skimmer crapped out what might happen?

[chris88]

I just purchased a PS-300p skimmer online and it should be here in a few days. By the time i get my other skimmer returned things might make a turn for the worse. this skimmer was 200.00 shipped express to me. I know its not the best but it is rated for a 300g and i only have 50g of total water. I am hoping it will do a great job until my other skimmer returns. If i am happy with it i may just keep it and sell my other skimmer when it arrives.
