Im talking about the giesman and they are IMO a total waste of money
but if one have to much money and want to trow it they are the #1 choice 
you could have a complete wood canopy and beter lightning system and you will have some money left to buy a becket skimer 
the canopy will completly close every ting under and over the tank and you would not see salt creep or any hose + it cut the light between the lamp and the tank and give beter view in the tank 
here is a pic of wath I meen compare this to a tank with ugly chain and a 
blue fixture with a metal rack under I dont see any advantage
