How To Test For Copper In An Aquarium (2018)

Okay so in one of the Facebook groups I
think it was or maybe it was in the comments on one of the other YouTube
channels somebody asked what kind of tests do you run on a shrimp tank and a
couple of people mentioned copper testing and it got me thinking you know
copper testing is not a bad thing since shrimp are so sensitive to copper but
I’ve never actually tested for copper, so I went online and I bought the Seachem
copper test kit because seachem is a company that I kind of trust as far as
chemicals go, so I’m gonna give this a try So older houses by that I mean
anything older than a couple of decades have copper piping and that was one of
the concerns. What happens when you use tap water and you’ve got copper pipes, and even
more so what if you’re using the hot water? Hot water sits in most cases in
North America anyway, hot water sits in a heating tank for a long time. That heating
tank is filled with copper pipes your water’s just picking up more and more
copper so I’m gonna test my top water as is, just as it comes out of the tap with
this test kit. I’ve never actually used this test kit, so it’s going to be interesting. So it comes with this copper reference I guess for calibrating comes with a little
pipette comes with this little tray for six
different samples and this little stir stick and with a bottle named copper
number two which I’m guessing is the test fluid, and this little thing full of
white powder. So let’s look at the instructions and then I’ll come back and
we’ll test the tap water. Okay so I filled a drinking glass with water from the cold
tap now the instructions say to take the pipette squeeze it and fill right up to
the bottom of the bulb and then squeeze that out into the tray and then do the
same thing one more time so that’s two pipettes worth water then two drops of reagent number two then it says take the dry stir stick and open up the little powder which is
reagent number 1 don’t ask me why you do two before one but that’s what the
instructions say so that’s what we’re doing might be a little bit difficult to get
the cap off reagent number one but there we go so it says to just dip the dry
stir stick into there and shake off any excess you’re just trying to get a
little bit on it and dip it in and stir it and then we wait four minutes. Okay so
after four minutes you’re supposed to compare it with this chart now they give
you a little sleeve that you can slide the chart through so that it makes it
easier to compare the blue of the water with the blue on the chart and you just
want to find the closest shade to what your water is I’m going to say it’s
right about there that says 0.1 for my water 0.1 for the cold water I’ll do another test
with the hot and we’ll see with that clean wait so I don’t know if you can
see how blue those two samples are because they’re still very very light
but it looks like the hot water is just a little bit darker blue I’d say but 0.15 or the other one was 0.1 so at
least in this particular case and only one test done I would say that yeah
there’s probably some truth to the fact that the hot water because it’s sitting
around in the hot water tank does pick up a little bit more copper than the
cold water neither one of these is high enough according to the information that
came with the kit to be a problem in most freshwater aquariums
they say 0.5 you would want to start diluting it down with RO or distilled
water but we all know that shrimp are a little bit more sensitive so maybe tap
water isn’t such a good idea for them maybe using RO and remineralizing is a
much better idea than using tap water anyway at least if you’ve got a house
that’s older than a couple of decades anyway when they started using plastic
pipes instead of copper you know that’s it for now if you liked this video go

have maybe give it a thumbs up let me know that you liked it okay talk to you


  1. Hi all.. I treated my fishes with cupramine., wen they are infected with ich… And I got succeeded in doing it.
    Have a look

  2. Hi buddy are you sure it’s two pippets of water. If that what that means in the instruction then that’s not very clear : “fill sample pipette to base of bulb . Repeat adding to same cavity “. Why does instructions not just say add 2 pipettes lol. I’m glad I watched your video. I just got the test kit so I think I did it wrong cheers
