I have fish in my tank and I don't use any mechanical filter other then
my pre-filter.  If it is not for the fact that the spray bar will get
clogged, I would remove the pre-filter too.  I went out of my way to
remove as much mechanical filtration as possible.  Polishing sponges and
floss packed in a canister filter is far far far more efficient in
turning ammonia into nitrate then bio-balls.

That may be true if you have a fish only tank.  In a reef with enough
LR, nitrate can be driven below .25ppm by regular cleaning of pre-filter
(and removal of all other mechanical filters.)  My theory on that is of
course, LR are so much better at turning ammonia into something else, a
trickle filter is nothing more then a good conversation piece (and a way
for a lot of people to make a lot of money, along with O3 injection,
etc.)

  Thanks to everyone who replied to my "problem" message about my
dying corals.

I had my water tested by my dealer and it turned up 80-100 ppm nitrate... not
good at all.  The tests also revealed a defective test kit at my end.

The problem has been solved, and the corals already look better.

Your snails are invertebrates.  I am amazed that they did not
die immediately.  If nox-ich uses a copper compound, the Cu will
bind with the gravel in your tank - each time some Cu is removed
via a water change, the Cu bound with your gravel will re-dissolve
into your water - this is my guess as to why your snails continue

Subject: Help me identify my fish, and their problems ...

So, I have this tank of fish.  I bought them in a department store pet
shop, and they weren't clearly identified as anything other than
"Tropical Fish", so I thought I'd ask here if anyone can help me
figure out what they are....

There are two that I know are White Clouds, and one Cherry Barb.
There's another fish that looks a lot like the Cherry Barb, except
that it's sort of a yellow color.  And there are two others that look
a bit like goldfish, except they're a sort of translucent silver
color, with a dark stripe running down their sides - they also chase
each other around a lot, if that helps to identify them....  :-)

The little yellow one that looks like the Cherry Barb seems to be
having a problem.  If it were a person, I'd say it seemed depressed,
but it's a fish, and I don't know if fish have emotional problems....
It spends most of its time hanging around the bottom of the tank, near
the glass, as if it were looking out into the Big Wide World.  When
the translucent silver fish chase each other around, sometimes they
bump into this fish; it hardly seems to notice.  It's not eating very
much; usually, by the time it realizes that there's food in the tank,
and that it's hungry, the other fish have eaten most of the food, and
it can't find anything left to eat.  I'm not sure what this fish's
problem is, or what I can do about it - I'm afraid it's going to
starve itself to death.  It's been doing this for about three days
now.  Any clues?

carefully cleaned out the tank. I noticed the shell for my blue
knee crab and picked it up. To my suprise IT WAS EMPTY!!. I can't
see him anywhere in the tank (of course I can't move all the rock
either) it's been 1 day now.....????????????? where did he go???
any ideas. Is he dead maybe?? why would he abandon his shell??
I have other shells in the tank also, which are empty...

I have three fish (one goldfish and two zebra danios) that I need to take 
home for the holidays.  I would rather not move them but since there would 
be no one here to take care of them, I can't leave them here for three weeks.
I am planning on putting them and their water into a few clear 1-gallon
jugs (with the lids off of course and lots of air in the jug) and transporting
the empty or near-empty tanks separately.  I figured that the small openings
of the jugs would prevent much water or fish sloshing out as opposed to 
leaving them in their tanks and moving them that way.  

It's only a two-hour drive but I *know* this will put a lot of stress on the
fish and that it's not that good of an idea to begin with.  Does anyone have 
any suggestions on how to make it less stressful for my fish and if this setup
is a good idea?

The fish and I thank you in advance!

-> 3 weeks ago, I went to the local pet store and came home with 5 fish
-> recommended by the storekeeper:
-> 1 M betta
-> 1 F betta

First of all, I have to ask: has the male betta finished killing the
female yet?  That pet shop owner was apparently either extremely
unknowledgeable about bettas or else was only interested in making
money. I wouldn't spend money at that petstore ever again, if I were
you. The reason is that bettas should be kept singly unless you are
attempting to breed them or stage spectacular fishfights for your
friends to bet on. Breeding bettas is pretty complicated, and you don't
just throw a male and female into a small tank together without
expecting a lot of frayed fins and probably the death of one of the
fish.  They have to be kept separated by a partition in the tank until
they get used to one another and exhibit signs of being ready to breed.
 I don't think this is what you want to do in a beginner's community
tank.     My advice would be to take the female betta back to the
petstore with a reprimand to the owner for his lack of knowledge and/or
unscrupulous sales tactics, and demand either a refund or some more
suitable fish for your community tank.  Keep the male betta. He's fine
as long as another of his kind isn't present.  Get something else like a
couple more tetras of some type.  Also try checking a book out of your
library on tropical fish and aquariums, so you won't be so much at the
mercy of petstores that only want to take your money.

I must disagree.
I have kept males in community tanks for quite a while (one male at a
time, of course), lately (for over a year) with females. They are happier
with two females, but even with one, I have had no trouble with untword
aggression. A bit of fin nipping, perhaps. but that is all. Of course,
they have not bred, but I don't expect them to. These are community tanks.

Hi,

I recently  bought a La Mer Series 4000 protein skimmer.

I  also bought a 400 GPH external  pump to drive it.

The 4000 series is designed to either work in the sump or out of
it.

Basically, the water  from the pump gets forced thru a venturi  valve
(pat pending)  where it is mixed with air  from a strong  air  pump
(I have LUFT g)  and forced into the  reaction chamber.

It is supposed to be simple to adjust, but I  don't really know if  I have it right.

If, I change the amount of water delivered from the pump, I can also control the amount of foam produced.

I keep thinking that I should be seeing some sort of brown gross sludge in the collecting cup, but I really dont
see a whole lot.

Does anyone have any advice on adjusting this gadget, or my expectations ?


Thnkas,

Now this is what I don't buy concerning W/D trickle filter -- that they can
