what would be the best way to boost coraline algae? im dossing with stromium and iodide and purple up. i have a little bit starting but i would like to completely cover my tank bottm in the purple stuff. any suggestions? i would really like to try to set up a ten gallon that i could grow the stuff in and just transfer rocks from my big tank back and forth. what kind of lighting should i put on the ten gallon for that purpose?
