Well this is the second glass top i have cracked and is getting covered in salt every few days. I dont really feal like buying another one and im getting sick of cleaning it every 3 days, Would it be bad to go topless or would i evaporate to much water. right now im evaporating about a half a gallon a day on my 29g(no sump/refuge). Would the lighting which is mounting on legs get salt spray or would i be alright? putting a order in for the 2x40w system for the 10g figured i would everything i need now. Thanks
