Test Kits

[George Burnt]

Hello,
I do not have the best eyesight in the world, so every test I do seems way
off according to how I read the colour charts. Last week my kit and my eyes
claimed that I had a PH of 1.2. Now I know this had to be wrong as my hand
did not disolve when I put it in the tank, so I bought a PH meter and it
recorded a ph of 8.2, which is OK. Is there such a thing as a digital
calcium meter and what other meters would be useful to me? I have found
temperature meters and ORP meters. By the way what is an ORP meter?

So far I only have fish with base rock, and it has been doing great for four
years, but now I want to take the plunge and go reef. I already bought the
MH lights, next will be all the meters, then a dsb, live rock, then the
inverts.

I am getting the order of things right?

Yeah,

I have been considering it as well.
Will work fine so long as sea test and fastest regent kits never change and
the colors they produce are not messed with.

I too have difficulty with colors..

I would bet that the regent company would love the creation of this product.

I was talking about the first one...
That one is way outside my budget..

"I have been seriously considering this one:"

I wouldn't, as there are NOT accepted for seawater. These are FW photometers and the high
salinity of seawater skews the results. Known has ever done anything on any of these units
and compared to NSW with, a known concentration.

How interesting though, Boomer. It is funny when you mention this
"photometer" are FW meter but according to their site, it statement focus on
sea critter for aquaculturing. Since I do not have any experience with this
meter nor can I ever to afford it. But Boomer, do you have experience or use
with this meter?

I don't care what their site says, it is a common mistake. All one has to do is call HACH,
one of the worlds leaders on these units an ask the guy that designs and makes them. He
will tell you no. It is not that they won't work, there are no std's to judge them buy.
More than likely a conversion number will be needed to calculate in, to adjust for
seawater. That's what they asked me to do when I asked about their Nitrate photometer a
few years back. You need a known concentration and tested at different salinities, to see
how it is skewed. I never did it, as they wanted me to BUY the meter to run the tests !!!!
Saying a meter or test kit works and showing it actually does are two different things.
Some companies make CO2 kits and say that they work in SW, which is absolute BS and I
proved that :-) You have to remember that these units work off of light and light does not
travel the same way in seawater as FW. Think refract and how they are off 1 unit to low
right out of the box. The are calibrated to NaCl, which is not NSW. NSW has a higher RI
(Refractive Index) than FW. Here is an updated std Randy and I worked on

If you want an S=35 standard for refractive index, try 3.65 weight percent NaCl in water


NOTE;

It is not 3.5 but 3.65. A 3.5 would be for pure NaCl, how the meter comes in the box

I forgot Cap.You mean that website posted, where does it say Hanna says that on their
website seawater ?

http://www.hannainst.co.uk/catalogue/it070012.htm

I would also like to know how this unit can measure DO without out adjusting for Salinity
and barometric pressure. Neither are listed. If it has such a salinity adjustment it would
say so, as all meters that do say so.

Here is more info on it .Nowhere does it say "seawater"

No not seawater. The AquaStore just simply using a generalization or imply
that fish is depleting from the open sea. And by using this meter to do an
aquaculturing or farming testing. So from this statement, I HAVE to ASSUMED
that this meter can be use for testing. Kind of missleading.
http://www.aquanet.com/paq035.asp
BTW, where majority of fish come from. I assume catching from the sea. Do we
catch fresh water fish? Well yes, but not much. Majority of the catch is at
sea. A normal person [non chemist] would assume this meter can be use to
test sea water parameter.
Quote:
"Research personnel, fish farm operators and wildlife specialists now have
one compact and easy-to-use meter to keep a close tab on the most important
parameters in aquaculture."

What this implying? We only can assumed here. It does not really say
specifically for sea water.
Quote:
"With the ever-increasing depletion of fish stocks in the open seas,
aquaculture has gained prominence and can prove essential to our future
dietary needs."
So anyone that want to do a fish farm or aquaculturing, do they start fresh
or sea type? Again, my brain start to assuming, it gotta be sea water type
of fish.

From Hanna site -
http://www.hannainst.com/products/ion/c203.htm
AquaStore using the statement from Hanna site but omit some small detail
like "pond".
It is interesting how Hanna start from how fish is depleting from open sea
and need to aquaculturing then next use pond water to test.

So what this meter is use for if not for testing sea water parameter?
I am at lost here. 8(. Boomer, I know and hearing from you that there no sea
water standard to go by or no meter available to accuately enough to be test
with. And yes, Hanna site does not that I can find anything specific that
indicate to test sea water regarding using this meter.

fishing is depleting from the ocean

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

except its not implying much. all of the 3 fields do work in both FW and SW

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 :D

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.

Thank Boomer. That link was WAY too long but I got to that link with your
above help.

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?
