Morning all,
About 6 months ago I was given a 4 foot community tank among it's
occupants were a few adult Bristenose cats and lots of young ones about
1/2 inch long, the long and short of it is that the adults have

Well, it's perhaps beginning to happen- the "worst case scenario" that
Steve referred to.  In our new (one week) 25 gallon tank with almost 40
small fish, I've just measured what I assume is the nitrite spike.
Ammonia levels have dropped to almost zero, and the nitrite level is

I was wondering about those Coolers used on PCs and small fridges we
see on sale in the shops.
These use a large semiconductor diode called a Peltier Device
(basically a large slab of silicon).

And we thought WE have trouble with predators and fish outgrowing tanks...
"MONTEREY, Calif. (Reuters) - A great white shark in captivity for a

Im a bit confused by the formulas on the web on how to calculate the volume
of a round kids pool....here are some of the formulas with the answers that
i have
Diameter x Diameter x Average Depth x 780 = Total Litres (216L)

I'm new to this stuff and have a new 70l tank with three platties.
One of them (bigger than the other two) stays at the top of the tank -
at 45 degrees - in the corner by the pump/filter - and just does not
move. It seems to be hiding from the other two, who seem to be quite

Hello everyone...
6 days ago I setup my 25G tank with plants and 5 neon tetras. It was
2nd hand setup I had bought and had been empty for 3 weeks. The pum
that came with it was a Eheim Pro II 2026. I only changed the whit

Oooo, I forgot to mention that when I was looking at them on Monda
morning, I saw one up close and saw something kinda fuzzy on the sides
My first thought was, "Oh, no! I've got fungus!" Then I noticed the fr
being completely still, but the fuzz was moving. And as this tank ha

I was putting a new sword plant in my angel tank and also took the
opportunity to prune a bit.  I was plucking old leaves and stacking the
wood a bit different, when I found a sword leaf with some snail eggs on
it.  I though, "that's weird, I've never seen any snails in this tank

I have a tank 6 weeks old and recently these rusty spots showed up on
plant's leaves, rocks and glass

FA = Free Ammonia, TA = Total Ammonia
My humble attempt at understanding their relationship:
(am I even close?)
FA = 0 for pH < 7, (Free Ammonia can't exist under ph 7 ?)

Hey Everyone,
I cant seem to find any websites that are strickly freshwater tanks. I see
reefcentrail is very nice and has tanks of the month, are there any
freshwater sites that have tanks of the month etc...

Hi, group:
My wife and I started up our first aquarium on the weekend, with perhaps a
few too many fish (about 38 small fish in a 25-gallon tank) but so far,
everything seems to be going fine.  Ammonia, pH and nitrite tests all come

I setup a new 80l (20G) freshwater tank 3 days ago. The shipwrec
ornament that was put in has a wooden mast. The wooden mast has gree
fur like algae growing around it already, approx. 6mm (1/4") all aroun
the wood.

My ammonia and nitrites test out at zero, so my bio-wheel biological filter
seems to be working well.  I'd like to figure out how often to perform
partial water replacements based on the nitrate levels.  At what level of
nitrate should I do a water change, and what level should I ...
