Hey guys. I just ordered a Stevie T media rack for my RSM 250. I was gonna grow chaeto on one of the floors but trying to figure out how to provide light...does anybody know if paint can be scraped off the back in order to allow a magnetic light to shine thru? Also any media suggestions for the rack would be well received...Im thinking chaeto on bottom, then purigen, then chemipure elite, then phosban, then filter floss...what say you?
