The eshopps psk 150 is rated for 150g. The rule of thumb with skimmer is usually to get one that is rated for 1.5-2.0 X your water volume. BUT having said that, I find the 150 works really well on my 125g reef. I need to empty the cup every other day or so and it pulls a VERY nasty skim. lol
Like I said too i was limited in space in my sump so the eshopps with its small footprint was the only thing i could fit in the section of the sump. lol
Bottom line on the eshopps skimmer is that I had one and liked it so much i just bought a second one for my 60g tank. lol I have a reef octopus on one tank and unlike any one else, I am not a big fan.
Hope that helps!

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
