Samus the goldfish will be in the 40 soon, I just don't want to stress him out. I love the little guy and would rather keep him in the 5 gal now than the uncycled 40.
I agree with you Squeakfish, The most important thing you mentioned is that you have time.... I believe too many folks loose their patience when it comes to cycling a tank..(or have livestock on hand and no place for them) notice all the replies concerning speeding up this process...why risk the health of your livestock or put "expendable" livestock in that environment?? when you can do a fish less cycle and spare the fish any unwarranted stress. I believe the more people hear and understand the benefits of a fish less cycle the more folks would recommend this over any other....
That being said, I also believe that there are methods posted here that will help speed this process along, 1, Seeding from an already cycled filter media is by far the best... 2, using some substrate from an established tank is another (both methods used in combination would help greatly) leaving plants in the pots that you purchased them from (most come in "rock wool" media) most likely are already teaming with N-bacteria.
Here is what I would consider methods that should be avoided...
1. Don't rely on off the shelf "quick fix" cycle solutions (don't waste your $$).
2. Obtain a liquid quality H20 test kit... API or such within your $$ range. Stay away from test strips.
3. If doing a fish less cycle don't test for anything other than NH4 (ammonia) Your target base NH4 level is 4-5 pmm... your other tests mean nothing at this point. only begin to test for N02(Nitrites) after your NH4 drops back from 4-5 ppms to .25ppms or so within a 12 hr period after adding your NH4. (this means that your N-bacteria are converting NH4 to N02). Don't freak... your N02 levels will begin to go off the chart!! remember that your still adding NH4 at 1/2 dose, your new NH4 target is now 2-3 pmm.
4. Don't perform any H20 changes during this process...Why? remember you have no livestock suffering within the system... You may have to add H20 for evaperation... let it stand for 24 hrs prior to adding it to the tank. don't add any declorinators to it, most will bind ammonia as well... no need.
5. Don't rely solely on plant mass... this directly contradicts what you are trying to achive... a well established bio filter capable of ingesting the NH4 from your livestock.... If you where to add plant mass prematurely this would directly compete with the n-bacteria for the available NH4. giving one a false sense that the N-bacteria are establishing/multiplying themselves. remember... your developing a bio filtration system not feeding plants.
All that said, cycling a tank takes time don't loose your Patience in this very important step. Most folks cant understand why they keep loosing livestock even after they have "cycled" their tanks. I contend that some of the remedies to speed this process actually hurts the Bio filtration system or at least weakens its capacity to handle a larger bio load from increased livestock once released into the system. Build your bio filtration large enough from the beginning before you add your livestock and you will be well on your way at being successful in this great hobby.
