using the Merck (D-Deltec) high precision phosphate kt? I here they are very accurate at low levels. Where can you get them?

I am using this test kit, it is from J & L. The thing is, it is an expensive test kit that you will only use a few times. Once you figure out what your phosphate levels are you will know they are either OK, or if they are high you will correct the problem. I have used it about 4 or 5 times total on my SW and FW tanks.

Since this test kit is so costly it makes more sense for several people to share the kit.
