from what Im hearing the space monsters grow like a weed( I certainly hope so).......my single head CAR frag melted as well.....I have a three header now that seems to be doing ok.......
man with that frag tank lighting you should get a wee bit of growth.....but ya, you may need a small army of critters and fish to keep things in check....
so, how are you liking the 6 radions?.....do you think that is enough for your footprint now?.....Im not a student like you so I cant afford a whack of them at once
but I did pick up one for the upgrade today.....
