I’ve had my betta for awhile and have been trying to fix my tank water situation. I’ve been testing the water regularly and no matter what I do the pH levels have been below 7.0 and my ammonia levels have been around 2.0 to 4.0. I have done regular water changes every week, I started to do 50% water changes but when that wasn’t fixing the situation I did 75% water changes. It’s a 5.5 gallon tank and I use API Stress coat, API Quick start, API ammo lock, and API proper pH 7.0 every water change except I use the API proper pH 7.0 and API ammo lock more often cause I thought they would help remedy my situation if I use them more. Please help me!
