Tank cycling discussions

Recommended Posts

The more frequently that water changes are carried out the less difference there will be between the tap water and aquarium water. The aim is to establish a balanced system between the toxic wastes produced by the fish (ammonia and nitrite) and the bacteria helping to create the balance and there are a number of ways this can be achieved. The best way is the way that works best for you and done properly none of the ways need to be cruel to the fish.

Agreed, I have spent many hours in the LFS up here and I have heard for myself the advice given out. 99.9% of what I have heard is good, sound, unbiased advice. I have seen many many times people ignoring that advice and insisting on needing this and that. At the end of the day the shop assistant has no choice than to sell them what they ask for.

I have also read on this forum people saying that the LFS told them this and that yet I have been in the shop that very time and know very well that that was not what they were told.

But this thread is not for debating this but for discussion on cycling should anyone wish to do so.[/quote

I guess impatience would have a lot to do wit hit as well. When some one starts out and decide they want fish, they want them now and want as many as they can fit. they dont want to come home from the shop with a empty tank.

Yes maybe this discussion should also have its own topic. Feel free to cut it or delete it Mods and back to cycling. Cheers

I think some people who have not been involved in importing or breeding heaps of fish would not realise how much you can get away with and how tolerent fish can be (some species). When doing either of the aformentioned there is an economy of scale where people try to load their tanks to the maximum because the overheads are pretty much the same for 100 fish or 1000 fish. With experience these people would get away with what others would consider over the top. And by the way fish which have had their gills and or fins burned off with ammonia poisoning are not very saleable so this is to be avoided as are dead fish in Quarantine as this makes Maf get all excited.

Why sticky "water changes?"

I wonder then if these people who might lose 10% of their stock due to whatever practice they use might not mind so much because their profit margin is little affected. In contrast with the home keeper who will get upset at losing the same percentage but with say 10 fish.

And it can confuse people who look at the overstocked fish in the LFSs often not realizing that there is massive filtration and automatic water change occurring behind the scenes to allow this to happen safely.

When quarantining fish a 10% loss of fish would bring Maf in with a big sledge hammer and from a commercial point of view there is no profit in dead fish. It seems that you are having difficulty accepting that there are many ways to cycle an aquarium as there are many ways to breed and keep fish. I think people starting out there should be given these options so they can make the choice as to how they wish to carry these things out. Your reference to my grandfather only shows that you have missed the point. As I stated, neither of my grandfathers would have kept fish as they went through depressions and world wars and therefore would have been more interested in being able to keep themselves and their families alive and fed. My reference was to "grandfather" meaning a generation or two ago.

you need to quantify your statements as you make them

back on topic

you can cycle a tank using chemicals to provide food for your bacteria to establish

or you can use a few fish to do the same thing

you can add chemicals to lower your ammonia etc

or you can do a water change

the slower you do the water change the less chance of shocking the fish

Pretty much sums up every arguement / discussion on here, in 5 lines.

fishless cycle produces an indeterminable amount of bacteria

so how do you know how many fish to add to produce enough waste to match the amount of bacteria present in the tank

or is it just a case of bung a few in and hope you've got it right

if you don't match it up properly will you get a die off in your bacteria instigating another mini cycle

I guess it doesnt really matter if you dont add enough fish and some bacteria die out, enough bacteria will survive to match your bio load. You would get a spike if you had too bigger bio load. And surely if your tank is cycling 2-3 ppm ammonia in 12 hours that is a pretty massive bio load. Tests have certainly been done to measure the amount of ammonia produced and im sure people who cycle with fish and have experimented with how many fish they can add to start a cycle and tested their ammonia levels would have an idea on this.

Tests ive seen were basically based on inch of fish per gallon of water and ammonia produced. So many variables though like feeding etc.

End of the day- just like cycling with fish- it comes down to experience and no doubt alot of the info we get today is based on trial and error.

Some Pros with fish less cycling;

ammonia is cheaper than fish

you dont have to expose fish to ammonia,

no daily water changes etc to keep ammonia below harmful levels.

Can be quicker than cycling with fish as you can have optimal bacteria growing temps and PH levels that may not be suitable for some fish species.

Tank can be fully stocked immediately

Some Cons;

Clear/ pure ammonia can be hard to source,

Cycling with fish food, shrimp can be hard, slow to measure

You dont have fish in your tank immediately

Some breeders will tell you they cull heavily and some do but most in NZ seem to breed anything to anything and sell the results. I judge this on the number of goldfish sold that are rubbish. Black moor nymphs and oranda nymphs---all of that rubbish would be live food in Asia.
