I can definately understand the budget crisis. I am in the same boat. I was only saying something, because I think you could get an aquarium pump for less online than what you spent, and it seemed like the whole question here was more about the UV. Enough said about that! You already have it installed at this point so it's not really worth talking about the $20 buck you might have been able to save. I'm sure that it will work for you for the time you need it to and probably even longer. As for the tight budget, hang in there and keep doing what you're doing. I know better than anyone that these times are not fun, but don't let that stop you from enjoynig your tank build. I look forward to seeing your rockwork.
