p.s. Jaime, on your website you claim you specialize
in wildlife field research and your research resulted
in "numerous publications". Could you provide a list of
your publications here ? I am interested in reading them.
Thanks.

NO2, NO3, PO4, KH, ORP, Ca, SG/Temperature...
All this parameters alone say little about a tank. I put them in an Excel
chart and after normalizing them I got pretty interesting graphs
The 10 points aquarium checks are found in
http://www.guayni.com/Maintenance.htm
A complete service with an hour of tutoring costs $65
As for my publications, I am working on some details before I web-publish
them, they will be available for download. Basically, some of them are not
only mine, there are others and using them for business takes a little
negotiation with my colleagues. There is another little problem; some of
the findings used for my WRU are confidential until I patent the filter.
Nevertheless, I will provide a copy in pdf of the more interesting ones.
Most of them are of wildlife nature in the Florida Keys and the Central
Florida Wetlands.
My publications should not be an obstacle to those who want to see another
angle of the water they have in their aquarium...
I do appreciate your concerns and hope you visit my website again, some of
the graphs I am getting will be published and establish a relationship
between parameters worst noticing.
Thanks again, Jaime

I wish ya the best of luck mate!!
The leaning towards teaching people...... tis always the best of signs.
Sounds like a pretty wacky filter, will be good to see it in a marketable
form!
Bit of everything thrown in, a frankenfilter.

Looking at you chemical measurements it DOES NOT WORK

There is no room in a reef tank for a fluidized sand bed filter.
This kind of filter is good for a swimming pool, but not in
a reef tank, where it quickly become a nitrates factory.

Nitrogen Cycle.
Ammonia is the most dangerous form of nitrogen in your tank. It gets
oxidized to NO2-(nitrites) by bacteria. The sole presence of nitrites is a
direct indicator that your bacteria is oxidizing Ammonia since it has no
other substantial way of entering your aquarium.
Nitrites get oxidized even further and converted to NO3-(Nitrates)
If your system is low on Ammonia and Nitrites then your bacteria is
oxidizing it to Nitrates.
A nitrates level of higher than 1000ppm is needed to cause death to your
fish. Nevertheless a high concentration (100ppm) will have a direct effect
on your fish's metabolism.
In other words, the job of your bacteria ends there, for Nitrates to be
reduced again to nitrites requires low levels of Oxygen.
Many aquarists remove Nitrates by means of water changes. I chose to remove
it by harvesting algae and by creating a nutrients sink where Nitrates are
confined to a specific place where they feed my algae to be harvested. Is a
principle learned in a Wetlands Ecology class. Is the same principle
mangroves in nature and drainfields in households use.

I agree :-) You have still a lot to learn...

Any ammonia which is detectable with aquarium-grade tests
in an established aquarium tells you one of the two things:
- your test is wrong/faulty/old/missused
- you have something big and freshly dead, decomposing
In a healthy&cycled tank any amount of ammonia produced by
fish is QUICKLY eaten up by 1st group of bacteria, which
use ammonia and convert them to nitrites. No ammonia should be
detected in the water using usual aquarium-grade tests
because all is quickly neutralized if the biological
filter is working properly...
Simple way to check your test is to measure ammonia level
in a freshly mixed saltwater, there should be no detectable
ammonia there. The same applies to nitrites, of course.

Detectable nitrites are also strong indication of
INSUFFICIENT action of the second group of bacteria:
these which take nitrites and produce nitrates...

0.50 mg/l of ammonia in an estabilished aquarium is HIGH!
It usually means that you can find dead fish in one
of the fish tank corners... These are the levels which
should NEVER be detected in a healthy fish tank...

And because we do not want nitrates affect our fish we
strive to keep nitrates BELOW 10mg/l, preferably even
lower in a healthy reef tank (1mg/l and lower if possible).
Using SEACHEM low-range nitrite/nitrates test on the water
from my reef tank I read both nitrite and nitrates 0 mg/l.
Of course it does not mean 0.0000000 :) it simply means they
are below detection limits of the test. First pink color
on the scale is way below 0.1mg/l so I can say nitrates in
my reef tank is at 0.1mg/l or below - this is dirrect effect
of deep sand bed (DSB) and anoxic layers deeper in this sand
where denitrification occurs in my tank.
The problem is usually with phosphates, which in my tank
(with quite heavy cyanobacteria activity eating phosphates up)
is still above 0.1 mg/l PO4: reading 0.18 mg/l on the HANNA
INSTRUMENTS low-range phosphates photometer/colorimeter (+/- 4%)
My goal is to have them below 0.1mg/l with no ugly cyanobacteria
activity helping to bring it down.

The problem is (and you are obviously unable to grasp it) that
nitrates at a level of 50 or 100mg/l are simply NOT TOLERABLE
in a helthy, good looking reef tank. Period!
Reef tanks require the cleanest water possible in aquarium trade!
In the tropical reef waters in the ocean, nitrates level is
usually between 0.1-0.3 mg/l. Let's round it up, generously
to 1mg/l - your tank have 50 or 100 times more nitrates than
the reef water in the ocean. Inorganic phosphate levels are less
than 0.3mg/l with dissolved organic phosphate less than 0.15 mg/l.
If you want to bring your magical filter to the reef tanks market
you need to show that your method keeps phosphates and nitrates
under the levels accepted for a reef tank: 0.1 mg/l and 5 mg/l
respectively.
Think about the problem areas in your tank and come up with
a solution to each of the problems:
- high ammonia (any detectable ammonia in a cycled tank is a concern)
- high nitrites (any detectable nitrites in a cycled tank is a concern)
- high nitrates.
Think of it as your homework to do before you come back here
and repeat your preaching about your magical filter... :-)

I don't see any disagreements between your views and mine.
NH3>NO2>NO3 in a danger gradient.
I just have to add that if anyone is going to try to duplicate in-vitro what
nature has in-situ better has his/her pocket full of cash.
The beauty of this hobby is to try to create something similar in his tank
but never will be able, no matter how much money they put into it, to
re-create a piece of the ocean in a glass tank.
There are obstacles to overcome this but many had come with some pretty
remarkable ways to do it.
Unless you put diapers on your fish, they will continue to pee in your tank.
That ammonia and other nutrients will build up in your system.
I think I found a tolerable level were the fish does fine.
N and P are being removed from my tank without expensive investments. They
may be high under your standards but I chose fish that can tolerate those
levels.
Happy new year.

The problem is, that your levels are "tolerable" for fish only
systems, not for reef tanks - do you understand the difference ?

Could be other things. Basically, it means that amino acids are being
broken down into ammonia faster than the Nitrosomonas bacteria can
handle it. This could be caused by simply added more fish to quickly. Or
some of the bacteria dying off due to someone putting antibiotics in the
tank, etc.

Not true at all. There are many things other than the end product of
Nitrosomonas that can do this. I once saw a tank deliberately sabotaged
by someone pouring in a foreign substance that was pretty much 100%
nitrites (pentobutyl nitrite, to be specific) Easy enough to come by if
you know what it is sold/used for.
Iron hydroxide. Specifically, RowaPhos, is good for this. Other products
that are based on iron hydroxide work well too. (phosban, etc)

Then he should have learned about the anaerobic phase. Dig into the sand
on the beach at low tide - that black smelly sand you find below the
high tide mark is laden with bacteria that break down nitrates rather
nicely.

who needs it? I have 0/0/0 ammonia/nitrites/nitrates in a 20gal nano
with basically just live rock and a deep sand bed for a filter. No sump,
either. (biggest issue is evaporation and salinity, and keeping the Ca
and alkalinity up)

Frankly, I only have fish in my tank to create fertilizer and crop the

100 is in the deadly range for a reef tank. One aims for 0 nitrates in a
reef tank. one can get by having readings of 20-30 on a constant basis
for a fish only or fish with hearty invertebrates type system. But not
in a reef tank.

Um, "nitrates reduced again to nitrites"? !?!?! Huh?
Given that you mention "low levels of oxygen", I assume you are
referring to anaerobic bacterial activity reducing nitrate levels? That
process takes nitrates and converts them to either amino acids (less so)
or atmospheric nitrogen more so). NOT nitrites.

It's called a refugium. Nothing new.
Would it suprise you that my tank has no real filter to speak of (hang
on power filter basket has only rubble rock in it - no foam filter, no
chemical media) and yet all my nitrogen related levels are 0? (0
ammonia, 0 nitrite, 0 nitrate?) And I manage that with NO refugium, no
sump, and absolutely no macro algae at all in my tank.
Properly set up modified berlin systems (live rock plus DSB) are the way
to go for reefs. No doubt about it.

Actually it's converted to nitrites, and then the nitrite
is converted to nitrogen gas. So yes, incomplete
denitrification can convert nitrates into nitrites.

Let's not make a bigger mess in terminology... please.
Let's not call system with DSB a Berlin method!
Berlin method since forever was bare bottom method.
DSB is just deep sand bed method, not a berlin at all.
Deep sand beds are not very popular in Europe anyway.
Not big market for live sand dug from the reef and
shipped wet like live rock - this is popular in USA mostly.

So, why do we get a conversion of nitrites to nitrates? Seems to me that, once
an organism develops that converts nitrites to nitrogen, it would replace the
bacteria that convert nitrites to nitrates.
Hey, maybe it does. I suppose you wouldn't really know what's going on once all
the levels are 0.

nitrite, and in an oxygen environment bacteria converts
nitrite into nitrate.
In a low oxygen environment bacteria converts nitrate into
nitrite, and in a low oxygen environment bacteria converts
nitrite into nitrogen gas.

Isn't that contrary to the laws of entropy? Going from a lower state to
a higher state? I will need to research this, since energy would be
required to un-oxidize nitrite. Any references?

Indeed energy IS required. I don't understand why you think that would
be an issue? the bacteria doing the reaction obviously provide it. MOST
biolgical processes use energy...

OK, did a little research, and here is what happens:
Nitrate is reduced to nitite by the enzyme nitrate reductase.
Nitrite is then reduce to nitric oxide (NO) by nitrite reductase.
Nitric Oxide is then reduced to Nitrous Oxide (N20) by nitric oxide
reductase.
Nitrous Oxide is then reduced to atmospheric nitrogen (N2) by nitrous
oxide reductase.
So, it goes like this:
NO3-->NO2-->NO-->N2O-->N2
<singing>
We got to... eliminate the oxygen... accentuate the nitrogen
</singing>
So, while it is correct to say that nitrate gets reduced to nitrite in
an anaerobic environment, that is in fact only the first step in a chain
that eventually leads to N2.

Maybe you enjoy corals only with a few fish. The majority of people in this
group enjoy the fish as well and developing a coral reef system with its

You can MAKE them interesting by posting fish-related articles
and helping people interesting in fish-only setups...
There is a place to discuss your fish-only filters and other
fish-only related methods NOT SUITABLE for reef tanks...
Posting fish-only subjects here CONFUSES USERS who might
think WRONGLY they apply to reef tanks, as well...
As we all discovered, perfect example is your "magical filter"
which helps you "lower down" nitrates to very high levels as 100mg/l
totaly not suitable for reef tanks.

So following your logic, if we all enjoy sex, should we

we stick to the dedicated subject, which is REEF TANKS ?
