UPDATE!! Well this aint much about the construction but I am gonna try and get the LR racks built today. I need to do this soon since they take 5 days to cure. This is a project that I am very very excited about. I have been researching this for the past week and have found some very very neat ideas and have incorporated a few of them into this design. These will both work as racks for the rocks and also a home for cryptic sponges and pods!!!! I will photo the whole process.
