I recently visited a lfs in my area and asked the lady where they get their lr from. I noticed the lr was purple - very purple. It looked like purple coraline growing on the lr but it's not. She explained to me that they use a product called 'purple up' to give the lr the purple coraline effect. It looks nice but is it natural and is it safe?
Should the coraline not rather grow on it's own?
Has anyone on the forum used ot before and what effect does it have on the aquarium life and water params?
