Hey folks!! First post so if I don't seem clear or leave out some info I apologize. Went to Petco a couple weeks ago and got a 5gal kit. Also bought purified drinking water. I Conditioned the water and threw a couple goldfish and a couple guppies. PH has always been off the scale. Ammonia .25, Nitrite 0, Nitrite 0 after a 1/4 tank change. I am able to lower it with Vinager but that only lasts a couple hours or less. Do the PH adjusters at a LPS work more effectively in keeping the PH down? Will the PH come down naturally as the Nitrogen cycle starts?
