View Full Version : How long will my bacteria live if I switch off the filter ?

Hello,

I have a new filter maturing on my old tank. When I come to move it to
my new tank, I will (obviously) need to switch it off and move it.
Ideally I would like a bit of time before switching it back on as I need
to work some plumbing and other bits around it before I fill the tank
with water.

So, how long will the bacteria survive ? It is an external filter, so
when switched off it stays full of water.

TIA

Time-wise it's hard to tell how long the bacteria can survive. Maybe you can
fill up a bucket with old water and run the intake and the filter output in
it and leave it on. Just a suggestion. Hope it helps.

That's an idea. Thanx.

That might work for a day or two but eventually the bacteria will run out of
"food" and die.

if circulation is provided, couldn't bacteria last longer? with or without
air, not sure....

People can last a long time without food. Not sure for bacteria. I
wouldn't take a chance personally cause its pretty easy to clean out the
filter.

So throw in a pinch of flake food everyday?

I think that when bacteria run out of food, they go dormant, but when
they run out of oxygen, they die.

If they remain dormant too long, then they die, but how long is too long
will certainly vary by species, and I don't know how long it is for
nitrifying bacteria.

Keeping water circulation is certainly a good idea. I doubt the bacteria
need a very uniform supply of food, at least not any more uniform than
the fish get. A day without food might make no appreciable difference.

Thanx for the advice (and to everyone else too). I have decided that the
extra few bob[1] it's worth buying a few extra bits of fittings and
plumbing the new tank in completely before moving the filter. I was
hoping to use the old ones, but due to the delays that this would cause,
the filter would need to be unplugged for a few days at the least,
possibly longer. I'll just end up with some spare bits. On the cost of
the tank, etc it's not much.

Thanx

Shillings were called bob !!
