Water circulation to prevent stagnation?

[nut]

Hi all

I have a tank with two small dempseys in it, with two filters - a small
external cannister and an internal powerhead filter.

When the water is filled to the top neither filter outputs produce any air
bubbles in the water, and only a small current... enough to push debris
around the tank, with a ripple on the surface.

Is this enough to keep the water from stagnating?

TIA

Yes! You do realize how large and aggressive these fish get I hope.

You should be fine for some time with the setup. Jack Dempseys are
pretty neat fish IMHO. Depending on tank size you should be fine with
the setup........They will outgrow a 10 gal tank but it will take a
bit of time......just something to bbe aware of.

Hi ya Nut.
You don't need bubbles in the tank to oxygenate the water. The
turbulance at the surface from the filters is where the exchange is
being made.
Now it would be a problem if the surface was still, then yes..it would
stagnate.

Keep up with weekly water changes as well.
Your Dempseys won't be small for too long. = )

Yes. Moving water wont stagnate.

Hi nut,

You don't say what the size the tank is but I hope that it is large
enough to accomodate them as the JDs grow - otherwise you are in for an
upgrade ;-). Apart from Angels I don't have any SA cichlids at the
moment but do have Africans - from what I've read and my experience with
the Mbuna these fish are pretty messy so over-filtering is a good idea
IMHO - along with plenty of regular water changes and gravel vacs...

Is there anything that makes you think that the water is stagnating? For
example an oily film on the surface or the water not smelling very
nice.....If not then your current set up is pretty much OK - and a
configuration that I use on a lot of my tanks - ie. one internal/one
external. I only ever add bubbles if the temperature in the tanks rises
too high in the summer - doesn't happen often in the UK......Having done
a quick google on JD's it appears that their natural habit is slow
moving water so you probably don't want to have them living in a torrent
from your filter outlets.....If you need to break up any residue from
the surface of the water try repositioning one of the filter outlets
upwards.....

Thanks for your reply Gill - and to the others who have offered their
advice.

I didn't think the water was stagnating, i was just concerned that, unless
it's getting enough oxygen & disturbance, it might... but i've since stuck a
bit of air hose on the powerhead so there's now some air bubbles getting
into the water.

The JDs are 4-5 months old... we're not 100% sure of their sex, but the
Alpha is now twice the size of the other (who, until recently, remained
hidded behind the filter) so we've called him Jack and the little one Jill.

Jack is now about 2" long, Jill is about 1".

They have their own 3 foot tank - just sand substrate & a 12" piece of
bogwood - which should do them for a year or two until they outgrow it.

In the past week or so they've started playing together and seem to be
getting on a lot better... Jack rarely chases her around the tank now and
has begun digging the sand up.

We've just picked up some live shrimp so they - and the convicts - are in
for a treat tonight... it's usually quite hard to find locally so they don't
get it much.

=====================
The *frozen* shrimp and other goodies are much easier to find here in the
USA. The fish seem to love them as much as the fresh live foods. You may
want to ask around and see which shops carry the frozen variety where you
live.

You are right that you may need to upgrade - but when do any of us fish
fanatics ever, ever complain about getting another tank ;-)

Your luck might be in - maybe you have got yourself a pair.....

Not sure where you are in the UK but I find my local Maidenhead Aquatics
carry both the frozen and live foods - with the live there is always the
possibility of introducing disease but all the frozen stuff I've bought
is zapped enough to make sure this isn't a problem - I buy the "Dutch
Select" brand.....You could always consider hatching your own shrimp of
course.....I've not tried it myself but am sorely tempted to set up a
brine shrimpery for my marine and freshwater fish.....

Duh..dumbass how are youy. frozen is not the same as live you babbling
idiot. Big difference in feedoimg gut loaded live shrimp to fish than
feeding anemic frozen crap...you dumbassed moron. Some muppets are
best if they learned to keep their pie hole shut and their ears open
and they may just learn something instead of popping off and thinking
they know everyitnng like you do carol.

snip a bumnch of inane crap of carol gulleys..

If you have a chance feed those little shrimp up with some spirulina
etc.......its easy to see when their guts are full, then drop em in
the tank with the predators. That way the big boys get a good load of
spirulina and other good stuff as well.......Most frozen stuff is
starved critters and nothing beats actual live food.

I keep a few guppys or platys around and often feed their fry to my
meat eaters......

[Tristin]

Hatching out brine shrimp gets old fast., I did it for about a month
or two, and its much easier overall to by eggs that have had the
shells removed and feed them the eggs...Its just as nutriious and much
easier.

I do however have a neat little device I made that I put a dash of
brine shrimp eggs in, fill with water form the SW tank, cap it and
place it in the sand bed. 18-24 hours later out swims the little brine
shrimps only to get gobbled up by the fish. No messing aorund and its
easy to make. I bet it owuld probbaly work ina freshwater setup as
well since sal****er is heavier, I do not think sal****er would
infiltrate the closed cylinder, and the salt water in the cylinder
device would be sufficieint to allow hatching of eggs. Heck the little
hatcheries they sell often use fresh water resivoir for them to swim
into.....but in this case they would merely swim right into the tank
with the fish and become snack food.........I know there is lots
odebate in feeding live foods over frozen, and the thing is how do you
really now if the frozen stuff has been zapped or just fash
frozen......I have fed live when I can for years and have never had a
problem, and that even includes harvesting of midge fly larvae,
mosquito larvae, may fly larvae and daphne etc .........I get tons of
blood worms and they scarf them up.

Maidenhead are the best... that's where we got our JDs from.

The more surface ripple the better
bubbles are not important.
turn the powerhead on it's side maybe so the surface is very disturbed.
I really don't use many airstones at all,
yep I have lots air powered filters
but they break the water surface enough to oxygenate.
Other wise i just play with the filter returns to get optimum surface
agitation.

Oh how I hate those little 'venturi' bits of hose for powerheads.
I wait until I have gathered a few dozen,
then pile them up and set them on fire.
I find dancing around the flames makes up for all the time I put up with
their non-stop horrible gargling.
Oh and many of me fish don't like the way microbubbles stick to them.
Each to their own.... but I think satan put them on earth as payback for
getting stuck with the bottem bunk meself.

I do not think the water is stagnant, I'm just worried that unless it get enough oxygen and interference, may be, but since I insist on a duct power head bits on some of the bubble more so now into the water.
