So, a little background. I'm on my third Betta in about 6 weeks. I'm really trying to do everything right. My water is very hard. It's registering 180 on the 5 in 1 Api test strip. My last water change, I used about $50 worth of Betta water hoping it would come down. I also read that an Indian Almond Leaf would help, so I added one 2 days ago. Just tested and I have zero nitrates and zero ammonia, but 7.5ph and 180 hardness. Any suggestions. I cannot lose another beautiful fish.
