If there's no filter, there's nothing to cycle. So no.

You can't cycle an unfiltered tank, but what you do need to do (if there are fish/critters in the tank) is daily 100% water changes to prevent ammonia levels building up.

just buy a filter other wise your levels will fluctuate so much it will cause your fish great stress and will not live very long besides filter and now realy cheap you could buy 1 of ebay for a tenner i bet thats if u got fish.
What u planning on putting in this tank, and i'm baffled you you don't have a filter

I always thought un-filtered tanks would eventually cycle?
With your AOB and NOB building up on most surfaces in particular the substrate, obviously as long as there is enough oxygen in the water
Either way, i'd agree adding a cheapo filter would be alot quicker and easier.

may i ask y 100% daily water change if he has no filter the maximum should really be 20% daily and if u are doing this amount of water changes daily surly getting a filter should make a lot more sense

With bettas you're probably better off with no filter and frequent water changes. Bettas produce very little waste, they're more likely to be stressed by the current from a filter than any ammonia. Even after almost two weeks with no water change on one of my betta tanks, I couldn't detect any ammonia.

ooooops my bad did not see that i just read 5 gals does it need cycling i stand corrected

If you can get a cheap enough filter the it would be worth using one. You can adjust the flow on most of them so that little or no current is created and your Betta will be fine.
I had Fluval 1+ filters on my old 5G tanks and just placed an ornament in front of the nozzle.

yes you will need to cycle the tank no matter what. But you may not notice it. There will always be poop if there is a fish and where is the poop gonna go? Just because there is no filter or a small tank doesnt mean the poop wont become ammonia.

Fish produce poop every day, if you only doing 20% water change every day in an unfiltered/uncycled tank then you are only removing 20% of the ammonia from the tank.

When i had my betta, he was fine with a little Fluval 1 Plus filter in its tank, seemed to show no sign of discomfort or stress with having the filter in its 5gal tank. Was very easy to cycle too, since i just put the little filter in one of my established tanks for about a week to cycle (using the Cloning method of cycling) and then just moved it over to the 5gal on the day i got the betta.

Did the betta tank which you did no water change on for 2 weeks happen to have some thriving plants in it? What test kit did you use for testing the water with?
