   Um ... I have a Tang and he seems fine but now I'm scared.  How do
I ground my tank?  After I've grounded my tank how do I test its
groundedness?   Before I ground my tank how can I test its degree of
un-groundedness?

There's an idea!  Have you considered feeding cats to your

they will scratch you while putting them in the tank. ;-)

be that the dying bacteria would itself become a source of food for the rest

	I'm considering the big switcheroo- going from fresh to marine.
I'm actually interested in seahorses.  My question is what do I really
*have* to buy?, and what *should* I buy to accomplish this? Also is it
worthwhile for a 30 gal tank?  Currently I've an regular old power filter
and an air bubbler- along with the typical decorations-lava rock and 
ceramic 'cave'.  Can I use my current filter?  Most of the things I've
read don't really tell you things in terms of a freshwater tank and what
to do differently.  I don't think I'm ready to spend the big $$$ until I 
have more space for a really big tank  but maybe I can learn a lot starting
with a smaller one.
Any advice and e mail welcome

I would have to ask you seriously *WHY* you want to put food coloring
into a fishtank.  It will stain everything and cloud the water.

As far as harming fish, probably not *HOWEVER*, there is a caveat here.
Fish breath by passing water around and through their gills.  To put
foreign material like food coloring into the tank is inviting these
chemicals into the fishies resparatory system.  Why risk the health
of the animals that you have taken responsibility for?  It is your
task as a host for the fish to provide them with an environment in which
they can thrive and grow and live a happy life.  Dumping food coloring
into a tank would be like forcing you to live downwind of a toxic waste
dump.  You *probably* won't get sick, but do you really want to risk it?

I have my DIY ground drilled into the top of my power filter.  Since
the salt water conducts, and there's a direct water connection between
the tank and the ground screw (that is, the column of conducting water
in the power filter intake pipe).  It was just much easier to put the
screw in the top of the power filter than figuring out a way to hang
it over the edge and into the water.  Also, the water level in the
power filter box is almost constant, while the tank level changes with
evaporation and skimmer loss.

Even if the conductivity of the water is very low (acting as a
resistor in the circuit) the ground will be able to keep up with the
induced voltages in the tank.  It might not be able to handle a surge
if I dropped my light into the tank, though, if the water conductance
is low (resistance is high).

Part of the problem is trying to limit 102 fish to one half of a 55 gallon
tank.  There are too many fish in there!  Either move the babies to another
tank, or sell them off.  They can take of themselves by now, and have been
able to since their egg sacs disappeared.  With the number of fish you have,
you probably don't have enough filtration or aeration.  Before your fish will
get better, you need to go to the root of the problem.

Just one guys opinion.

   I have a f/w 29H tank with a Penguin 300 filter. I used to have 2 10g
tanks for over 3 years, and I moved up to a 29g. Anyways, after getting my
29g tank (about a year and a half ago), I noticed I had little snails
growing in the tank. Then I changed the filters and noticed that they seem
to like it there. I never noticed this on either of my other 2 10g tanks,
and I had Penguin filters on those as well. My question is, how do I get
rid of these little pain-in-the-necks. I hate them. I used this stuff
called "Had a snail" and that doesn't work. One time, I took my filter off
of my tank, filled it with steaming hot water, and a whole bottle of "had a
snail". It worked like a charm. 2 Hours later, I emptied out close to 100
snails. Where are they from? How can I stop them? What can I used to kill
them that is safe for the fish?

  I went with no stone on the end of my hoses for awhile, but found
that the noise drove me o'er the wall, so back on they went. The
makers of one brand of pumps that I have claim that the flow of 
water is the same whether there is a stone or not. An advantage
of no stone is that your pumps will last longer without them.

or the Iwaki rlxt (ie. 30rlxt) are circulation pumps they move a lot
of water as long as the head is low.  Other pumps like the little giant

The best way to measure the efficacy of various grounding schemes requires
two saltwater compatible electrodes.  Use one in the desired grounding
scheme, and use the other as a probe to measure the potential of the
saltwater at different locations.  Connect one electrode of the voltmeter
to the grounding electrode and the other to the second (moveable probe).
When you place the moveable probe into the water, the meter will read the
voltage built up across the water between the two probes.  This voltage 
should change as you move the moveable probe, getting small when the
two probes get close together.  If you still see a potential when the
probes are actually touching each other then this means you have magnetic
pickup.  this can be reduced by twisting the leads together.  

If you see a potential even when the probes are in contact then you
are not measuring the potential in the water.

I've got a 30gal tank that is currently using a standard-flow UGF for

the tank to add a tad of natural coral grooming (my substrate is
crushed coral).

The current occupants of the tank are a lion, a snowflake eel,  and a
very harried yellow damsel who happens to be just the right color so
that both the eel and the lion ignore it.

Am I considering doing something stupid?

P.S. I live near Half-Moon Bay in northern California,  and it is
     legal to collect shellfish and algae south of a particular marine
     reserve.  I'd like to start a second tank based upon samples I
     personally collect along the oceanfront,  but I'm curious -- what
