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

So as the term cycle has got a bit of bad press of late I am suggesting the term IBC (Initial Bacteria Colonisation) what do ye think

Oh and I have a question of course.
I have been feeding my new tank for week and still no ammonia, are my plants eating it or do I just need to be patient for a while longer? Someone ate all the prawns I was going to use maybe I'll pick up some more.

Hi Q. It has got some bad press on here but I don't understand it myself. Call it nitrification, break in cycle or IbC, it amounts to the same thing...I believe it's much better for new fish keepers be aware of it than not be which spares new fish being dumped into an uncycled tank and exposed to lethal gill burning levels of ammonia and nitrites...

Apart from being not correct, it does go further than just a semantic difference.
I have seen, and many here have also seen, keepers tanks described as 'cycled' (ie in taking on-board incorrect information) yet the tank has clearly collapsed because the tank is not actually "cycled" or fully mature.
I do, however, like Q_Comets IBC terminology. Not only is it correctly addressing what is going on, it also highlights the fact that the "all clear" (so often given in the "cycled" false confidence) is not as "all clear".....iesomething is just starting (even if finished).

Anyway, the Prawn and the Plants (good film title there)......the prawn may have some ammonia within it from scratch, but the majority of the ammonia from the prawn would come from ammonification action of microbes (one of the sets of microbes within the "cycle").
Normally, the microbes in ammonification get going quite rapidly. But that is still no guarantee.
The process of converting nitrates to nitrites to ammonia (through nitrate reduction, nitrite reduction and ammonification) will also occur as part of the cycle but not usually in the initial period (because the concentration of nitrites and nitrates will be low)
Some plants may uptake ammonia directly.
Some bacteria will also assimilate ammonia and use it as a nitrogen source, they are also part of the cycle but I wouldn't count on them being in a new tank. But they could be if you happen to have them on the roots of plants or in soils.
Then we have the small part of the nitrogen cycle that converts ammonia to nitrites (nitrosofication) and nitrites to nitrates (nitrification).
The nitrosofication process can establish itself quite quickly within the water column but even more quickly on a surface. Normally, we would expect a few days to get a useful amount of nitrosofication working to cope with a limited stocking level, but there are many ways that the tank can be seeded (even bacteria on the roots of plants).
Ammonia can be converted into nitrogen gas directly in the aquarium (without going through the nitrite and nitrate production phases).....but, again, this is not likely to happen in a newly set up tank as it is major part of the mature tank but unlikely to exist to any useful extent in tanks under 9 months or a year old due to the incredibly slow growth of the anaerobic bacteria involved in this.
Of course, having a zero ammonia reading could also be due to a duff test kit. There is a lot of true SciFi on test kits

there's alot of "true sci-fi" on just about any chemical or biological product any company tries to sell!
hence such phrases as:
"the bubbles hold onto the dirt and grime!"
"age reducing plant sterols"
and my personal favourite... all that bollocks about a chopping board carrying more bacteria than a toilet seat. true, maybe, but i'm thinking the one that's more likely to keep you out of work for a few days if you licked it is the toilet seat!
I hasten to add, I'm not basing this on any personal experience

pro-arginine rubbed onto your hair?.....SciFi (eat the stuff in a balanced diet instead);
Health Food Shops?.....SciFi (I have yet to see a bag of spuds or fresh fruit in a health food shop);
Danone "calcium rich" rubbish?.....SciFi (if you then drive your kids to school, stuff them full of coca cola, and let them play computer games rather than getting some sun-rays).
Biochemistry produces the most cynical scientists?.......Science Fact. (I can get you proof).
Licking a toilet seat to test Myths?.........priceless. (leave that to the professionals with dodgy big 'tashes)

If I had money for an accelerator, I'd probably just build a Formula One race track and waste my time driving a F1 (no...not a first generation wild group of convict cichlids) around it. That would be more fun, and a lot more useful to society (says I).

By the time this thread has gone off topic and come back to the original subject, the tank should have cycled....whoops, I mean lapped.....ummmm....started the IBC, I mean.

So as for progress I think I will switch to nitrite tests in a few days

I dunno about "IBC". Makes me think of an irritable bowel.
Maybe that is what was up with unlucky IBS I should take him to dr herbs
