Hanna High Range reading 0

[KentuckyKobra]

Has anyone had any issues with the HR tester testing at a consistent 0?
I’ve had this tester for a year now and ever since, it’s always tested 0.

I don’t have my old salifert or Red Sea test kits any longer to double check and I would like to avoid going back to them. But that may change if my tester is faulty.

For a little background, the tank is a year and a half old. It’s a 150 gallon with 15 fish of assorted sizes. Before the Hanna tester, I was usually between 5-10 nitrates. My only filtration is a filter sock and Bashsea skimmer.

I have no hair algae, Dino’s, cyano, or anything like that. In fact, the tank is doing pretty great; Corals and coralline are growing and healthy and the fish are well I should also add that I feed quite often.


I’ve never had a tank with no nitrates before. Especially a semi mature tank like mine currently is. Do I even need to worry, or should I spend the money and get a different tester?

If so, which kit does everyone recommended these days?

Are you diluting it? Or full strength? Or both?

 

[KentuckyKobra]

I didn’t realize that you could dilute it? I just follow the directions to a T.

I misread anyway I thought it was the low range.

I was concerned that the test packets were expired and bought a new box. Still tested 0.

I like the high range tester. Maybe you’re actually zero.

Maybe I'm too new, but if literally everything is healthy and growing without any of the "bad stuff", than who cares what your actual number is?

Maybe it's 0 maybe it's 30 but your tank is doing what it's supposed to be doing.

Many systems (mine is one) run consistent zero NO3 (0.1ppm or below) unless I dose it.
If you care to know whether your no3 is really zero or just ~1ppm and not getting picked up by the high range checker, you'll need another test kit.

The risk of dinos is higher with undetectable nutrients, and it can be a serious problem that folks usually want to avoid rather than try to fix after the fact.

That’s what I’m worried about. I’ve been in the hobby for a long time and have battled Dino’s before when I had 0 nitrates. I’d like to avoid that problem this time around.
