I'm looking into cycling a 1 gallon MiniBow with a filter. I know I'm going to get scolded for even asking this question, but I do have cycling experience, just not with bettas. A fish breeder told me that you can basically cycle any size tank if done properly. I would be monitoring ammonia and nitrate levels, of course. I was thinking a 50% water change once a week for week 1 and 2 of the cycle. Then I would do about 1/3 for week 3. Week four and beyond would be 25% water changes. I've done this exact cycle method on a 30 and 55 gallon Angelfish tank. Any opinions would be greatly appreciated. Please, no scolding :P
Edit: Read around a bit on the forum and other sources, will not be cycling the 1 gallon. Don't want to even put my fish in any danger. Will probably upgrade to 5 Gallon sooner or later and will cycle that. Was also told by the breeder that 50% water changes every 5 days in filtered 1 gallon is sufficient. Gonna test this out with the kit to see if it's safe.
You could not cycle it with the bacteria normally used to cycle a tank without plants. There is just not enough surface space for enough bacteria to break down as much waste as a betta would produce. They are just too dirty/big of fish.
However, with enough live plants there is some possibility of it working. Again, not sure if there is enough room. 1 gal is pretty darn small. I am trying to cycle a 2 gallon tank with plants right now. My suggestion for you if you want to try to cycle a 1 gallon is to not put a fish in the tank for at least a month. Give the plants plenty of time to establish, root, etc. Add your own ammonia of course, preferably with fish food because that has some nutrients as well compared to using just pure ammonia. Only one change a week for the first week of cycling would be deadly for any fish in the tank anyways. In my 2 gallon I can't go more than 2 days without changing the water.
Is your two gallon filtered? Why is it that you must change water every two days? Tomorrow I'm going to start an evaluation on how often I have to change the water in my 1 gallon provided the current conditions. I purchased a 5-1 test kit and after the water change I'll monitor ammonia, nitrate, and nitrate levels. Whatever day significant values start to show up, that's how often I'll change the water. Unnecessary frequent changes can't be good for any fishes well-being.
No filter, just a ton of plants (and a heater of course). I have been testing the ammonia daily. There is actually a topic on it in the Habitat section titled "2 Gallon Planted Experiment". I am only doing about a 1/3 change every day. They are easy to do. The plants just haven't had a chance to establish themselves yet. A fish-in cycle means you have to do a lot more water changes because you have to protect the fish. And it is an experiment....
With your tank, you only need to worry about the ammonia. Since you won't be able to get a cycle going. The nitrites and nitrates shouldn't happen at all.
Ahh, I see. Well good luck, hopefully all goes well. I have absolutely no experience with live plants, although I hear they are very beneficial. You're correct on that too, nitrates and nitrites shouldn't happen. Hopefully with conservative feeding, about 4 pellets per day, the ammonia won't show up for about 4-5 days. I'm hoping to be able to do 50% changes about every 4-5 days. I'll use an ammonia remover in addition to the dechlorinator. Once I figure everything out, I'll go from there.
