Hey Everyone I am not happy with the rock I currently have. Mainly because there are too many areas for stuff to get caught in. Every time I clean the tank, the amount of crap that I get from the nooks and cranny's is incredible. I know that every rock is going to have these, but the way this rock is, it just holds so much. So, I'm going to get some new stuff. Just wondering how long do you think it will take to cure? Its only a 50L tank, and I was thinking of adding just a small piece at a time over an extended period. Thoughts?
