Marine Discussion: Test Kit Safety

[beviking]

...Compounds which interfere with test:
Silicate if present at concentrations greater than 350umol/L (about 32ppm) and/or if left standing for more than 5 minutes

Arsenate, but unlikely at natural concentrations

Hydrogen sulphide, if greater than 60umol/L (about 2ppm), requires anoxic conditions.

NO3 if around or greater than 124ppm, but you've got bigger problems then!

Also, high copper content (more than 160umol/L, about 10ppm) will reduce the colour....


h.c., do these compounds interfere with all tests or just those listed above respectively?

[happychem]

No, those were specific to PO4, I did list interferences for some other tests, I'll bold-up the fonts for the individual tests.

I have the Aquarium Pharmaceuticals Freshwater Master Test Kit, plus a few others, and I do have to admit I've burned my fingers a time or two with the acids in the kits. It wasn't serious either time, but I did wash my fingers well with cool water once I realized what was going on, and everything was ok.

[happychem]

Hehe, I've dumped enough different acids and solvents on my hands at one time or another to understand that! Working in a lab is hard on the hands!

And the clothes unless you have scubs provided.

[happychem]

Yup, lost a good shirt to some HNO3

Don't forget about the dangers of mixing chlorine and ammonia:

Look here (http://www.bbc.co.uk/dna/h2g2/alabaster/A795611)


When people cycle their tanks using ammonia, watch where you keep your bleach.

^&@# They changed their links. Maybe an edit is needed.
