        is it due to water temperature, light, etc...

Okay now you either added makeup water from the tap or you mixed some
new salt water from tap water and did a water change right; you didn't
replace saltwater with fresh tap-water right?

I bet the tap-water is your problem.  Get a DI unit (or RO) and filter
your source water.  I had the same 'brown-yuck' problem you did till
I started treating source water.  

Also, you might not want to use water from your hot-water heater.
I've heard it can add stuff.  Use cold tap-water into some treatment
devise (RO or DI) and mix you SW change water in a bucket and let it
age for a day or two before changing.  This process will allow gases
to balence and allow the water to warm up.  Use a small aq heater
to get it to the proper tempureture if you have to.

i'm having problems with a strange kind of algae in my reef setup:
it's a 60g tank with just a venturi protein skimmer.  i use chemipure
and polyester filter floss for mechanical filtration.  lighting is
the dual 175W 5500K MH and two 40W actinics.  the temperature is kept
less than 80F.  the tank had about 2lbs/gal of live rock.  there is
only several soft corals and some sea urchins.  i don't feed this
tank at all.  this tank had finished cycling about 3 months ago.
everything looked like it was doing fine until...

i had just added a large rock of mushrooms corals from an aquarium store.
and then performed a small water change (with warm water from the tap).
after this i got a bloom of some strange looking algae.  the urchins were
all fine but all my snailed looked like they were dying.  i checked ammonia,
nitrite, nitrate, kH, and pH; they were all very normal. the algae looked
slimy brown and covered my macroalgae, rock, and tank.  i thougth it was
cyanobacteria so i gave a 1/2 dose treatment of maracyn 1 (the one with the
eurythromycin).  (i removed the chemipure and turned off the protein
skimmer.)  after a week of this treatment it still hadn't gone away.
next i turned off my lights for a few days and i'm waiting to see what
happens.

the suspected causes:  the rock with the mushroom might have carried it.
maybe it was copper or some other heavy metal in the warm water i used
in the water change.

i would be interested in hearing any suggestions on how to get rid of
this algae.

  I have a question concerning the feeding of my Starflake Moray.
 Is it all right to keep him on a diet of exclusivly goldfish?
 I've had him over a year and he has grown from 3" to 12". I give
 him one 1" - 2" goldfish a day. About two times a month he will 
 not eat for about 3-4 days. When he does eat, he eagerly accepts
 the goldfish from my hand. 
  My reason for concern is that he seems to have stopped growing.
 I have not noticed any growth for the last 2 months. Also he hides
 a lot more than he used to. Usually he would prowl the tank starting 
 about 8:00pm (1 hour before 'lights out'). Now I only see him at 
 feeding time.
  Water conditions have been stable. The tank is a 30 gallon. He is
 the only 'fish' in the tank. 
  Any comments or suggestions would be greatfully accepted.

As part of a fish simulator I'm writing I need a relatively scientific
definition of the term "water hardness".  If someone could help me with
the following, I'd appreciate it:

	* Define it?  What are common level ranges?
	* What most directly effects this value?
	* What effect does hardness level have on fish living in the 
	  water?  (Somewhere I've gotten the idea that fish won't mate
	  in certain water hardness levels.)

This will help me alot.  Thanks.

I just added a Gar to my tank the other day and it's behaving strangely.  He
just floats at the top of the water.  He doesn't have any trouble swimming or
diving though.  I thought it may be a swim bladder problem but I'm not sure. I
understand that the swim bladder of a gar is different than that of other fish
(an auxiliary breathing organ).  It hasn't eaten for several days.   

Need help.

My yellow tang also developed the same symptoms in the past, but the
cause was definately non-organic.

In the evenings, when we turned the room lights off, the tang would
sometimes become quite agitated.  He appeared to be fighting his
reflection on the surface of the glass...I could not tell whether the
red marks were "bruises", warning marks, or from high blood pressure :-)

Whatever the reason, the marks gradually faded after we started leaving
the room light on while the aquarium lights were on.  (Letting some algae
grow on the glass also seems to work, but isn't an ideal solution).

This sounds like lateral line disease.  What were the areas affected on
the tangs?

	What exactly made you conclude this? I had my Tang develop red
streaking/blushing around the fins and extremeties this summer. My guess at the
time was that the water temperature was to blame, since the summer heat had been
pushing it up that week. As soon as the water temp. went down a bit, the red
started to disappear. I didn't add any medication or change anything (except I
suspect I did a water change of 10% or so, that being my standard response).

Subject: [F] Success with Algae Destroyer
Organization: Hewlett-Packard Co., Loveland, CO
Newsgroups: sci.aquaria

An update on our attempts to deal with a bad case of "beard algae".

This type of beard algae, at least in our tanks, is bright green and
grows mostly on plant leaves.  It gets to about 1" (2.54 cm) long and
tends to look like long, green velvet.  It "blows in the wind" like
fields of wheat.  It is impossible to mechanically remove from the
plant leaf, unlike "hair" and "thread" algae.

The "Algae-Destroyer" product worked for us.  It is made by Aquarium
Pharmaceuticals and comes in tablet or liquid form.  It seems to be 
available at most fish and pet shops for $4-6 for 18 tablets (treats
90 gallons of water).  It's active ingredient is "Simazine".

We used the tablets at the recommended dosage.  We treated once,
changed 50% of the water after 1 week and treated again, also changing
the water after 1 week.  This cleared up the "beard algae" but had
little or no affect on red brush algae (black tufts) or the easily
removed hair and thread algae.

The treatment had no apparent affect on the fish (Melanotaenia, Corys,
Pekoltia, Farlowella, Ottocinclus) or most plants.  Only Nomaphila
stricta (temple plant) was adversely affected (as in, it pretty much
all died).
 
As a side note, a friend mentioned that Siamese Algae Eaters
(Epalzeorhinchus siamensis), a relative of Flying Foxes, snarfs up red
brush algae like crazy in his tanks.  We haven't had that experience,
but then, we tend to feed our fish and he dosen't.

Subject: Sick angelfish: Help!
Date: 11 Jan 93 01:04:35 GMT
Organization: The Great Beyond

Hello..  I've got a tropical tank, and a couple weeks ago I noticed my
angelfish had a white growth near its mouth.  It was pretty small and I
assumed it was ick or some fungus, and I added a bit of anti-fungal medicine
to the water.

Over the next several weeks this began to grow.  I continued to add the
medicine somewhat regularly, although not in great amounts since I was
worried about hurting the other fish or plants.

But as of the past few days, this white growth has grown and if you look
at the fish, it looks like it's not on the exterior -- it's on the interior,
and it's kind of deep.  Tonight the angelfish doesn't seem his/her normal
self, and it looks like there might be small spots of white on other parts
of the body.  The eyes are bulging a little as well.

I know this could probably be anything, but is there anything I can do?  I'm
still using that anti-fungal medicine, but it doesn't seem to be having an
effect.

Any suggestions would be appreciated.  Please mail them, as I'm not a
regular reader of this newsgroup.

Thanks in advance,

I'm currently running a 55 gallon African Cichlid tank and

My current filtration consists of a Fluval 303 and an AquaClear
300. Would this be enough filtration to handle 4-5 medium sized
fish and a couple anemones? Is a wet/dry an absolute necessity?
Could I just add another Fluval and a skimmer? How well do anemones
get along with RFUGF? Should I shitcan the Fluval and AquaClear
and get a wet/dry? I'm so confused. Please help.

It occurred within historical time in Latin, leading to doublets such as
flo:s/flo:r and hono:s/hono:r, which are examples of paradigmatic leveling:
Under pressure of animates with nominatives in -o:r, genitive -o:ris, the older
forms such as flo:s/flo:ris --> flo:r/flo:ris.  This occurred late enough after
the introduction of writing that we have examples of both.

There were no neuters in -o:r, so s-stems such as genus/generis <
*genos/genesos do not undergo similar paradigmatic leveling.
