Came home this evening to find the temp in my main community tank a
little
bit on the high side - this was the one that was the coolest in the
last
blast of heat that we had.

Did a water change and then noticed that the outlet of my filter
(Fluval 304
ext) was not throwing any water back in. We checked the inlet valve and
it
was reasonably clear however unless we manually pumped no water was
being
drawn out or put back in. We think that it might be the impeller as the
motor is working fine - no blockages coz we can pump manually. Anyway
it is
turned off so that the motor doesn't burn out.

To protect the fish I have put in a Fluval 4 internal (fully cycled -
it has
been hanging around in another tank for months after being this one
originally - so in action for at least 10 months).

We can't do anything about the external until some time tomorrow. So my
question is will any of the bacteria survive? or will I have to start
it
from scratch again? It is still full of tank water.

Thanks
Gill


I don't think it will survive. Perhaps remove the media, rinse the dead
bacteria & detritus out and float the media in the tank (if you need the
biological capacity). You should be able to see the impeller turning
with the filter opened up though.

Well I suppose that at least by having the Fluval 4 int hanging about it
isn't a total disaster (fingers and everything else crossed). I won't be
happy leaving that as the only filtration/pump for more than a day or
two....plus the load it has had before (shared with a Fluval 302) is nothing
compared with what there is in this tank....but I guess I have the bacteria
that is in the tank anyway....few more frequent water changes until all is
sorted....

I didn't really want to set up a new filter system two weeks before we go
away but I guess with my MTS at least I can use some medium out of the other
tanks to kick start (not the one I just took the internal from though)....

What is it about this hobby that you go through a couple of days of thinking
everything is sorted and happy and then something else jumps up and bites
you?????
