well, all I can say is I have a remora pro that has been running on a rubbermaid tub (about 60 gallons or so) of water with my 30 lbs of crappy lalo live rock in it... I added the remora pro (with mag 3) on Friday around midnight, instructions said to wash it so it would start skimming faster, so I ran hot water through it, slapped it on the tub, and by saturday morning had a thick wet skimate, about 1cm worth on the bottom of the collection cup. I was expecting it to take longer than 5 hours (got home from work at midnight, left for work at 5 AM).
It has slowed down now, I think it 'caught up' (in other words cleaned out the muck and is not holding steady) but I was really suprised at how fast it started working, I had understood that new skimmers took a couple of days to break in. If this is what it can do breaking in, I am even happier.
The remora pro is rated, I believe, for tanks over 70 gallons, so if you want a hang on back skimmer, or a ready made in-sump skimmer (urchin) then I don't think they are bad choices. Certainly having one of our wizards of maast make you a customized one, or going with some of the other first rate skimmers would not be a bad idea either.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
