so, I finally had my water tested last night, the tests came back.... ammonia 10 ppm, nitrite 10ppm, nitrate 20 ppm, and ph 9.0+(she said it's normal ph for this area????) any natural ways I can lower ph??? ammonia and nitrite make sense, since I just combined my 2 tanks after the fireworks settled down a couple of days ago. I also had talked to my dad, he used to have an angel tank about 20 years ago. my mom had went and bought a few blue paradise gouramis "to add color to the tank". they got along fine for about a year, then one day my dad came home to find all 10 angels dead, apparently from the gouramis....
