How much lighting/adding sand bed?

[Dorkel Marine 1]

Thank-you Ron 101. It was reassuring to hear someone say the 55watt pc would be alright. Good news today. Had the fridge fixed. Got talking with the guy and he has a big marine set-up and said phone him anytime and he would lay some soft coral frags on me for nothing. Mind you the bill was high enough. going ahead with the sandbed. thanks again.
