Test Kits

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.

Anyone have or use this unit?

I have been seriously considering this one:
http://www.aquanet.com/paq035.asp

Seems a bit pricey, as my regular test kits have been sufficient but I
can't see how you could get anymore cool. It would sure blow away the
strips my LFS uses.

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?

CapFusion,...

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 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
