my ph is 6.0 but all my other tests are perfect, my fish are doing fine except my mr gurami that passed away yesterday, 1st fish ive lost in the last 2 months. my fish have had babies but cant understand why my ph is so low. 


the ph in the tap is 7.0, i let the water stand in buckets overnight with water conditioner every week b4 my 25% water change. I have a 180 ltr tank with bogwood, 2 live plants & 2 artificial plants.Is it 6.0 out of the tap?
