Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

Anyway, duvets round tanks and stirofoam lids or stirofoam wrapped round the tank will be a serious benefit. Also as Ian said, I would definitely do a partial water change before hand to ensure filtration isnt as big an issue

For myself I have a small two-stroke generator which I bought from a good friend when he was leaving to emigrate to Canada (reminder to myself to get some petroil in the week - just in case). This will be merely for power to keep the filtration running = water takes a long time to heat up and also to lose temperature as well so my prime concern will be to keep the bacteria 'active'.
Quite a good investment is a battery-powered air pump, these will run for a good few hours on fresh batteries and can be used to save any air-driven filtration bacteria. Obviously if you have more than a couple of tanks this mightn't prove to be feasible, but worth considering nonetheless. Let's all just hope that good sense prevails.
I'm waiting to hear - if they do go ahead - more details of power cuts, especially duration and timing.
But it really is in all our interests to at least think about what may happen and to make (even if only mentally) contingency plans.
Out here in the middle of nowhere power outages are doubly harmful, I rely upon it for my water supply (from the well) too.
It's funny, really, how we are so blase about these things - but in all honesty life out here grounds to a halt every time the lightning strikes a power line, or - when it's windy - a tree is blown onto cables and damages them and - as happened here recently - a farmer broke an underground cable when opening a new ditch with his JCB! Like our cars, we take it for granted and only really notice when it/they aren't working!

The shed is warm even now while it's cold
But that's down to two things
1,there's a rad in there and
2,the warm humid air from the heat of the tanks
Now if we lose power,I have nether
And that leaves me with two options
Buy a generator(not feasible with the Santa fella on the way)
Or bring all my stock to someone who has a generator
Is there any way of getting a petition together,
Getting everyone here to sign it and send it on to the powers that be?
Based on the fact that there's going to be a massive strain on the fish keeping
Community and there's a good chance that people like myself are going to lose out on a lot of hard work!

Maybe someone here understands these things better and can get something organised?

I suppose having experienced pretty hefty power-cuts with fish tanks in the 70s in the UK during winter does help give a few ideas of what to expect.

Would a canister of compressed oxygen do also?

Good thinking batman

I probably wouldn't recommend the compressed oxygen on safety grounds......and the oxygen saturation in the water afterwarsd may be just too much for the fish.

there is no way they will strike .. its all hot air
Agreed, I cannot see this happening in a modern society and that's probably why there has not been more interest in the post.
The thread is however a very good reminder to get prepared, there could be a power cut from natural causes anytime. Like John pointed out it might be even more relevant out in the countryside.
I have wanted to get a backup plan for a long time now anyway, either a generator or plenty of those battery driver air pumps, can't decide. I'm not too worried about the heat loss as I can't see a power cut last that long.

from what I've heard from several sources, sponge filters seem to last especially well in the event of a powercut; unlike, for example, an external filter

Good point, +1 for the generator then.

Actually they even last pretty well in the absence of any air flow at all. Unlike an external filter, where once the power stops your bacterial colony is cut off totally from its food supply (and so can only last a few hours), a sponge filter is still sitting in a larger body of water and at least has some access to sustenance.
Sponge filters rule

Mature does not mean "old"......it's a bit like vintage port: it is vintage the day it is picked; it is only a good wine that get better with age; a poor wine get worse with age.

Recently set-up tanks (eg ones under a year old or ones not set-up fully), though, are most at risk from failed filtration during a power-cut.

I think the 13/14th Dec. is the earliest they can strike.
For heat you can wrap the tank as suggested. But you can also get heat packs in camping shops. Place them in side a deflated and tied fish bag and put at the bottom of the tank.
To keep filter bacteria alive from internal or external filters get a large lunch box. Drill some 5mm holes in the sides and drill some holes across the top.
Place the filter media in side and place some air line in to one of the 5mm hole in the side.
Stand the box up right in the tank. Connect the air line to a battery air pump (available at some LFS).
This will keep some of the filter alive and add oxygen to the tank.

LJ,
As I understand it (and I'm perfectly open to being corrected if I'm wrong) your last observation is missing the point somewhat.
In our filtration systems there are two types of bacteria, aerobic and anaerobic - one of which needs oxygen and one which doesn't (don't ask me which is which though, although I do think it's the former).
So, without the oxygen the one which depends upon it will quickly die off and this will break the whole chain.
Perhaps IGM could tell us more when he has the time.

I get what you're saying. I'm not saying they don't need oxygen; but a sponge sitting directly in a tank will survive longer than an external, which is more or less starved of oxygen/nourishment from the moment the power fails. And it then pumps all that toxic water back into the tank once the power comes back. But if the tank becomes depleted of O2, then yeah, you're screwed... and not in a good way!

If you have obligate (strict) aerobic bacteria then they demand oxygen; obligate anearobes are gonna die in the presence of oxygen (well..usually), but there are facultative anaerobic bacteria that will live with or without oxtgenb (I won't go into the full definitions here though).
In the fish tank you will obligate aerobes, obligate anaerobes, facultative anaerobes all in various amounts and activities and doing all sorts of different things.
It is not just the question of a process stopping but that a process may start to reverse itself under anoxic conditions that is of concern...eg reduction of nitrates to nitrites and reduction of nitrites to form ammonia !!!
Denitrifying bacteria are actually aerobic bacteria living under anaerobic (anoxic) conditions.....they are not anaerobic.
A very important group of bacteria are the anaerobic oxidising bacteria that oxidise ammonia to form nitrogen gas.....but these are slow to grow and are unlikely to exist in immature tanks.
