I am planning to buy LR locally from established tank. What should I look for in LR beside coraline algae. I don't know how to determine good quality. How to differentiate good quality LR from others?
Coraline algae does not denote good LR
I would look for peices that are light for there size
Thanks, but there are lots of people selling LR from established tank (btw i was suggested to buy it from established tank rather than from fish store), how would I know who is selling good quality LR (I don't know may be the one with lots of life form visible on it are good quality rocks)? I appreciated that you are trying to save me money by going for lighter rock with good size, but I also want to get good quality rocks. Please help me if you know how to identify good quality LR.
