i have one - although mine is only the standard (w/o UV)
I like it on my 50 gallon -- i think that is a good fit - they say up to what 70 or 80 gal?? the skimmer part is probably good for that size (70-80)but the power filter part might be undersized -- also filter cartirages are hard to find so far. seems that via-aqua did not have enough made when they introed the skimmer. i was able to order them direct though.
I am considering the UV that use on occasion but the norm is 15 watts and theirs is only 5 (you can buy it separatly if you dont buy the deluxe)
how much do they what for it?? I paid too much for mine at LFS. do a search on google (i think it onlys pulls up about three finds if you search "viaaqua multi-skimmer) and the deluxe is like 120 and the standard is about 80
