For Boomer re BioChem Zorb or other organic scavenger resins

[Phil Krasnostein]

Hi Boomer

See below.
Do you have any views on the ability of these resins to act as skimmers?

If you do a Google search for "organic scavenger resins" you will find
several references. This is what is referred to (amongst other things) on
the BioChem Zorb technical sheet. They seem to be in regular use in
pharmaceutical synthesis and water treatment. It has really made a big
difference to the appearance of my tank and tonight I'll measure the N03. I
would still like to get a feel for how much carrying capacity the material
has -- i.e. how much N03 can a given quantity of resin hold?? Maybe Boomer
can help??

First, I don't believe much in hype :-) Some of the components in this media are ionic
exchange resins. I'm still waiting for AP or any of the aquarium companies that use an
ionic exchanger in seawater, be it a resin or zeolite how the hell it can wok, with a
gazillion ions to exchange with in seawater. One of the most common ways to recharge some
of these resins is in a "salt solution". Hmmmm, no where have I heard that phrase before ?
It you called and asked a ionic exchange resin chemist, that makes such resins, that you
want a resin that will remove nitrate in seawater, he will pretty much start laughing at
you remark. I know, been there done that, just to make sure I was correct years ago. The
same goes for zeolites and so called nitrate sponges. And a nitrate sponge ( a zeolite
called clinoptilolite) is exactly the same thing as old fashion kitty-litter or floor dry
or FW ammonia remover. As far as this statement by AP " removes organic waste, toxic
gases, water discoloration, foul odors and phenols in both fresh and sal****er, and toxic
heavy metals in freshwater", activate carbon alone does all this. I also really get a
charge out of this when I see it, of course only on aquarium products "research-grade &
pharmaceutical-grade". There is no such things as these grades, accept those applied by
aquarium companies, it is a line of BS on their part. If one had access to a chemical
supply catalog or looked for one on the net, these name to do not exists. Grades names
are; PS ( Ultra-Pure), ACS, Reagent, CP, NF, USP, Food, Lab, Practicle/Pure/
Purified and Technically. There are also a couple of odd-ball grades. However, they may
be trying to say they are using UPC and calling it as Pharmaceutical grade. As far as
Research Grade pick one of the above and it sure as hell won't be the first 3 or even
maybe the next 2. If so, why not use the real name ? Most of these resins and zeolites
are all designed around FW and seawater is a different beast complexly. I also don't by
the words "seawater or salt water", often taken and used improperly, they are ill
informed , don't know or are trying to BS you. Examples; HACH makes a test kit and puts
in their sal****er.seawater master kit for CO2. You CAN NOT MEASURE CO2 IN SEAWATER WITH A
TEST KIT .......PERIOD. Refractometers for salt water, salinity, seawater use. Not so.
Only one company on this planet make a refract for seawater, the rest are all off .15
units to low, as they are calibrated to table salt and not seawater, which does not
refract the light the same as table salt
