The thing with 3 emperors is that every month your going to be chaning 6 filter carteridges. and if one of the pumps goes out then 1/3 of all of your filtration is off. If i were in your situation I would take the 3x$50 price of the emperor and put $150 toward a single canister or wet/dry system so there is less maintinence monthly and less money overall to keep the tank up. plus if you put a canister or wet/dry under, you will have much more room on the back of the tank and it won't be so cluttered to put ur aqua c remora on there. I think that would be a great skimmer and a definate positive to have. But if you have the funds, i would ultimately splurge and do a wet/dry, and if you don't, i would still do a cansiter to lower the maintinence and overall monthly payment for 6 emperor cartridges. I know thats not what you want to hear because it sounds like you have your heart set on the emperors but in this hobby, cutting corners for price or skimping on quality doesnt tend to pay off very well in the long run. Just my $0.02
