The tank that I am having a problem with is my 30gal tank. I recently moved and therefore went from city tap, to well water. I had to drain my tank in order to move it. Well now that it has been set up in my home for about a week using well water I am having problems with my levels in the PH and alkaline areas. My nitrate levels are fine, my hardness of the water is soft, but my alkaline level is the lowest level that can be registered and my PH is sitting at a acidic level. I purchased some API brand "Proper PH 7.0" from PetSmart in hopes that it would raise my PH to a neutral level for my tropical fish. 2 days ago 5 of my fish died. So I did a 50% water change and added some more aquarium salt and the amount suggested of the "Proper PH 7.0". WELL IT DIDNT WORK !!!!!! PH is still sitting at acidic and alkalinity is on the lowest side. IDK what to do .... Please HELP !!!!!
