Just some opnions of my own.
Many reefers claim different brands of skimmers to be the best and swore by it.
Reefers with deep pockets can spend $2000-$3000 on skimmers alone.
To me, rather than to pay $2000-$3000 for a skimmer or use a 4 footer beckett, i rather do the following:
IF i ever get a new set up: i will put a 6 inch by 24 inch beckett skimmer, along with a deltec needlewheel and a schuran jetskim 120 skimmer.
Best of both worlds, beckett combine with needlewheel. No more complains.
