Sorry not to make it more clearer, I dont want to talk about my tank size yet but its more than 100+ gallons. So I have a coralife 125 power skimmer running but I see its NOT ENOUGH FOR THE BIO LOAD I WILL HAVE. the only thing I like about it is that u can make it quite by connecting the air tube to a divce that mutes its noise. The nano skimmer is cool but I would only use it for a tank of 10 gallons or less.
