Ok, I've read and read and read, was going to do saltwater then changed to freshwater. I've put more effort into this than I did either of my dog purchases, so I'm pretty sure my heart is in the right place, but I'm still confused about what I should do. I have a 55 gallon tank that was up and running for a week without fish and I currently have a dwarf gourami, 2 mollies, 2 guppies, an angel, and a clown loach over the last two weeks. I test my water every other day and it seems the parameters are fine. But after lossing two fish (another dwarf gourami and angel) I took my water to Petsmart to be tested they say my ph is too high. I'm not sure what to do, my test says its in the low range. My water is a little cloudy, and I know I need to do a water change today, but do I need to worry about the ph?
