finrot - water changes not helping

Long story short, I was originally keeping a betta in a 1 gallon bowl and doing 1 25% and 1 full water changes a week for a couple of months with no issues. I bought a 2.5 gal but was lazy about cycling it but I didn't want to place the betta in a uncycled tank. But being only 1 fish in the tank I didn't think it would be that big of an issue plus I can begin the cycle with the betta.

Since my betta has been living in the 2.5 gallon tank (the last few months) it started to develop finrot. I've searched for solutions on the forum and since the finrot was not bad I decided to not mess around with medicines and just do water changes.

I change 1 gallon of water from the tank every 2 days but sometimes 3 if I get lazy. The fins of my betta is still rotting away slowly. Despite the frequent water changes, do I really have to result to medicine? And if so what kind?


The tank used to be 77 degrees but I raised it to 79 degrees to help with the healing. The tank is also filtered with a red sea nano filter rated for a 3-5 gallon tank I believe. I clean the filter media in old fish water once a month. No plants yet and the substrate is a mixture of onyx black sand and black sand eco-complete. I'm not too sure on the parameters of the water. But I do so many frequent water changes, I didn't think there would be any massive build up of ammonia, nitrite, nitrate, etc.

I'm not too sure how to read these but my water parameters seem to be fine to me.

Ammonia


Nitrite


Nitrate


Suggestions anyone?

How long after a wc did you test?

Zero nitrate means this tank isn't cycled. Even with the frequent water changes there will still be a build up of ammonia or nitrite at some point as there is not enough bacteria to process your bioload completely.

Bettas like water closer to 80 degrees anyways, so raising the temp shouldn't be an issue. I've never had problems with bacteria not colonizing at similar temps.

I did the water change this morning around 11am-12pm. I tested the water right before my post so I'd say 615-630pm.

I understand the the tank might or might not be cycled. But how much ammonia/nitrite can possibly build up with 1 fish in the tank. It's not like I have a community tank here with multiple fishes defecating continuously... I do appreciate you're input but how much can the ammonia/nitrite be over 2-3 days from 1 fish, seriously. It doesn't make sense. The frequent water changes would remove all the 'build up'.

Well I only increased the water changes to fix my bettas finrot but it doesn't seem to be helping? It actually got worst from this morning. =|

But I will continue testing daily and keep this thread updated. Thanks.

UPDATE:

The parameters seem to be the same as yesterday. I did the water test between 415-430pm which is roughly 10 hours from my first test.

Depending on how bad the rot is getting, you might consider treating with maracyn and/or maracyn 2.

Well I would say at least 50% of his original fins have disappeared since being placed in the 2.5 gallon. It was a very slow and sad process to watch. =( Would you suggest treating with meds at this point?

Day 3 UPDATE:

Water testing 26 hours after second water test. The water parameters are pretty much still the same 56 hours after last water change.
