ok ive read numerous articles on cycling the fish tank and i just dont seem to be able to get my head round it.
i just dont understand the whole process. i must be thick or something, it all just seems really confusing. is it possible to do a fish cycle, or is that a bad way of doing it.

are there any good books on the market that u guys recommend as being the best all rounder that have all the info so i have it all in one place.

arghhh so confusedddddd.....
 
hi,
dont worry i was the same until i joined tff,
you can cycle with fish or without, ammonia is the key to start with, this is needed to start off the cycle. ammonia from either the fish themselfs or without fish from a chemist, have a look at the pinned topic in the beginners section, hth donna :)
 
cycleing is easy....

you need to add ammonia

bacteria a eat ammonia and turn it into nitrite..

nitrite then gets eaten and turned into nitrate

you get rid of the nitrate with wate4r changes....

in a fishless cycle you add ammonia to 4-5 ppm (roughly)

you test it every day, when you see the ammonia go down that means that the bacteria is growing in the filter

as the ammonis hits 1 or less add more ammonia to take it back up to 5 ppm

when your adding ammonia every day you do a big water change (80%) and you can add fish within 12 hours of the watter change (or the bacteria start to die off)

its alot less work than cycleing with fish as when you do it with fish you have to do water changes every day or other day ect depending what the readings are. (ALOT of work)
 
So- cycling is the process of the tank growing a colony of bacteria large enough to deal with all your fish's waste. These bacteria need to be of two kinds: the ones that transfrom ammonia (excreted by your fish) into nitrites, and the ones that transform the nitrites into nitrates. The bacteria multiply when they are fed, i.e. when you either add fish to a new tank or start adding ammonia (fishless cycle).
In other words, a cycle will happen in your tank if you are going to add fish- it's not something you can opt out of. The choice is how stressful it's going to be for your fish.
The dangerous period is while the bacteria are not yet abundant enough to deal with all your fish's waste: during the first part of the cycle-with-fish (before the ammonia-eating bacteria have multiplied), any fish in the tank will be suffering from exposure to ammonia; during the second half (when ammonia-eating bacteria are producing nitrites, but there are not enough nitrite-eating bacteria), they will be at risk from nitrite-poisoning.
You can allievate the sufferings of the fish by frequent water changes, by only adding a very few fish at the start of the cycle and by choosing specially hardy fish.
Or you can eliminate the suffering altogether by letting the bacteria multiply on a source of non-fishy ammonia (usually liquid household ammonia from a bottle) and only adding the fish when there is a sufficient colony of bacteria in the tank. This means a period of waiting- anything from 10 days to a month or over- looking at an empty tank and testing the water every day. (Note that you are going to need testing if you cycle with fish as well). But your fish will be less at risk. And you can spend this period in researching the species.
Note that either form of cycling can be made a lot easier and quicker if you are able to get hold of some mature filter media. There is a list on this forum (pinned topic) of members who are happy to share their filter media with anyone setting up a new tank- check out if there is anyone near you who could help.

Take a look at this thread http://www.fishforums.net/index.php?showtopic=160806 It might help.
 
ok... still confused. sorry guys, i must be really thick.

ive had my tank set up since friday, with the filter set up and filled up with normal tap water. whats the next step. i think i need one of them step by step instruction things, like 1. get amonia 2. get test kit 3. get thermometer 4. put in amonia etc. lol.

Ok

1 Get water conditioner / de-chlorinator - add to your water. (Chlorine & chloramines will kill your beneficial bacteria)
2 Get ammonia - try boots if you're in the UK - Household ammonia
3 Get test kit - liquid master test kit
4 Get thermometer - get water up to about 25-27 degreesC.
5 Try to get some used filter media to help introduce bacteria to your tank and/or second best add 2 or 3 hardy live plants but leave them in their pots with the rockwool wrapped around their roots - echinodorus bleheri is a good choice.
6 Add ammonia a bit at a time until you get a reading of 4-5ppm on your test kit - make a note of how much ammonia is needed. Its best to do this using a small syringe to make measuring easier in the next weeks.
7 Test water everyday for ammonia (can skip the odd day early on).
8 When ammonia gets down to about 1ppm (will probably take at least 4-5 days - maybe longer) add more ammonia to get level to 4-5ppm - do this each time your ammonia level drops to about 1ppm.
9 When tha ammonia level starts dropping between adding more, start testing your nitrite levels. They will steadily climb until they are off the chart. Dont panic - just keep testing the ammonia as well and adding more as before.
10 Keep testing ammonia and nitrite daily.
11 Eventually you will find that your nitrite levels start to fall too - this will take a good bit longer - probably twice as long as it did for your ammonia. When this happens test for your nitrate - it should be high!
12 When your tank can process 4-5ppm ammonia into 0ppm ammonia and 0ppm nitrite in less than 12 hours your tank is fully cycled.
13 Turn your temperature down to the required temperature for your fish.
14 Keep adding ammonia for a day or so just to make sure the temperature change hasn't caused a bit of a die off in your bacteria - it should all be fine.
15 Do a big water change - about 80% of your water. Make sure that you match your water temperature fairly closely (by hand is fine) and add your de-chlorinator to the water in the buckets before adding to the tank.
16 Go to fish shop and buy fish - acclimatise correctly and add to your tank.
17 Sit back and enjoy - you have just become a fish keeper. Now the whole thing starts in earnest.

The cycling process can be over in a week or two, most seem to take about 3-4 weeks but some may take 9 or more weeks. Stay patient - take your time to read loads on the forum and research your fish - thats the fun part.
 
thanks scoobadoo, that really helped.
im sorry im such a pain, must be really annoying for everyone to keep repeating things all the time.

i was really looking forward to getting some fish on friday from advice from pets at home, but after reading this and now understanding it better, i will go for the fishless cycle.
