I started a 10 gallon tank 6 weeks ago. At the moment I have 4 Tetra Barbs and four Cory cats bottom feeders. In the last couple of weeks I have lost 3 fancy guppies, a male and female swordtail. Yesterday I bought 4 mollies, two were black and two were spotted Dalmatian. This morning found the four mollies dead. I checked the ph and could not get a reading on my chart. Must be below 7 or lower. How could my ph drop down so low.
