Best Nitrate test around these days?

[sahin]

I have been very happy with my salifert. It gives resolution down to .5 or so if i remember right.

salifert for me.

I use salifert and although there may be better, all that I care about is clear, or barely blue.

Salifert and red sea have been good to me over the last few years.. Mostly Salifert just started trying the red Sea and I like it.. Matches up to Salifert so that's good enough for me.. And it's cheaper in the long run due to being able to buy the refills.. That I haven't had the need to yet..

I have used saliferts for a long time. It's really easy to read the low range (view from the side) test. Basically i can see .2 and 0 pretty easy and I am partially colorblind. Someone suggested the seachem nitrates kit since I started dosing vinegar and it does not work as well for color changing in the low range as the saliferts in my opinion. Kinda feel like I wasted that 15 bucks.

What is the digital on pictures above? How much and how accurate is it?

A+ to the Salifert.

I used a whole Salifert kit many months back when my tank had like 30ppm+ nitrates.

Salifert is very easy to see when you reach 0.2ppm. I saw my tanks reading come down and down. Now whenever I test it, its around 0.2ppm.

Euh... We are in the SPS forum here, i mean most of us want to have it close to 0. Or at least < 5 ppm.

All other things being equal, you're not going to be able to tell the difference between 2 ppm and 10ppm in any type of reef tank.

He asked for the best right? I don't think the salifert or redsea is more accraute then the low range no3 meter.

I bet the inhabitants of the tank will tell you though. I have a few corals that tell me when certain water parameters are off.

I am guessing that's a Hanna instrument nitrate test? How much does it cost? How repeatable are the tests? It says within .5 right?

 

[MarcWeaver]

The specs are confusing on the Hanna digital meters. They all say not for use on saltwater. What's the model number? I'd love to get one.

 

[Steveb]

Is that the Hanna HI 96728 photometer?

 

[tomae]

can it used in marine water? really?

I used salifert back when I tested for Nitrates. Havent done so for close to 2 years, as there was really no need to.
