Pet Forum / Aquaria / Freshwater / November 2004

I'm the newbie with the divided 10 gallon holding two bettas.
When I was trying to find what the bettas liked to eat (Hikari) I added
two ramshorn snails, one for each side.  They were happily eating the
detritus, the sunken food, and the occasional leaf (the tank is heavily

I'm grappling with green water, and I'm going to keep tabs on it in
this thread.  Jump in with ideas, suggestions, and
what-are-you-thinking type stuff.
BACKGROUND:

I have a couple of Eheim Professionel 2s that have been using the same
Substrat media since the filters were purchased (one two years ago, one
about a year ago).  From what I've read, it seems like this media was
designed to be changed on a regular basis.  Why?  Does it lose ...

I've just setup a new aquarium (29 gl, flourite and a few plants, 55W
CF).  My water tests look a little wierd: the carbonate hardness is 0,
while total hardness is 120 with pH 6.8 or 7 (I can't decide which
color fits better).  So, I assume, that the only hardness I have is

I'm a long-time aquarist who's owned a dozen or more aquariums with most
common freshwater creatures at one time or another.  I've generally enjoyed
great success with all the fish that I've owned, from Arrowanas to Zebra
Danios!  I got out of the hobby over a decade ago, but got ...

We have a 30 gallon tropical freshwater tank.
Our one danio keeps chasing the other danio relentlessly.
Is this something we should be concerned about?  Should we separate them?
Thanks.

I have what appears to be velvet in my 30 gallon aquarium.  The fish look
like they are dusted with rust and have a reddish-brown sheen when I shine a
flashlight on them.  Water parameters are fine and I believe it came from a
fish I recently bought from the pet store.

Hello,
Our kids have enjoyed freshwater aquariums for several years in Ohio.
However, we have now moved to the central coast of California (halfway
between LA and SF).  The municipal tap water here is very hard,

Hello,   To give me something to do while the fish are swimming I started a web
site.  I tend to get very into (obsessed?) with my hobbies and this time around
of fish keeping is no difference.  I've read many valuable pages ...

All,
Can anyone advise.  I have a new tank set up, with 10 neons, 2 platies, 2
barbs and a gourami.  Although I haven't kept fish for years I used to and
was good at it.

I had an algae problem and bought an SAE.  About the next day all the algae
was gone.  About a month after buying the fish I find his carcass on the
gravel, but still no algae in the tank.  Now, about a week later I see algae
growing again.

My light keeps going on and off by itself. It'll stay on for 1/2 hour or so
and next thing I know, it's off.
The bulb is tight!
What's up? Is this a sign that it'll blow soon or am I missing something?

Does anyone know whether ROWAphos, a phosphate remover, also removes
whitespot medication like Protozin? I can find no information anywhere
about this. I'm about to phone Waterlife for futher information.

My white fantail (about an inch long) has developed a sort of greyish
crescent around her eyes. Water parameters are perfect (0, 0, <10). She
doesn't show any behavioral differences. Anyone have any ideas?
Thanks!
