Hi Everyone, just Starting Out:)

[mumster]

Hello, I am new to reefing and I`m so excited. I have been reading and following along on the forums for several months now. Thank you for all the covert advice. I have some simple questions:
1. do i need a tank cover, I`d rather not if possible.
2. when do i do any cleaning of the sand , tank is one week old.
3. do i clean the filter material in the same manner as for a freshwater tank, by rinsing it in the water taken out when cleaning and doing a water change. ( sorry there are no question marks, my keyboard is being stupid and i havn`t figured out how to change it back).

I will do a more complete indepth post about my tank and what I have, but I have to run out for a while. Thanks for all your help. Krista
