Skimmer advice needed

[BlkWolfe]

Never used a skimmer before, but would like to give one or two a shot and see how my tanks react...

First tank is a 72g Aggressive tank, other is a 52g LPS/softie reef. Space is a concern for both, so most likely limited to a HOB skimmer. Not a heavy bioload in either tank, but would like to cut down on maintenance and maybe try some sps in the 52g.

Was looking at getting remora pros for each, but would appreciate anybodies input into them or any other skimmers that you've used on tanks about this size.
