Let's see....where to start. I have a 30 gallon cube that has been running for 5-6 months. It had a piece of what I know is limestone in it that I removed from the tank 10-14 days ago. There is another rock that I *thought* wasn't limestone still in there (a smooth, round, white, grey and black swirly patterned rock). Today I finally got around to picking up a ph test kit. The water in that tank is off the charts (7.6 or above). My tap water is 6.4-6.6. The limestone that I removed from the 30 gallon is now in a new 10 gallon tank, and that water is testing off the charts too. All fish are doing great....the 30 is a community tank, and the 10 is a quarantine for now with a couple of ghost shrimp and guppies. I'm hoping to convert it to a RCS tank.
Am I worrying for no reason? Should I remove the rocks?
This fish business is tough!!!
