There is no way that skimmer is going to be big enough.
There are tons of options out there, but I know several people who are using aquac's EV series on their shark tanks, I have used these skimmers and they are great for the price.
Once again that is one persons opinion, I am sure you will get others but that skimmer will not be big enough.
You also might want to consider putting this pond in your basement or something, because unless you have a very large room you are probably not going to be able to fit this into your room. There is also the issue then with moisture levels in your room. All sorts of things to take into consideration.
