Ph levels keeps decreasing

I have a VT Betta (Garp) for about 3 months in a 2.5 gal tank.
About 2 weeks ago, I had a sudden drop is ph level around 6.
I believe his tail was burned away about an inch, or intense fin rot, and I treated him.

His tail is growing back, but every time i check his ph level it is always decreasing for some reasons.

I do a 100% water change once a week, follow instructions on adding conditioners and Ammonia remover to make the ph level at 7.4~, soak decorations in hot water for 30 minutes, rinse the gravel 3 times in hot water, and replace filter cartridge. I always keep his temperature around 76~81 degrees.

After 2 days, Ph drops to 6.3~ and I add ph increase to make it around 7.4.

I never had this problem before until now.

Would there be something in the fish tank that is causing my ph level to keep decreasing?

What kind of testing product are you using, what kind of substrate and type of decorations in the tank, any live plants, if so, how many and species, name of additive used, type of filter and filter media....

Test your source water pH

Draw a clean glass of source water test pH then let this glass of water sit for 24h and test it again, test the tank-and compare all these numbers...and post...

In a 2.5gal tank-due to the number of needed water changes I would not add pH adjuster to start....I would limit the chemical additive to just one dechlorinator "Prime" all those additives are not needed and can make the fish toxic over time....you should be making twice weekly 50% on a 2.5gal filtered tank to maintain water quality and the Betta will adjust to your source water pH....

I am guessing I put too much chemicals into the tank, which probably lowered my pH level over time because after doing the 50% water changes and using only Prime, my tank is around 7.4 pH instead of 6.0

I'll see how the pH will behave after two weeks.

Thank you for the info Oldfishlady

@nuocam: did you purchase the minibow 2.5gal online or in the store? i'm wondering if its a good deal for me. i can find 5 gal glass tanks here for around $44CAD. is it possible to get the same model at lower prices at walmart or a pet shop? what quality of tank is the aqueon 2.5gal? how does aqueon compare to critter keeper in price and quality?

I purchased my minibow in stores at petsmart for about $30 USD (it was on sale). I don't know if walmart or a local pet shop would carry it, but I recommend calling them to find out.


Here's a link to my tank.
http://www.petsmart.com/product/inde...ductId=3611436

I can't tell you much about the quality since I have no problems with it so far, but the reviews on the link above might help.


Comparison to critter keeper, I don't know since I never knew about critter keeper.

Hope this helps. If this doesn't help, you can search in the forum and/or post a thread and i'm sure someone can help you.

goodluck

ty, im not sure which one is better for me to get. critter seems less expensive but then again its not much for amenities. aqueos is more expensive but it has some extras so im leaning more towards that one. it also doesnt look much like an aquarium from its simple design.

@NuocCam: Get a full testing kit and check the Alkalinity. It may be too low, causing obvious swings in water chemistry. If your Alkalinity is extremely low, then the CO2 that your fish is exhaling will lower the pH. Considering your tank is 3 months old already, most "tank processes" will eventually lower the pH over time. Also as OFL said, test your tap water as well...if the KH is also low in your tapwater, then that is probably the cause.

If it is indeed that the Alkalinity (KH) is too low, then you must purchase a buffer chemical, or just do more frequent water changes to prevent crashing.
