Aquarius, good news! My husband brought the new hood and air pump home last night, and it is of pretty decent quality. The hood is a Hagen brand, not sure of the air pump. The air pump is much quieter than the other, and the hood with lights fits much better and has the proper cover to protect the lights from moisture.
I've posted in my other thread about filters that we are going to go with fishless cycling as it sounds much more healthy for the fish, so wish us luck in our new adventure.
Edited to add that the manager at our Petcetera store was nothing but helpful with the tank problem. It's good to see that some people are still customer-focused in this day and age, especially in a chain store. I fully expected to be told that we should suck it up because we bought a sale kit.
