So last week my betta's ammonia level went up to 0.1-0.3 and being a new betta owner I sped to the pet store and asked how I could bring down the level. The guy gave me a small sack of rocks to put in the filter and I did it. I changed the water today and tested again and the ammonia is the same and now the pH is slightly more basic (from usual 7 to somewhere between 7-8). I know how to test the ammonia, but have no idea how to fix it. What is happening? What do I do?
He's a VT, don't know how old.
He's not acting any differently: it's more of a stop it before it does affect him emergency.
His tank is a 10 gal., with a filter, no plants.
Usual levels are:
I do a 50% water change every week.
I feed him everyday: 3 betta bites and 1 freeze dried bloodworm.
