they just happen to be on sale at the good Drs F&S for about 170 bucks this week. the test reagents (not included with the meter) are 20 bucks. after about 200 tests the per test cost drops considerably compared to say a Salifert kit. it's allot like a calcium reactor, you've got a hefty up front cost but long term it's cheaper.

I'd be happy to do the tests with any other media if someone wanted to provide the media for testing, I've got another system with a 100g system volume that's at 0.9 currently.
I've also thought about getting some of the AZNO3 to try out on the above system, it's keeping steady at 23-25ppm NO3, if i do, i'll post the results of that too.
