Recently my betta has started breathing heavy. I checked the water quality and the ph has jumped from 7.4 to 8.2. I'm not sure if I should do anything to bring the ph down or not because I heard it was better to leave it alone. I know nutrafin makes a betta water conditioner that contains almond leaves which lower the ph. Should i try using this, leave the ph alone, or some other option? My betta is in a 5 gallon tank with a sponge filter and heater. I do water changes every week and the ammonia is 0, nitrites are 0, and nitrites are 10-20. any advice would be much appreciated.
