So for the sand, I don't suck it up like the rocks, I just hold it above it?
I haven't had a chance to get frozen food, I plan on doing it tomorrow since I worked too late tonight. I'm thinking about getting a little dish for it to sink into.
I had bought the Whisper EX 30, set it up, to find out it hit the glass of the tank and vibrated it too much for me even. I hate hearing the filter since the tank is in my room. Do you recommend any filters?

Thank you so much for all of your help! This is greatly appreciated!
