At last my stand has arrived after several hiccups and a very long wait. I've now started setting the tank up. I do have a few queries which I would like some advice on, firstly I have washed the sand but the piece of bogwood that I have had soaking for three weeks is still staining the water. I was hoping to attatch some plants to it along with some in the substrate, let it settle for a few days and then start the fishless cycle, but now I'm not sure if the bogwood is safe to put into the tank whilst it is still staining the water? Secondly am I right in thinking the ammonia added in the fishless cyle is not harmful to plants during the process? Finally, do I leave the carbon cartridge in place throughout the cycle or will it hinder the process? Thanks for your advice in advance!
