Test Kits

when caught in the ocean everything is SW except aquacultured food fish
are generally
FW or FW/SW compatible like talapia which do well in both FW and
brackish/sw combinations


Humm.....
Guess I will be consuming more FW/Brackish fish and maybe caustean, too.

then again it depends on what you call aquacultured

if a big net in a bay is aquacultured then even more things are aquacultured which might
help you eat SW fish

I'll be short. :-) You will get a reading but it is not correct, just like a refract or a
pH meter or most pH kits. Did you know that a pH meter and most kits DO NOT test seawater
accurately . It is something we call the "Salt Effect". There are actual seawater stds for
pH, i.e, pH nist (FW) and pH nsw (seawater). Your pH meter actually reads to high just as
some test kits do. Randy will be doing an article on this later. We do not need to be all
that concerned for the meter ? Most given pH seawater meter values ( oceanography books,
articles etc.) are uncorrected. Some pH kits give you seawater corrections or are adjusted
for seawater. This is why some get confused when comparing kits. But they still sell them
now don't they for seawater. Same for the CO2 test kit, sold for seawater, IT WILL NOT
WORK PERIOD. Seawater is a unique medium and often messes up tests. As I have said a
meter measuring O2 most be correct for seawater and if it had such a correction where is
in on their website. Cheap O2 meters that use an O2 probe often give tables for
correction.

"And by using this meter to do an
aquaculturing or farming testing."

99 % of the time this is FW

"A normal person [non chemist] would assume this meter can be use to
test sea water parameter"

I agree. We have brought this up many times on our chem forum, go for a look. Randy has
NEVER said I'm wrong but wonders if it really works as claimed.

It is a photometer, works off of light, light does not travel the same in seawater as FW,
same reason a refract is off 1 unit right out of the box. But what do many of the websites
say. To measure salinity or seawater. There is only one refract on this planet that
measures seawater you can buy and costs about $400, all the rest or set to NaCl, which
again is not seawater. I also don't think much of Hanna they are a very bottom self
company. It was me that got their cheap ORP off the market they were selling to reefers,
as it didn't work. If you have any doubts call Hanna or HACH or LaMotte. Don't ask for a
lab tech either, they are usually brain dead, ask for the guy the designs and tests them.
I did and the answer was NO, not accepted for seawater, that was HACH and all these meters
work the same, they are Photometric colorimeters. Their meter also says seawater. Ask then
for a data sheet of a know concentration and how their meters compares, you won't get one,
as they don't have one


Here is a classic example. I did some private work for HACH years ago when I bought their
Seawater Aquaculture FF-3. I proved to them their CO2 kit can not work in seawater. The
guy that runs this section is/was Dave Corzat. I proved it, Frank Millero (this is who he
is http://www.rsmas.miami.edu/groups/jmc/fla-bay/fbay.html ) and Ed Mowka ( former
President of Aquarium Systems). One reason for you to see why it doesn't work CO2 Range =
10 -100 mg / l. You could not get 10 mg / l CO2 in seawater.let alone 100mg / l in
seawater.About the highest you could get is around 2-3 mg / l. Normal levels are usually
less that 1 mg / l NSW is 0.50 mg / l . How the hell can it do that when it must start
at 10 mg / l,..... 2 mg / l let alone 0.05 is waaaaaaaaaayyyyyyyy outside its range.

FF-3, Sal****er Aquaculture Kit 243003: Acidity, Alkalinity, Ammonia,

Thank Boomer. That link was WAY too long but I got to that link with your
above help.
http://www.makeashorterlink.com/
www.tinylink.com

I see the point, there is no meter or tool to accuately test seawater. But
at the same time, these tool like Photometer and FF-3, tell people to start
aquaculturing since the open sea is depleting. The main reason is about
light travel in seawater that cause the whole thing to be complicated,
unlike FW. I believe this what I understand. I am still assuming according
to those site and regarding to those meter for aquaculturing / farming.
Maybe a true experience chemist may use this tool and adjust or convert to
see the correct reading. Otherwise, if that tool in my hand, I would take
that reading as though it was correct if Boomer was not around to indicate
otherwise. Reason for this is that I *ASSUMED* since this was marketing on
their site or manual to imply *open sea depleting and use this tool to farm
/ aquaculture*. What else would a non-experience person use this tool for?
