i bought a couple of sps from rick last week,more fragile than i imagined,dropped the stuff on a cement floor and they broke into pieces,look like they lost some colour on the trip as well,within a week they both have retained their colour and the smaller pieces have coloured up as well,my zoas have started spreading and never seen them open like this,Xenia and green star polyps all stretching longer than under my older setup,but they were 3 ft from the water where as these LED are 1 ft from the water,I'm extremely happy with the results so far,being a brand new setup i haven't added anything yet as far as minerals except for kalk that i started but haven't refilled yet,was vodka dosing till my pellets matured and the pellets all slimed up so i stopped the vodka and will wait out the pellets to mature,my rock looks very impressive in person as do the pics IMO
