Does cupramine affect Seneye ammonis reading?

[Willbiker]

Hi! As the title says. Will cupramine affect the accuracy of my seneyes ammonia reading in my QT tank?

IDK, the literature says it measure ammonia, not ammonium, so it *should* be able to discern the difference. Can you make a spiked seawater sample and try it? That's what I'm doing with various copper solutions and my spectrophotometer - I just learned that Coppersafe is amine-based as well, and throws off my salicylate ammonia test.

I think it might work with cupramine - a few seneye users have run it with cupramine: @VJV, @Jon Malkerson

Chelated copper, however, I am not so sure about. I did some tests with copper power and it did affect the readings:

Anyone using a Seneye for active ammonia monitoring?

After getting over the shock of waking up to 100+ dead clownfish I would like to invest in an ammonia monitor. The seachem badges may be fine for 2 weeks of TTM but long term (months) they don't appear to work. I checked 2 badges and both check out good but given that all these fish were fine...

I did a quick test.

water before cupramine - 0.015 ppm ammonia
water after dosing 0.71 ppm cupramine - 0.015 ppm ammonia

Brilliant thanks for the info. Much appreciated !

I did this test with a seneye and coppersafe. Baseline ammonia: 0.009. Plus 1 ppm coppersafe: ammonia jumped instantaneously to 0.014. Dosed another 1 ppm coppersafe and jumped to 0.019.
I wonder if this is just an offset effect or whether this also affects the sensitivity to ammonia?

Is it an effect of pH?

Checked, but pH did not change.
