Which H.O.B. do you think is better? Evidence? I tried to search, but it has been broken for several hours....

I have read a lot of good about the octopus and that it produces a ton of skimmate, i havent heard too much about the remora...

any advice or opinions on which i should get? its for a 30 gallon reef tank, perhaps will find a new home on a 55gallon in spring.
